Which Advisors Structure Complex CRE Debt? | Thorne CRE

Independent commercial mortgage capital advisors, specialized real estate investment banking intermediaries, and healthcare debt advisory firms help structure complex commercial real estate debt. These advisors evaluate senior debt, mezzanine tranches, CRE debt funds, and SBA programs to optimize proceeds, debt service coverage, and equity requirements for practice acquisitions, owner-occupied facilities, and transitional commercial real estate assets.

Which Advisors Help Structure Complex Commercial Real Estate Debt?

When commercial real estate transactions involve owner-occupancy, medical build-outs, specialized operating covenants, or non-stabilized occupancy, standard off-the-shelf bank products frequently fall short. Three main categories of advisory professionals specialize in arranging and structuring complex CRE debt:

• Specialized Commercial Capital Advisors: Boutiques like Thorne CRE act as borrower advocates across non-recourse debt, senior bank facilities, Certified Development Companies (CDCs), and private balance-sheet lenders. Review our guide on the essential checklist before choosing a commercial mortgage broker.
• Commercial Real Estate Investment Bankers & Intermediaries: These institutional advisors structure multi-tiered capital stacks—pairing senior syndicated mortgages with preferred equity or mezzanine debt for institutional-scale deals.
• Debt Advisory & Loan Restructuring Specialists: When deals involve maturing facility obligations, tight covenants, or low DSCRs, restructuring consultancies structure interest reserves, note modifications, or A/B note splits. Learn more about how to navigate these challenges using our commercial mortgage maturity risk checklist.

Advisor Selection Criteria & Thresholds

To determine which advisor fits your transaction, evaluate these baseline qualification standards:

• Lender Network Breadth: Ensure the advisor actively places capital with regional balance-sheet banks, life insurance companies, and leading private credit funds, rather than routing deals to a single preferred correspondent.
• Underwriting Expertise: Advisors must model dual-entity cash flows (Operating Company/Eligible Passive Company), calculate global debt service coverage ratios (DSCR), and stress-test variable rate resets against current Federal Reserve benchmark rates.
• Fee Structure Transparency: Professional structuring mandates typically carry a 0.75% to 1.50% advisory fee paid strictly at loan closing, with no non-refundable upfront placement retainers unless bespoke financial modeling is contractually required.

CRE Debt Funds & Commercial Real Estate Debt Fund Solutions

When conventional institutions or SBA programs cannot accommodate short execution windows, transitional occupancy, or major clinical repositioning, a commercial real estate debt fund provides non-bank bridge liquidity. A CRE debt fund is a private investment vehicle managed by non-bank institutional sponsors that originates, underwrites, and services private balance-sheet loans secured by commercial property.

Unlike depository banks subject to rigid OCC and FDIC regulatory capital reserve requirements, a commercial real estate debt fund can underwrite future value, lease-up projections, and heavy medical or surgical conversions. For properties encountering leasing headwinds or DSCR compression, pairing private bridge facilities with an interest reserve structure vs cash in refinance for low DSCR provides vital operational runway.

CRE Debt Funds vs. Banks vs. SBA: Capital Stack Comparison

In 2024 and 2025 benchmark markets, spreads for private credit funds have tightened, providing viable short-term bridges to permanent capital:

Feature	CRE Debt Fund (Private Credit)	Conventional Bank Loan	SBA 504 / 7(a) Facilities
Target Loan Size	$3,000,000 to $100,000,000+	$1,000,000 to $25,000,000	$500,000 to $15,000,000 (total project)
Pricing / Index (2024–2025)	SOFR + 350 to 650 bps (8.50%–11.50%)	SOFR / Treasury + 200–300 bps (6.50%–7.75%)	SBA Debenture: 10-yr UST + spread (~5.85%–6.75% fixed)
Leverage Limits	Up to 75%–80% LTC (As-Is / As-Stabilized)	65%–75% LTV	Up to 90% LTC (Owner-occupied)
Recourse Profile	Non-recourse standard (bad-boy carveouts)	Full recourse typical (>20% owners)	Full personal guarantee mandatory (≥20% owners)
Underwriting Focus	Pro-forma cash flow, renovation scope, exit value	Historical 2–3 yr trailing DSCR (>1.25x)	Global clinical cash flow + owner-occupancy
Closing Horizon	21 to 35 business days	45 to 75 days	60 to 90 days

