The loan for a first apartment building depends on one number before any other: how many units it has. Here is how lenders underwrite a first deal, how much cash you really need, and the mistakes that sink first-time buyers.
By Michael McGovern, Founder | 25+ Years in Commercial LendingCommercial Mortgage Connection · Yonkers, NY The short answer
Financing your first apartment building starts with the unit count. A building with two to four units can use residential financing, including an FHA loan if you live in one of the units. Five or more units is a commercial multifamily loan, sized on the property's income rather than your salary: Fannie Mae's small-loan program, for example, caps leverage at 80% of value and requires at least 1.25x debt service coverage. Plan to bring 20% to 30% of the price plus reserves, and experience on the team, even if it is borrowed.
- 2 to 4 units you will live in: FHA's 203(b) program finances about 96.5% of the price for a principal residence.
- 5 or more units, stabilized: bank or portfolio loans, or agency small-loan programs such as Fannie Mae's, for loans up to $9 million.
- 5 or more units that need work: a bridge loan first, then a refinance once the building is stabilized.
- No track record yet: add an experienced partner or a professional property manager before you apply.

2 to 4 units or 5 or more: the line that changes the loan
Lenders sort apartment buildings into two worlds, and the line sits at five units. Up to four units, the property is treated as residential real estate and the loan is underwritten mostly on your personal income and credit. From five units up, it is a commercial multifamily loan, underwritten mostly on the building's own net operating income.
| Feature | 2 to 4 units (residential) | 5 or more units (commercial multifamily) |
|---|---|---|
| What gets underwritten | Your income, credit and debts | The property's income first, then your net worth, liquidity and experience |
| Owner-occupied option | FHA 203(b) for a principal residence, about 96.5% financing | Not applicable; investor loans only |
| Typical programs | FHA and conventional residential mortgages | Bank and portfolio loans, Fannie Mae small loans, HUD 223(f), bridge loans |
| Down payment | As little as 3.5% with FHA if you live there | Commonly 20% to 30%; Fannie Mae small loans cap the loan at 80% of value |
| Key ratio | Debt-to-income | Debt service coverage; Fannie Mae small loans require at least 1.25x |
If your first property has four units or fewer and you plan to live in it, run the residential numbers first. The rest of this guide focuses on buildings with five or more units, where the rules are different.
What lenders look at on a first apartment building
On a building with five or more units, the lender underwrites the property first and you second. Six things decide a first deal.
| Factor | What the lender checks | Where first-time buyers slip |
|---|---|---|
| Net operating income | Trailing 12-month income and expenses, and the current rent roll | Using the seller's projected rents instead of actual numbers |
| Debt service coverage | Net operating income divided by annual debt service | Sizing the loan to the price instead of the income |
| Loan-to-value | The loan amount against the appraised value | Assuming the appraisal will match the purchase price |
| Sponsor strength | Net worth, liquidity after closing and credit for every key principal | Putting every dollar into the down payment |
| Experience | A record of owning or managing similar property, yours or your team's | Planning to self-manage with no history |
| Property condition | Inspection and environmental screening, plus reserves for replacements | Skipping reports to save time or money |
Debt service coverage deserves the most attention. A 1.25x minimum means the building must earn $1.25 of net operating income for every $1.00 of annual loan payments, and that test, not the price, often sets the maximum loan.
Loan-to-value and your credit come next. Our guides explain how lenders set the loan-to-value ratio on apartment loans and how credit scores affect apartment building loan approval.
Loan options for a first apartment building
A first-time buyer usually chooses among five kinds of lenders. The right one depends on the building's condition and size, and on how long you plan to hold it.
| Loan type | Best for | Key terms | Watch for |
|---|---|---|---|
| Bank or credit union loan | Smaller buildings in the lender's own market | Terms vary by bank; personal guarantees are common | Shorter terms and balloon payments |
| Portfolio lender | Unusual files or buyers who own other properties | Loans held on the lender's balance sheet, with more flexible underwriting | Pricing varies widely |
| Fannie Mae Small Mortgage Loan | Existing, stabilized buildings with 5 or more units | Up to $9 million, 5- to 30-year terms, up to 80% of value, at least 1.25x coverage, fixed or variable rate | Needs a stabilized property; yield maintenance or a declining prepayment premium |
| HUD 223(f) | Buying or refinancing an existing building for a long hold | Terms up to 35 years, up to 83.3% of value for market-rate properties, building completed at least 3 years | Slower approval; not for substantial rehabilitation |
| Bridge loan | A building that needs renovation or lease-up | Short term, sized on cost or as-is value, often with an interest reserve | Higher cost; needs a clear refinance plan |
Compare the programs against our apartment building loans page, and if you already own property, ask about portfolio lending. The rate type matters as much as the program: our guide to fixed vs variable rate commercial mortgages explains how prepayment terms can decide it.
