A multi family property mortgage is a loan on a building with two to four units, and the program you qualify for depends mostly on whether you will live in one of the units. Live there, and you can access low-down-payment options such as FHA and VA, with part of the rent counting toward approval. Buy it purely as an investment, and you face higher down payments, higher rates, and different underwriting. This article covers how financing works for duplexes, triplexes, and fourplexes, what down payment and credit you need, how rental income is counted, and what the math looks like on a Virginia purchase.

Where 2-4 Units End and Commercial Loans Begin
Residential mortgage rules cover properties with one to four units. A duplex, triplex, or fourplex is financed with the same families of products as a single-family home: conventional, FHA, and VA. Once a building has five or more units, it moves to commercial underwriting, where the property’s income and the borrower’s business profile drive terms that differ from residential loans. As of 2026, that line is how both Fannie Mae and HUD define their residential programs, but confirm against current guidance before you write an offer.
The most common mistake is assuming a fourplex needs a commercial loan. It does not. A four-unit building can be financed with a standard residential mortgage, often at better pricing than a five-unit building would get.
The second dividing line is occupancy, and it drives rate, down payment, and reserves more than any other factor. An owner-occupant intends to live in one of the units as a primary residence, typically for at least a year. Buying a multi-unit and living in one unit while renting the others is often called house hacking. A buyer who will not live in the property is an investor, and the loan is priced as an investment property.
A few terms you will see throughout this article:
- DSCR (debt service coverage ratio): the property’s rent divided by its monthly housing payment. Investor loans that qualify on DSCR look at the building’s cash flow rather than your personal income.
- Reserves: liquid funds left after closing, usually counted in months of payments. Multi-unit and investment purchases generally require more reserves than a single-family primary residence.
- Self-sufficiency test: an FHA rule for three- and four-unit properties, covered in the next section.
- Rent schedule: the appraiser’s opinion of market rent for each unit, used to support qualifying income.
Loan Programs for a Multi Family Property Mortgage on Duplexes, Triplexes, and Fourplexes
FHA. As of 2026, FHA allows a down payment as low as 3.5% on a one- to four-unit home when you occupy one unit and meet the credit score guidelines (generally 580 or higher for the minimum down payment). On three- and four-unit properties, HUD applies a self-sufficiency test: the net rental income, after a vacancy reduction, must cover the full monthly mortgage payment. Check HUD’s Section 203(b) page for the current rule.
VA. Eligible veterans and service members can buy a two- to four-unit property with no down payment through the VA loan program, as long as the borrower occupies one unit. Eligibility, entitlement, and funding fee details are on VA.gov.
Conventional. Owner-occupied two- to four-unit purchases generally require a larger down payment than a single-family home, and the requirement rises with unit count. Under standard Fannie Mae guidelines, expect roughly 15% down on two units and 25% on three or four, though some low-down-payment conventional programs differ. Verify current figures in the Fannie Mae Selling Guide, and check county loan limits, which are higher for multi-unit properties, on the FHFA conforming loan limit page.
DSCR and investor loans. If you will not live in the building, a DSCR loan qualifies you on the property’s cash flow instead of tax returns and pay stubs. Expect larger down payments, higher rates than owner-occupied loans, and reserve requirements.
Champions Funding Ally program. For self-employed borrowers or anyone with income that does not show well on a tax return, Duane Buziak originates the Champions Funding Ally program directly. It is a CDFI-certified, no-ratio Non-QM option, meaning approval does not rest on a debt-to-income calculation. These loans are generally aimed at investment and business-purpose scenarios, and terms depend on the property and borrower, so eligibility is confirmed case by case. This program is not affiliated with Ally Bank.
How Lenders Count Rental Income to Qualify You
When you occupy one unit of a multi-unit property, rent from the other units can be counted toward qualifying, but not dollar for dollar. Underwriters apply a vacancy and expense reduction, and the commonly used figure is 75% of the documented rent. The exact percentage and documentation rules vary by program, so they should be confirmed in the Fannie Mae Selling Guide and HUD Handbook 4000.1 for your specific loan.