Core Capital Structures for Doctor Office Acquisitions

Leasing clinical space feels manageable early on. Over a decade, though, writing massive rent checks to a commercial landlord simply drains capital that could build partner net worth. Medical office buildings (MOBs) bring a unique credit profile to commercial lenders. Yes, clinical facilities demand expensive mechanical build-outs, specialized interior build-outs, and rigid zoning compliance. But licensed physicians also show some of the lowest commercial default rates in the entire lending market. Banks know this. Because patient demand stays durable across economic cycles, lenders offer aggressive programs that let medical groups buy, expand, or construct facilities without draining operating reserves.

In our advisory work at Thorne CRE, we walk physician groups through three primary financing routes: the Small Business Administration (SBA) 504 loan, the SBA 7(a) loan program, and balance-sheet commercial portfolio mortgages from regional banks or institutional credit unions. Review our breakdown of SBA 504 vs 7(a) for owner-occupied property. Finding the right vehicle comes down to a few variables: total project cost, required tenant improvements (TI), how practice partners share equity, and whether third-party clinical tenants will occupy spare suites in the building.

For an established practice buying an existing building or funding a ground-up development, the SBA 504 program is often the premier option. It uses a tiered capital stack structured as a classic 50/40/10 breakdown:

• Senior First Mortgage (50% of Project Cost): Underwritten and funded by an approved commercial bank or non-bank balance-sheet lender. This note holds the first-lien position on the real estate, generally structured on a 10-year term with a 25-year amortization schedule or as a fully amortizing 25-year fixed loan. Compare rate expectations in our commercial property loan interest rates guide.
• Junior Second Mortgage (Up to 40% of Project Cost): Funded through an SBA debenture issued by a regional Certified Development Company (CDC) and backed by a full federal guarantee. This tranche delivers a long-term, below-market fixed interest rate for 20 or 25 years, secured by a subordinate second lien on the property under statutory guidelines governed by the SBA Standard Operating Procedures (SOP 50 10).
• Borrower Equity Injection (10% of Project Cost): Contributed by the practice or a dedicated property holding entity. For multi-specialty medical groups, primary care practices, and dental offices with at least two years of operating history, the minimum down payment is held at just 10%. That leaves 90% of your capital intact for payroll, clinical equipment, recruitment, and operating reserves.

When a transaction needs higher loan-to-cost ratios or folds in an ongoing clinical business purchase, the SBA 7(a) program steps in. The SBA 7(a) carries a statutory gross lending ceiling of $5,000,000. However, medical practices can often achieve 100% loan-to-cost financing by pairing a primary SBA 7(a) loan with an eligible seller carryback note. Under standard SBA rules, a seller note satisfies the required equity contribution as long as it is placed on full standby for an agreed term. When buying out a retiring physician who owns both the operational chart base and the physical real estate, this tool lets incoming partners take ownership with minimal out-of-pocket cash.

Conventional portfolio loans work differently. Regional banks, credit unions, and life companies originate these directly onto their own balance sheets without any government backing. They bypass federal program packaging fees and programmatic leasing restrictions, which is great. The catch? Conventional facilities almost always demand 20% to 30% down, and they love short balloons at year 5, 7, or 10. For medical practices that want to keep cash on hand, the 10% down payment threshold of an SBA 504 usually beats conventional loans handily. You can also explore customized solutions across varying deal sizes and property types.

