How to Get an Apartment Building Loan: Steps and Timing
An apartment building loan is a commercial mortgage used to buy or refinance a rental building of five or more units, and you get one in six stages: assemble the property's financials, compare term sheets, clear third-party reports, pass underwriting, get approval, then close.
Key points
- Reconcile the rent roll, operating statements and bank deposits, and explain every difference.
- If you're buying, the environmental review behind federal cleanup liability protection must be done or updated within one year before closing, and five of its parts within 180 days.
- Before signing a bridge, size the permanent loan that repays it in a downside case and compare the gap with your cash at maturity.
Which kind of apartment building loan are you applying for?
| Loan type | Fits | What changes | What slows it |
|---|---|---|---|
| Bank or life-company permanent | A stable building whose collected income covers the payments | Underwriting rests on the rent roll and statements | Books that don't tie to deposits |
| Agency (GSE-backed) permanent | A stable building | Standardized underwriting and loan documents | GSE review and rate-lock timing |
| Bridge | Lease-up or renovation | Package adds the renovation budget; underwriting tests the loan that repays it | Budget questions, extension tests |
| HUD-insured 223(f) | Purchase or refinancing of existing rental housing | HUD's coverage rules and firm commitment add a review | For a new building, the months of coverage HUD requires |
What are the steps to get an apartment building loan?
- Package. Gather the documents below.
- Term sheet. Ask which clauses bind once signed; a deposit, cost reimbursement, exclusivity or confidentiality clause can.
- Third-party reports. The lender orders the appraisal, a property condition report and a Phase I environmental site assessment. A buyer isn't protected by the lender's Phase I alone. Ask for a reliance letter or to be named a user of the report, and do your own share of the review, including the cleanup lien search, what you know about the property and whether the price reflects contamination (EPA).
- Underwriting. Get the lender's adjustments to your income and expenses, and ask which limit sets the loan amount. Reconcile the revised proceeds with the equity you'll need.
- Approval. The commitment letter lists approved terms and open conditions; check each against the term sheet.
- Closing. Before signing, check the final loan agreement, guaranty and prepayment terms against the commitment, and tie the settlement statement to net proceeds and required equity. Refinancing owners should order the payoff letter early, since prepayment notice can set the closing date.
What goes in the loan package?
First review: a dated rent roll (tenant, lease dates, rent, concessions, balance owed); trailing twelve-month and prior-year operating statements; occupancy history; the purchase agreement or payoff terms; renovation budget; sources-and-uses schedules for the whole project and for cash due at closing, showing holdbacks and interest reserves apart from purchase proceeds; an ownership chart; and the guarantor's financial statements, real estate schedule and track record.
During underwriting: bank statements, collections reports, sample leases, tax bills, insurance, entity documents and proof of post-closing cash.
How do you reconcile the rent roll and statements?
Use monthly records covering the same months as the statements.
- Start with gross potential rent: every unit, occupied or vacant, at market rent.
- Subtract loss-to-lease (the gap between market rent and in-place lease rent), vacancy and concessions, counting each dollar once.
- List each tenant's balance owed on the rent roll and tie the total to your delinquency report. Show write-offs on their own line, apart from credits and concessions that reduced what a tenant owes.
- Match collections to bank deposits, setting aside timing differences and non-rent receipts like security deposits.
- Explain what still differs, one line each.
How long should you plan for each stage?
Hypothetical example: assumed weeks for a stable building bought with a permanent loan, for planning only.
| Stage | Planned weeks | Needs first | Done when (who) | What delays it |
|---|---|---|---|---|
| Package | Weeks 1-2 | Statements and bank records | Reconciled package (owner) | Books that don't tie to deposits |
| Term sheet | Weeks 2-4 | Same package to each lender | Term sheet picked, binding clauses marked (owner) | Missing items, open clauses |
| Reports | Weeks 4-8 | Signed term sheet, site access | Reports accepted (lender) | Access delays, Phase I findings |
| Underwriting | Weeks 4-9 | Package, report drafts | Final sizing tied to your equity (lender, owner) | Slow answers to lender questions |
| Approval | Weeks 9-10 | Final reports, underwriting done | Written approval with conditions (lender) | Committee conditions or resizing |
| Closing | Weeks 10-12 | Signed commitment; title, survey and insurance ordered in week 4 | Closing checklist cleared (all parties) | Open conditions, payoff letter, insurance |
Under 40 CFR 312.20, a buyer seeking federal cleanup liability protection must have the environmental review done or updated within one year before closing. Five parts must fall within 180 days: interviews with past and present owners, operators and occupants; the cleanup lien search; the government records review; inspections of the property and adjoining properties; and the environmental professional's declaration. If closing slips, have the environmental professional recheck each date. EPA adds that the owner must also comply with continuing obligations after acquiring the property.
How do you test whether the permanent loan will repay the bridge?
Hypothetical example: all figures are assumptions, not market data.
| Uses | Amount | Sources | Amount |
|---|---|---|---|
| Purchase | $10,000,000 | Bridge loan | $8,000,000 |
| Renovation | $1,500,000 | Owner equity | $4,000,000 |
| Closing costs and reserves, including an interest reserve | $500,000 |
Outside the deal, the owner holds $600,000. Bridge interest comes from in-place income and the interest reserve (cash set aside at closing to pay interest). $200,000 of the outside cash covers interest those don't, plus a renovation overrun, leaving $400,000 at maturity.
