Small apartment loans are one of those financing categories that awkwardly sit between residential and commercial property lending.
There’s a lot of confusion about what exactly pushes a building into CRE territory. Is a duplex a residential mortgage deal?
Does a 6-unit building need a commercial real estate loan? How about a mixed-use property with four apartments over a retail bay — how do you finance that?
If you’re interested in buying and managing a small apartment and want to know what your financing options are, this is the blog for you. We will look into:
- How lenders classify small apartment buildings
- What types of financing are available
- How can you use private loans and bridge loans for these deals
What counts as a small apartment in lending?
Lenders usually draw the first major line at 4 units.
So, a property with 2 to 4 residential units — duplexes, triplexes, and fourplexes — will often fall under residential mortgage rules.
Because the loan is still tied closely to you as the borrower, the lender will look at your:
- Personal credit
- Debt-to-income ratio
- Income documentation
- Down payment
- Reserves
And if you plan to live in one of the units, you may be able to qualify for owner-occupied financing.
Apartment buildings with 5 or more units usually need commercial multifamily loans.
These buildings are no longer considered borrower-led residential deals, so lenders in this space look at the property’s income more than your personal paycheck.
They will scrutinize the assets:
- Net operating income
- Debt service coverage ratio
- Occupancy
- Rent roll quality
- Expenses
- Overall condition
They will also want to look into your management experience.
What are the options when it comes to small apartment loans?
We’ve prepared the table below to make it easier for you to see what loans are available for the type of small apartment project you’re planning to pursue.
Conventional residential loans for 2–4 units
A conventional residential loan can work well if you need financing for a duplex, triplex, or fourplex.
If you plan to live in one unit, the lender may treat the property as your primary residence rather than a straight investment property, which can make financing easier.
Owner-occupied loans often come with better pricing and lower down payment options.
If you plan to rent out every unit, the lender will see the property as an investment, so they will expect you to have a larger down payment. Interest rates and loan fees also tend to be higher.
Lenders price investment loans this way because they see them as riskier than loans tied to a borrower’s primary home.
Freddie Mac’s conforming guidelines allow up to 75% loan-to-value for a 2- to 4-unit primary residence, but only up to 70% loan-to-value for a 2- to 4-unit investment property.
In plain terms, you may be able to borrow more against the property’s value if you are an owner-occupant than if you were an investor.
Fannie Mae has set separate conforming loan limits for 2-, 3-, and 4-unit properties. In 2026, the baseline limits are:
- $1,066,250 for two units
- $1,288,800 for three units
- 1,601,750 for four units
Fannie Mae small mortgage loans
Fannie Mae and Freddie Mac both have loan programs for smaller apartment buildings, but they mostly want stable properties, not messy turnaround deals.
Fannie Mae small loans are for apartment buildings that are occupied, with rents coming in.
The books have to be clean, and the property itself should be in fairly good condition.
Fannie Mae is not the lender to go to if your building needs a major rehab.
Fannie Mae may finance 5+ unit multifamily properties with
- Loans up to $9 million
- Terms from 5 to 30 years
- Amortization up to 30 years
- Up to 80% LTV,
- Minimum DSCR of 1.25x
Fannie Mae usually wants borrowers (1) to have a net worth at least equal to the loan amount (2) plus enough liquid cash to cover six months of principal and interest.
Freddie Mac small balance loans
Freddie Mac Small Balance Loans also target smaller multifamily properties:
- Loans from $1 million to $7.5 million
- Amortization up to 30 years
- Maximum LTV up to 80% in top and standard markets
Freddie Mac’s DSCR requirements rise as the market tier gets smaller:
- 20x for top markets
- 25x for standard markets
- 30x for small markets
- 40x for very small markets
Freddie Mac small-balance financing may work if you’re buying a stabilized 10-unit or 20-unit apartment building in a larger market.
FHA multifamily loans
The most popular type of loan for small apartment investors is HUD/FHA 223(f), which can finance the purchase or refinance of an existing multifamily property with 5 or more units.
The benefit is that these long-term, fixed-rate, non-recourse loans can stretch up to 35 years, so monthly payments are usually more manageable compared with shorter-term debt.
But HUD loans take months to close and involve a lot more paperwork and third-party reports. It’s not the best choice if you’re trying to buy a 6-unit building and the seller wants to close in 30 days.
But if you already own a stable multifamily property and want to refinance into a longer amortization schedule, FHA multifamily financing is definitely worth looking at.
Private and bridge loans
Private or bridge loans make sense if your property is not ready for long-term financing, but the problem is fixable.
Say you’re buying a 10-unit building that’s not fully leased or stabilized yet.
A bank will likely reject the deal as it looks today because the current rent roll may not support the loan.
But a private lender who understands CRE, like Private Capital Investors, will see the property’s upside and the steps needed to transition it into a financeable asset.
- Is the location strong?
- Are the rents under market?
- Is your plan to repair the units and lease them realistic?
If yes, you may qualify for a bridge loan can help you:
- Buy the building
- Complete the repairs
- Improve the property’s income
You can then refinance into a bank loan, Fannie Mae, Freddie Mac, or HUD financing later when the building achieves stronger occupancy and enough income to pass long-term underwriting.
Private lenders are also more willing to lend even to borrowers who are facing issues that usually cause conventional lenders to hesitate, such as self-employed borrowers whose tax returns don’t show enough qualifying income.

We understand that CRE borrowers don’t always have the luxury of waiting 60 days for agency-style execution or several months for HUD.