Do not forget the cost of specialized clinical build-outs. Buying medical real estate is rarely just purchasing brick and drywall. Clinical space requires heavy mechanical, electrical, and plumbing (MEP) work, dedicated HVAC air exchanges for minor procedure rooms, lead shielding for radiology suites, surgical scrub sinks, and medical gas lines. Both SBA 504 and 7(a) programs let you roll architectural fees, engineering reports, environmental testing, and interior renovations straight into the total loan balance. You finance those long-term build-out costs across a 25-year amortization window instead of burning cash or taking out expensive short-term equipment debt.

Underwriting Criteria: How Lenders Evaluate Healthcare Real Estate

Underwriting a medical office is nothing like underwriting an industrial warehouse. Credit analysts do not view a clinic simply as passive bricks and mortar. Instead, lenders evaluate the practice itself, underwriting the operating business cash flows to confirm that physician billings can handle ongoing clinical overhead alongside property debt service.

The core metric is the Debt Service Coverage Ratio (DSCR). For healthcare properties, bank underwriters and CDC credit committees want a combined global DSCR of at least 1.20x to 1.25x. That coverage is assessed across two balance sheets:

1. The Real Estate Holding Entity: The property must earn enough contractual rent from the medical practice to service the first and second mortgages, real estate taxes, property insurance, and long-term replacement reserves.
2. The Medical Operating Entity: The operating practice must generate sufficient cash flow (measured as EBITDA, adjusted for physician distributions and personal debt) to support ongoing clinic operations, staff compensation, and lease payments with breathing room.

Credit analysts dissect your payer mix and provider roster. A practice with a healthy split across commercial PPOs, Medicare, and private plans is viewed as low-risk. Conversely, practices relying heavily on Medicaid or high self-pay patient bases face closer scrutiny due to tighter margins and slower reimbursement cycles. Credit analysts also pull historical accounts receivable (A/R) aging reports, with special focus on balances older than 90 and 120 days. When net collection rates sit steadily between 92% and 96%, underwriters know those billing figures reliably convert to collected deposits. In refinancing scenarios, owners can compare terms using our analysis on commercial real estate refinancing rates and debt strategies.

Then comes the 51% owner-occupancy rule under SBA guidelines. To access 90% financing through the SBA 504 or 7(a) programs, your medical group must occupy at least 51% of the total rentable interior space. You can lease out the remaining 49% to outside tenants. An imaging clinic, physical therapy group, or compounding pharmacy makes an ideal neighbor. Better yet, that tenant rental income helps support your global debt service calculations, provided you have executed leases or verified market rent figures in hand.

To keep clinical malpractice liabilities separate from real estate assets, medical practices standardly rely on an Eligible Passive Company (EPC) and Operating Company (OC) structure. In this framework, the doctors create a separate holding entity (the EPC), usually an LLC, to purchase the real estate. The clinical practice (the OC), typically set up as a PLLC or professional corporation, executes a formal lease with the real estate LLC. That lease should be drafted as a triple-net (NNN) contract with an initial term matching or exceeding the 25-year debt term. This legal separation ensures patient lawsuits stay contained within the practice entity, while giving the partners clean depreciation write-offs and tax deductions on the real estate side.

Borrower Diligence Checklist: Underwriting Submission Package

Putting together an organized diligence package up front cuts weeks off your review cycle and avoids endless back-and-forth with credit committees. Here is what we include in a complete loan application file:

• Historical Operating Practice Financials: Three consecutive years of filed federal business tax returns (Form 1120-S or 1065) for the operating practice, plus year-to-date interim P&Ls and balance sheets with prior-year comparative columns.
• Clinical Production and Operational Reports: Practice management summaries from the past 24 months outlining gross charges, net collections, active patient counts, provider billing summaries, and detailed accounts receivable broken into 30-, 60-, 90-, and 120-day buckets.
• Payer Mix Summary: A clear percentage breakdown of collections across commercial insurers, Medicare, Medicaid, workers’ compensation, and direct patient out-of-pocket payments.
• Personal Financial Schedules: Three years of signed individual tax returns (Form 1040) plus SBA Form 413 (Personal Financial Statement) for any partner holding an ownership interest of 20% or greater in either the practice or property entity.
• Real Estate Purchase Documentation: A fully executed Purchase and Sale Agreement (PSA) containing clear assignment provisions to your real estate EPC, outlining inspection periods, environmental contingencies, and closing dates.
• Phase I Environmental Site Assessment (ESA): A clean Phase I ESA completed by a qualified environmental firm. If the building contains medical imaging rooms, dental facilities with historical mercury traps, or backup diesel generators, include all relevant disposal logs and radiation filings.
• Formal EPC/OC Real Estate Lease: A draft triple-net (NNN) lease between the property company and the clinical practice, establishing rent sufficient to pay all debt service, taxes, insurance, and maintenance reserves.
• Tenant Improvement (TI) & Equipment Scope: Itemized contractor bids and floor plans for necessary clinical updates, mechanical modifications, and affixed medical hardware being funded through the loan. Working with an advisor for expert commercial loan consultancy accelerates these clearances.

Worked Financial Example: Structuring a $3,500,000 Medical Building Acquisition

Let us walk through how this works in practice. Suppose a four-partner orthopedic group currently rents space in an expensive medical corridor. Rent escalations are cutting into partner draws, and their landlord is unwilling to fund needed facility improvements. The physicians locate an independent, single-story 10,000-square-foot medical office building nearby. The deal involves acquiring the real estate and funding clinical updates for an in-house physical therapy room, digital X-ray suite, and clean procedure rooms.

Here is the total project capitalization:

• Real Estate Purchase Price: $3,250,000
• Clinical Renovations and Build-Out Upgrades: $250,000
• Total Capitalized Project Cost: $3,500,000

Instead of coming up with $700,000 to $1,050,000 for a conventional 20% to 30% bank down payment, the group uses an SBA 504 structure at 90% loan-to-cost:

• Senior First Mortgage (Bank, 50%): $1,750,000 provided by a commercial lending institution at 6.75% interest on a 25-year amortization schedule with a 10-year initial term.
• Junior Second Mortgage (SBA/CDC Debenture, 40%): $1,400,000 funded through an SBA 504 debenture. This piece carries a fixed rate of 5.85% (including annual CDC and servicing fees) fully amortized over 25 years with zero balloon risk.
• Borrower Equity Contribution (10%): $350,000 total equity split equally across the four physician partners ($87,500 each), funded from practice cash reserves.

Using this program keeps between $350,000 and $700,000 in liquid capital inside the business. The practice retains that capital to cover working capital needs and patient billing cycles rather than tying it up in real estate equity.

Here is how the monthly debt service (principal and interest) shakes out:

• Bank First Mortgage ($1,750,000 at 6.75%, 25-yr am): $12,088/month
• SBA Debenture ($1,400,000 at 5.85%, 25-yr am): $8,884/month
• Combined Monthly Debt Service (P&I): $20,972 (roughly $251,664 annually)

Before purchasing, the practice leased 8,500 square feet at $32.00 per square foot NNN, plus $5.40 per square foot in operating expenses (CAM, taxes, and insurance). Their previous lease costs were:

• Annual Base Rent: 8,500 RSF × $32.00/RSF = $272,000
• Annual CAM / NNN Expenses: 8,500 RSF × $5.40/RSF = $45,900
• Total Annual Rent Outflow: $317,900
• Total Monthly Lease Payment: $26,492

In the new building, the practice occupies 7,500 square feet (75% owner-occupancy, easily meeting the SBA threshold). The remaining 2,500 square feet is leased to a local podiatry clinic at a market rent of $30.00 per square foot NNN. That outside tenant brings in $75,000 per year ($6,250 every month), significantly lowering the orthopedic group’s overhead.