How much cash you actually need
The down payment is only the first check. Plan for three buckets: the down payment, closing costs and third-party reports, and reserves the lender or the building will need after closing.
| Down payment | Cash for the down payment | Loan amount | Loan-to-value |
|---|---|---|---|
| 20% | $400,000 | $1,600,000 | 80% |
| 25% | $500,000 | $1,500,000 | 75% |
| 30% | $600,000 | $1,400,000 | 70% |
Coverage can cap the loan below the leverage limit. Say the building's net operating income is $150,000. At a 1.25x minimum, annual debt service can be no more than $120,000. At an example 6.50% rate with 30-year amortization, $120,000 a year supports a loan of about $1,582,000, or 79% of a $2,000,000 price. At an example 7.50% rate, the same income supports only about $1,430,000, or 72% of the price, and you bring the difference in cash. Both rates are illustrations, not quotes.
Reserves come next. Fannie Mae's small-loan term sheet notes that replacement reserves and tax and insurance escrows are typically required on higher-leverage loans. Beyond what the lender holds, keep your own cushion for vacancies and repairs in the first year.
Seven mistakes first-time buyers make
- Underwriting the seller's projected rents. Lenders use the actual rent roll and the trailing 12 months. Build your offer on the same numbers.
- Underestimating operating costs and capital needs. Taxes, insurance, repairs, turnover and big-ticket items such as roofs and boilers arrive on their own schedule, not yours.
- Rushing or skipping inspections. The property condition report and environmental screening protect you as much as the lender.
- Sizing the loan to the price. The income decides the loan. If coverage fails at the price you agreed, renegotiate or bring more equity.
- Choosing a loan that does not fit the plan. A short bridge loan with no refinance plan, or a 10-year fixed rate with heavy prepayment costs on a three-year plan, both cost money.
- Emptying your liquidity. Lenders look at the cash you have left after closing. A buyer with no cushion is a riskier buyer.
- Ignoring local rules. Check rent regulations, registration and inspection requirements before you close; in parts of New York, for example, many older buildings are rent-stabilized.
How to get approved without a track record
Lenders want to know someone on the deal has owned or run a building like this one. If that is not you yet, borrow the experience.
- Add a co-sponsor. An experienced partner who signs on as a key principal can carry the experience requirement.
- Hire a professional manager. A property management company with local apartment experience is a common way to answer the lender's concern.
- Start smaller. A stabilized building in a market you know keeps the equity and the operating risk manageable.
- Bring more equity. A lower loan amount and cash left over after closing both make a first file stronger.
- Get pre-qualified before you make offers. Knowing your likely loan size keeps you from winning a deal you cannot close.
When to wait
If the deal only works with the seller's rents, with no reserves left after closing, or at a rate you cannot lock, wait. A first deal that stretches every limit leaves no room for the first surprise, and there is always a first surprise. The next building will still be there when your numbers, your team or your savings are ready.

First apartment building financing: FAQ
Can I buy an apartment building with no experience?
Yes, but lenders will want experience somewhere on the team. First-time buyers usually qualify by adding an experienced co-sponsor, hiring a professional property manager, bringing more equity or starting with a smaller, stabilized building.
How much do I need to put down on an apartment building?
For five or more units, plan on 20% to 30% of the price, plus closing costs and reserves. Fannie Mae's small-loan program, for example, caps the loan at 80% of value and requires at least 1.25x debt service coverage, and coverage can reduce the loan below that cap. A two-to-four-unit building you live in can qualify for FHA financing of about 96.5%.
Can I use an FHA loan to buy an apartment building?
Only for a one-to-four-unit property that will be your principal residence, under FHA's 203(b) program. A building with five or more units needs a commercial multifamily loan. HUD's 223(f) program covers existing buildings with five or more units, but it follows commercial underwriting and a longer approval process.
What debt service coverage ratio do lenders require for an apartment building?
Many lenders look for at least 1.20x to 1.25x on a stabilized building, meaning $1.20 to $1.25 of net operating income for every $1.00 of annual debt service. Fannie Mae's Small Mortgage Loan Program sets a minimum of 1.25x.
Should my first apartment building be small or large?
Most first-time buyers start with a smaller, stabilized building in a market they know. It keeps the equity requirement manageable and the operating risk visible. A larger or value-add building usually needs experience on the team and a bridge loan with a clear refinance plan.
