How to Refinance a Multifamily Property

To refinance a multifamily property, define the purpose of the new loan, confirm whether the property has two-to-four units or five or more units, calculate the loan amount supported by both value and cash flow, compare complete written terms, and submit a reconciled operating file. Proceed only when the new loan improves the property’s financing over your expected hold period after closing costs, prepayment charges, reserves, and maturity risk.

Decide Whether to Refinance Before Requesting Quotes

Start with a measurable objective: replace maturing debt, reduce the payment, change the rate structure, fund repairs, remove a lender restriction, or take cash out. Record the current loan balance, payment, rate, maturity, prepayment terms, and required payoff date. Then define the minimum result the new loan must produce.

Keep the existing loan if realistic refinance terms do not improve the outcome. Common reasons to wait include a low fixed rate, a large prepayment charge, incomplete renovations, unstable occupancy, unresolved title or insurance issues, or a hold period too short to recover the transaction costs.

For a payment-saving refinance, calculate:

Break-even months = total refinance costs ÷ monthly payment savings

Use a full cash-flow comparison when the refinance changes loan proceeds, amortization, maturity, principal reduction, or risk. A simple break-even calculation does not capture those differences.

How to Refinance a Multifamily Property in Eight Steps

1. Confirm the property classification

Count the legal residential units and identify owner occupancy, commercial space, short-term rentals, affordable-housing restrictions, and nonconforming use. Classification comes first because it determines which loan programs, income calculations, appraisal forms, and documents are relevant.

Two-to-four-unit properties may qualify for residential investment-property or business-purpose financing. The Fannie Mae Selling Guide’s rental-income rules describe documentation and calculation methods for eligible one-to-four-unit residential transactions. Properties with five or more units are generally underwritten as commercial multifamily real estate, using property cash flow, collateral, and borrower or sponsor capacity. The OCC’s commercial real estate lending guidance describes those core underwriting considerations.

2. Calculate current property performance

Prepare a trailing-12-month operating statement from leases, deposits, invoices, tax bills, insurance records, payroll, and utility statements. Reconcile collected rent to the rent roll. Separate recurring operations from capital improvements, debt payments, depreciation, income taxes, insurance claims, and other nonrecurring items.

For a commercial multifamily property, begin with:

Net operating income = effective gross income − recurring operating expenses

Then calculate the proposed coverage:

DSCR = underwritten net operating income ÷ annual debt service

If underwritten NOI is $240,000 and annual debt service is $192,000, DSCR is 1.25. The lender may use different rent, vacancy, expense, reserve, or debt-service assumptions. When a program qualifies from gross rent instead of property-level NOI, the gross-rental-income calculation must follow that program’s lease, market-rent, vacancy, and documentation rules.

3. Estimate the maximum loan amount

Test value and cash flow separately. The value limit is:

Maximum loan from value = permitted LTV × underwritten property value

The cash-flow limit is the loan amount whose payment satisfies the lender’s DSCR, debt-yield, or other coverage requirement. Use the lower applicable result as the working maximum. Then subtract the current payoff, lender fees, third-party costs, required repairs, and reserve deposits to estimate net proceeds.

Run a downside case with a lower value, higher interest rate, higher expenses, and less qualifying income. Do not depend on cash-out proceeds that disappear under a modest change in assumptions.

4. Select the loan structure

Match the structure to the property and business plan. Rental-income loan programs use property income differently, so obtain the lender’s exact calculation before comparing proceeds. When several properties are involved, compare separate loans with portfolio and blanket loan structures, including the conditions for releasing or substituting collateral.

Government-insured financing is a distinct option, not a default choice. HUD’s Section 223(f) program applies to eligible existing multifamily rental housing with at least five residential units and has program-specific property, repair, documentation, and mortgage-insurance requirements.

5. Prepare a reconciled refinance file

Submit one consistent set of property, borrower, and loan records:

• Current rent roll with lease dates, contract rent, deposits, delinquency, and vacancy
• Current leases, concession schedule, and collection history
• Trailing-12-month and year-to-date operating statements
• Property financial statements and tax returns when required
• Tax bills, insurance declarations, and owner-paid utility records
• Current mortgage statement, note, and written payoff
• Recent bank statements and evidence of required liquidity or reserves
• Entity documents, ownership chart, resolutions, and identification
• Capital-improvement history, repair schedule, contracts, and invoices
• Prior appraisal, survey, title policy, environmental report, or property-condition report if available
• Borrower or guarantor financial statement, real-estate schedule, and experience summary when required

Resolve differences among the rent roll, deposits, leases, and operating statement before submission. Label one-time income and expenses. Provide a short written explanation and supporting record for each material variance.

6. Compare written quotes on the same assumptions

Ask each lender to quote the same requested loan amount, property value, transaction purpose, term, amortization, and cash-out amount. Compare:

• Rate, index, spread, caps, reset dates, and rate-lock conditions
• Monthly payment, amortization, and interest-only period
• Origination, underwriting, legal, appraisal, environmental, and servicing fees
• Prepayment penalty, yield maintenance, defeasance, and lockout
• Maturity, balloon balance, extension options, and renewal discretion
• Recourse, guarantees, carve-outs, and required borrowing entity
• Operating, tax, insurance, repair, and replacement reserves
• Cash-management triggers, reporting duties, and lender controls
• Required repairs, completion deadlines, and holdbacks
• Minimum net proceeds and every condition that can change them

Calculate cash required at closing, cash received at closing, monthly debt service, balloon balance, and total expected cost through the planned exit date. Choose from those totals rather than the advertised rate.

7. Manage appraisal and underwriting

Confirm which third-party reports are required, who orders them, the deposit amount, and whether any deposit is refundable. Provide accurate leases, rent roll, operating statements, access instructions, and improvement records. Track every underwriting condition by responsible person, due date, and status.

If value or underwritten cash flow is lower than expected, identify the exact input causing the reduction. Correct factual errors and support disputed rent, vacancy, expense, or condition assumptions with leases, invoices, operating records, or relevant market evidence. A DSCR appraisal can affect both collateral value and qualifying rent. If the lender’s supported conclusion remains lower, reduce the loan, contribute cash, change structures, or delay the refinance.

8. Review final terms and close

Compare the final loan documents with the approved term sheet. Confirm the rate, payment, amortization, maturity, payoff, net proceeds, reserves, prepayment terms, guarantees, cash-management provisions, repair obligations, reporting requirements, and permitted use of proceeds. Resolve title, entity, insurance, appraisal, and payoff conditions before scheduling funds.

For cash-out transactions, preserve the closing statement and a traceable record of each disbursement. IRS Publication 527 explains that points paid to refinance a rental-property mortgage are generally deducted over the new loan’s term and that interest allocable to nonrental use generally is not deductible as a rental expense. The treatment of rental-property loan interest depends on the use of proceeds and the borrower’s facts. Obtain transaction-specific tax and legal advice before closing.

Final Refinance Decision

Proceed when the final loan satisfies the original objective, remains supportable under reasonable downside assumptions, and improves the property’s financing through the planned exit date. Stop or renegotiate when final proceeds, payment, reserves, recourse, prepayment restrictions, repairs, or maturity differ materially from the terms used to make the decision.

The disciplined sequence is straightforward: classify the property, reconcile its operating results, size the loan from value and cash flow, select the appropriate structure, compare complete written terms, and verify the final documents before closing.