The net numbers look like this:

• Monthly Loan Payments (P&I): $20,972
• Taxes, Insurance, and Capital Reserves: $4,500
• Gross Monthly Real Estate Expenses: $25,472
• Less Podiatrist Subtenant Rent: -$6,250
• Net Monthly Occupancy Cost for the Practice: $19,222

By buying the property, the group trims its monthly occupancy check from $26,492 to $19,222. That is an immediate operational savings of $7,270 per month ($87,240 annually). Over the first five years, the partners pay down over $380,000 in loan principal while capturing property appreciation, building equity, and leveraging tax advantages like cost segregation and accelerated building depreciation.

Acquisition Execution Timeline: From Letter of Intent to Funding

Closing on a medical facility takes active project coordination across your legal, financial, and construction teams. A clinical practice cannot afford unexpected downtime, so hitting timeline milestones is critical, especially when coordinating lease expiration dates. A typical closing cycle runs roughly 60 to 75 days.

1. Days 1 through 15: Letter of Intent (LOI) & Preliminary Underwriting
   The practice selects the property and executes an LOI specifying a 60- to 75-day escrow. At the same time, we assemble your financial file (tax returns, production reports, and personal balance sheets) to run competitive terms across lending partners and CDCs. The doctors review term sheets, select the best facility, and wire initial underwriting deposits.
2. Days 16 through 45: Credit Approval, Medical Appraisal & Environmental Diligence
   The senior lender underwrites the file and issues a formal credit commitment. During this stage, two key third-party reports get ordered:
   • Healthcare Real Estate Appraisal: The appraiser analyzes the property using sales comparisons and income capitalization, factoring in clinical utility, surgical plumbing, and parking ratios (medical offices need 5.0 to 6.0 stalls per 1,000 square feet, compared to 3.0 to 4.0 for basic office).
   • Phase I Environmental Site Assessment (ESA): An environmental specialist examines soil, groundwater, and historical building uses to meet standard SBA and institutional risk standards.

   With underwriting complete, the lender packages the submission to the SBA for final debenture review.

3. Days 46 through 65: SBA Authorization, Title Resolution & Lease Finalization
   The SBA processes the file and issues its formal SBA Authorization. This document details pre-closing conditions, insurance requirements, and borrower equity verifications. Meanwhile, your real estate attorney completes the EPC/OC lease, title exceptions get addressed, and final contractor bids are locked down.
4. Days 65 through 75: Closing Documentation, Escrow Funding & Asset Transfer
   The partners sign closing binders, including bank notes, CDC debenture commitments, organizational certificates, and personal guarantees. The 10% cash down payment is wired to escrow, lender proceeds are funded, the county records the deed, and property ownership transfers to the physicians’ holding entity.

Frequently Asked Questions

Can a doctor buy their own medical office building with 10% down?

Yes. By utilizing an SBA 504 loan structure through an Eligible Passive Company (EPC), physicians can acquire medical office real estate with a 10% down payment, provided the medical practice occupies at least 51% of the building’s rentable square footage.

Which advisors help structure complex commercial real estate debt?

Specialized commercial capital advisory firms, real estate investment banking teams, and private debt intermediaries help structure complex CRE debt. They coordinate senior lenders, subordinate tranches, CRE debt funds, and government-guaranteed programs to negotiate favorable leverage, DSCR covenants, and amortization terms.

When should a borrower use a commercial real estate debt fund instead of a bank?

A borrower should utilize a commercial real estate debt fund when an asset requires non-recourse financing, rapid execution (closing within 21 to 30 days), transitional bridge funding for vacant or value-add space, or when historical DSCR ratios do not yet support traditional bank underwriting thresholds.

What is the minimum DSCR required for medical office debt?

Commercial lenders and SBA CDCs typically require a minimum global Debt Service Coverage Ratio (DSCR) between 1.20x and 1.25x across both the real estate holding entity and the operational clinical practice.