The documentation depends on the situation:
- Existing leases: signed leases for the units you will not occupy, ideally current ones.
- Appraisal rent schedule: for purchases, the appraiser provides a market rent opinion on each unit. Underwriters often use it when leases are missing or out of date.
- Proof of payment history: bank statements showing rent deposits support the leases.
- Tax returns: if you already own rental property, your returns show how that income has performed.
The investment-property case works differently. When you will not live in the building, the appraiser’s market rent schedule is the starting point, and in a DSCR loan the entire qualification rests on whether that rent covers the payment with room to spare.
The mistake to avoid is expecting 100% of the rent to count. If a unit rents for $1,600, plan on roughly $1,200 helping you qualify, not the full amount. Rent also does not reduce the payment you actually owe each month. It changes the debt-to-income ratio the underwriter sees, while the real cash flow still depends on vacancy, repairs, and turnover.
One more point for first-time landlords: a borrower with no landlord history can still use projected rent in many owner-occupied scenarios, but some programs ask for documented reserves or experience before counting it. Raise this early so the right program is chosen from the start.
Worked Example: Buying a Virginia Duplex
This is an illustration, not a quote. Suppose you buy a $450,000 duplex in Virginia, live in one unit, and rent the other for $1,600 a month. Assume a 6.5% rate on a 30-year fixed loan (an assumption for October 2026, not a current offer), property taxes at roughly 1% of price ($375 a month), and insurance at $200 a month. For debt-to-income purposes, assume gross monthly income of $8,000 and no other debts.
FHA, 3.5% down
Down payment: $15,750. Base loan: $434,250. Adding the 1.75% upfront mortgage insurance premium ($7,599) gives a loan of about $441,849, with principal and interest near $2,793. Adding an annual mortgage insurance premium of 0.55% (about $199 a month), taxes, and insurance brings the total to roughly $3,567 a month. Counting 75% of the $1,600 rent ($1,200) leaves $2,367 for qualifying, or 29.6% of income, versus 44.6% with no rent counted.
Conventional, 15% down
Down payment: $67,500. Loan: $382,500, with principal and interest near $2,418. Assuming private mortgage insurance of about $128 a month, the total is roughly $3,120. After the $1,200 rent credit, the qualifying payment is $1,920, or 24.0% of income.
DSCR investor loan, 25% down
If you do not live there, assume both units rent for $1,600 and the investor rate is 7.25%. Down payment: $112,500. Loan: $337,500, with principal and interest near $2,302. Adding taxes and insurance gives about $2,877. Rent of $3,200 divided by $2,877 is a DSCR of roughly 1.11, which clears the 1.0 threshold many programs require, though pricing is better at higher ratios.
The tradeoff is plain: FHA needs the least cash, conventional costs less each month, and the DSCR route is for buyers who will not live there. For a local benchmark on the rent assumption, compare the $1,600 figure against median gross rent for your county in U.S. Census Bureau QuickFacts for Virginia, since rents vary widely between Northern Virginia, Richmond, and Hampton Roads.
Multi Family Loan Comparison Table: Programs and Providers
The table summarizes the main options. Figures reflect general guidelines as of 2026 and vary by borrower, property, and unit count.