Net operating income: the example uses cash-basis NOI, collected income minus operating expenses, counted before loan payments, depreciation, income taxes and capital spending. The OCC notes NOI may also deduct reserves for capital replacements (Comptroller's Handbook), so ask for your lender's figure.
Financing assumptions: the lender requires 1.25 coverage (NOI divided by annual principal and interest), a 6.00% rate and 30-year monthly amortization, which gives an annual payment constant (annual principal and interest divided by the original loan amount) of 0.071946063, and caps the loan at 75% of value at a 6.0% capitalization rate.
Formulas: maximum debt service = NOI ÷ 1.25. Loan by coverage = maximum debt service ÷ 0.071946063. Value = NOI ÷ 6.0%. Loan by value = value × 75%. No other sizing limit applies. Math runs at full precision; results are rounded to the nearest $1,000.
| Hypothetical | Base case | NOI 10% lower |
|---|---|---|
| Net operating income | $700,000 | $630,000 |
| Maximum annual debt service | $560,000 | $504,000 |
| Loan by coverage | $7,784,000 | $7,005,000 |
| Value | $11,667,000 | $10,500,000 |
| Loan by value | $8,750,000 | $7,875,000 |
| Permanent loan (lower of the two limits) | $7,784,000 | $7,005,000 |
| Bridge payoff not covered | $216,000 | $995,000 |
| Against $400,000 at maturity | $184,000 left | Short $595,000 |
These are gross proceeds, before permanent-loan closing costs, against a principal-only payoff; in your own test, use the full contractual payoff, including accrued interest. If the downside gap exceeds your cash at maturity, shrink the bridge or add equity before signing. Count only extensions whose tests you meet in the downside case, and check whether the rate cap (protection capping a floating rate) expires first.
Can a HUD 223(f) loan repay an apartment building bridge loan?
It can, but only if the building meets HUD's eligibility and underwriting requirements, the loan is approved, and its net proceeds cover the full bridge payoff before the bridge matures. Coverage history is one of those requirements. HUD's 223(f) program insures mortgages for the purchase or refinancing of existing rental housing. HUD is shown here because it is the bridge exit with the most published rules.
For a newly built one, Mortgagee Letter 2020-03 lets HUD accept an application once construction is complete and expressly supersedes all earlier guidance on time elapsed since construction. HUD's MAP Guide (revised March 19, 2021), section 3.7.2.B, accepts it once the building has held the required coverage for one full month. As of October 5, 2026, HUD's program summary page still says three years.
Ask the HUD lender to document eligibility under current guidance in writing, plus any requirements of its own. These newly built rules and the three-month test below are keyed to construction and the final certificate of occupancy. If you renovated an existing building, as in the example above, ask the HUD lender in writing whether your work brings it under them.
Then get the HUD lender's written schedule for eligibility, underwriting, the qualifying coverage history, firm commitment issuance, remaining closing conditions and expected funding. These overlap. The three-month test below is measured before endorsement, not before application, so it can run while HUD processes the loan. Compare the bridge maturity with the date the HUD loan is expected to fund and deliver the payoff, plus a stated contingency allowance.
- HUD coverage is NOI divided by annual principal, interest and mortgage insurance premium. The example above leaves out the premium, so at the same NOI, rate, coverage ratio, amortization and payment schedule, HUD's test supports a smaller loan. Mortgagee Letter 2025-03, dated January 8, 2025, cut the minimum for market-rate 223(f) loans from 1.176 to 1.15.
- A building submitted within three years of its final certificate of occupancy must hold that coverage for three consecutive months before endorsement (when HUD insures the loan), measured on collected revenue less normalized expenses (section 3.7.2.B).
- Section 4.2.1.5 limits firm commitment extensions to 180 days from issuance, plus 60 calendar days HUD headquarters may approve for good cause at its discretion. These figures limit extensions, measured from issuance.

FAQ
Does an apartment building loan need a full appraisal?
Expect one, ordered by the lender. If the value comes in low, ask for revised proceeds showing every limit; a lower value cuts the loan only when the value limit is the lowest.
How long does an apartment building loan take to close?
Get the lender's written deal schedule at term sheet and work back from your contract's financing deadline or your loan's maturity. The calendar above assumes 12 weeks for a stable purchase, for planning only.
What happens if the Phase I finds a problem?
If the Phase I reports a recognized environmental condition (REC), ask the lender whether it will require a Phase II investigation, a reserve or remediation before closing. Before ordering one, check your contract's due-diligence deadline.
What should I ask each lender so the apartment building loan term sheets compare cleanly?
Ask each to state the amount funded at closing and any later advances or holdbacks, the term, fixed or floating rate (and for floating, the index, margin and floor), any interest-only period, amortization, coverage and leverage limits, cash you must bring, prepayment type and extension tests. On recourse, ask which carve-outs make the guarantor liable for specified losses and which make the whole loan recourse, and what acts, omissions or events trigger each. Then read the final guaranty.
