My own rental portfolio started with a house hack, and the loan that makes house hacking possible for most first-time buyers is the FHA loan. It lets you buy a 2–4 unit property with a small down payment, as long as you live in one of the units. Here’s how it works in Pennsylvania, and what I tell every client before we start touring duplexes.
What Is an FHA Loan?
An FHA loan is a mortgage insured by the Federal Housing Administration. Because the government insures the lender against loss, FHA loans allow lower down payments and more flexible credit than most conventional loans. The big advantage for house hackers is that FHA treats a 1–4 unit property the same way: you can buy a duplex, triplex or fourplex with the same low down payment as a single-family home.
FHA Requirements for a Multifamily Property
- Down payment: 3.5% with a credit score of 580 or higher; 10% with scores from 500 to 579. Many lenders set their own higher minimums.
- Owner occupancy: you must move into one of the units, typically within 60 days of closing, and intend to live there for at least a year.
- Mortgage insurance: an upfront premium of 1.75% of the loan (usually rolled into the loan) plus an annual premium paid monthly.
- Loan limits: FHA sets maximum loan amounts by county, and the limits are higher for 2-, 3- and 4-unit properties. Check the current limit for the county you’re buying in.
- Reserves: for 3–4 unit properties, lenders require cash reserves, commonly three months of mortgage payments, after closing.
Using Rental Income to Qualify
This is where house hacking gets powerful. Lenders can usually count about 75% of the market rent from the units you won’t live in as income. The 25% haircut covers vacancy and maintenance. On a duplex where the other unit rents for $1,600, that can add roughly $1,200 a month to your qualifying income, which can make the difference between qualifying and not.
For triplexes and fourplexes, FHA adds one more hurdle: the self-sufficiency test. I break that down in detail in The FHA Self-Sufficiency Test Explained.
FHA vs. Conventional vs. VA for House Hacking
| Loan | Minimum down (2–4 units) | Key notes |
|---|---|---|
| FHA | 3.5% | Flexible credit; mortgage insurance for most of the loan life; self-sufficiency test on 3–4 units |
| Conventional | 5% (owner-occupied 2–4 units) | Usually needs stronger credit; mortgage insurance can be removed later |
| VA | 0% | For eligible veterans and service members; no monthly mortgage insurance |
The right choice depends on your credit, savings and long-term plans. I connect clients with lenders who close these loans regularly, because not every loan officer knows how to handle rental income on a multifamily.
The FHA Appraisal: Where Duplex Deals Fall Apart
FHA appraisers check that a property meets minimum property standards for safety, security and soundness. On older Philadelphia and Bucks County duplexes, these are the items I see most often:
- Peeling or chipping paint on homes built before 1978 (a lead-paint concern)
- Missing handrails, broken windows or trip hazards
- Exposed wiring, missing outlet covers or electrical hazards
- Roofs near the end of their life or active leaks
- Utilities not turned on at inspection
- Units that may not be legal or permitted
As an electrical engineer, I look at the panel, service size and wiring during the first showing. If a property won’t pass an FHA appraisal, it’s better to know before you’re under contract, so we can negotiate repairs or move on.
My Advice Before You Make an Offer
- Get pre-approved with a lender who regularly does FHA multifamily loans.
- Verify current rents and leases, and estimate realistic market rents.
- Budget for repairs, maintenance and vacancy, not just the mortgage.
- Confirm each unit is legal with the township or the City of Philadelphia.
- Ask the seller for credits toward closing costs; FHA allows seller concessions up to 6% of the price.
Frequently Asked Questions
Can I use an FHA loan to buy a fourplex?
Yes. FHA loans can be used for 1–4 unit properties as long as you live in one of the units. Triplexes and fourplexes must also pass the FHA self-sufficiency test.
How much do I need to put down on a duplex with FHA?
As little as 3.5% of the purchase price with a credit score of 580 or higher, plus closing costs. Sellers can contribute up to 6% toward closing costs.
Can I rent out my whole FHA property after a year?
Generally, yes. FHA requires you to occupy the property for at least a year. After that, many owners move out and keep the property as a rental. Talk to your lender about your specific situation.
Does FHA count rental income from the other units?
Usually. Lenders typically count about 75% of market rent from the non-owner units toward your qualifying income.