| Program | Minimum down payment | Occupancy requirement | Income documentation | Best fit |
|---|---|---|---|---|
| FHA | 3.5% (2-4 units) | Owner-occupied | Full documentation; rent counted at a reduced share; self-sufficiency test on 3-4 units | First-time house hackers with limited cash |
| VA | 0% for eligible borrowers | Owner-occupied (one unit) | Full documentation; entitlement required | Veterans and service members |
| Conventional, owner-occupied | Commonly about 15% (2 units), 25% (3-4 units) | Owner-occupied | Full documentation; rent credit with lease or appraisal schedule | Buyers with stronger credit and more cash |
| DSCR investor | Commonly 20-25% or more | Non-owner-occupied | Property cash flow rather than personal income | Investors building a rental portfolio |
| Champions Funding Ally No-Ratio | Varies by scenario | Generally investment or business-purpose | No debt-to-income ratio; no-ratio Non-QM | Self-employed or non-traditional income borrowers |
Provider type matters as much as program. Rocket, Movement, and Ally Bank are single-company providers, each with its own guidelines, pricing, and appetite for 2-4 unit properties, so confirm directly with each whether it offers the program you need. Duane Buziak is an independent broker who shops hundreds of lenders at one time, which lets a duplex or fourplex scenario be matched to the program that fits it rather than the one a single company happens to sell. The Mortgage Ally by Duane Buziak is not affiliated with Ally Bank.
Getting Pre-Qualified Without Hurting Your Credit
The sequence matters because multi-unit files have more moving parts than a single-family purchase.
- Soft credit pull review. Duane Buziak uses NoTouch Credit Pull, so the first look at your credit is a soft credit pull mortgage review. Unlike a hard inquiry, it does not appear as an application for new credit and does not lower your score.
- Document checklist. Pay stubs or tax returns, bank statements, and, if you own rentals, current leases.
- Property-specific questions. Unit count, whether you will occupy a unit, current rents, and condition of the building.
- Full application. Submitted only when you have a property under contract or are ready to move, since this is when a hard inquiry occurs.
If you already own a multi-unit and want cash out, some programs allow cash-out refinances up to 90% of value. Limits depend on occupancy and program, and investment properties generally carry tighter limits than owner-occupied ones, so treat 90% as a ceiling for specific scenarios, not a promise.
Closing timelines on 2-4 unit purchases run longer when the paperwork is not prepared in advance. Order the appraisal with a rent schedule early, since it is the document underwriters rely on for rental income. Get insurance quotes for multi-unit coverage before you commit, because premiums can differ from single-family policies and change your payment. Finally, document reserves: the more units, the more months of payments a program is likely to ask you to show.
Multi Family Mortgage Questions, Answered
Do I need a commercial loan to buy a fourplex?
No. Properties with one to four units are financed with residential loans. Commercial underwriting begins at five units.
What is the minimum down payment on a duplex?
As of 2026, it can be 0% with VA, 3.5% with FHA when you live in one unit, and commonly around 15% for a standard conventional owner-occupied duplex. Investment purchases typically need 20-25% or more.
Does all the rental income count toward qualifying?
No. Underwriters usually count a reduced share, commonly 75%, and require leases or an appraisal rent schedule.
Can I get mortgage pre approval without a hard pull?
Yes. Duane Buziak starts with a soft credit review through NoTouch Credit Pull, so the first step does not affect your score.
Is The Mortgage Ally by Duane Buziak affiliated with Ally Bank?
No. The Mortgage Ally by Duane Buziak is an independent mortgage broker and has no affiliation with Ally Bank.
What is the difference between an independent broker and a bank?
A bank offers its own loan products under its own guidelines. A broker such as Duane Buziak compares many wholesale options and matches your occupancy, unit count, and income to the one that fits.
Do Rocket, Movement, or Ally Bank offer 2-4 unit financing?
Each sets its own guidelines and they change, so confirm directly with the company. A broker can compare multiple sources on a single scenario instead.
What is the Champions Funding Ally program?
It is a CDFI-certified, no-ratio Non-QM program that Duane Buziak originates directly, designed for self-employed or non-traditional income borrowers. It is not connected to Ally Bank, and eligibility is confirmed case by case.
Occupancy and Unit Count Decide the Program
Two facts settle most multi-unit decisions. Whether you live in the building, along with the number of units, determines whether FHA, VA, conventional, or DSCR is on the table. Rent then helps you qualify only to the extent it is documented, and rarely at 100% of face value.
