Buying a 2-4 Family in MA With as Little as 3.5% Down

Two and three families are everywhere in this part of the state. Drive through Lawrence, Lynn, or the older sections of Haverhill and Methuen and you'll see block after block of them. A lot of first-time buyers walk past those listings because they assume a multifamily means 20 or 25 percent down. That's true if you're buying it as a rental. It isn't true if you're going to live in one of the units.

Owner-occupied 2-4 unit financing has gotten noticeably better in the last couple of years, and it's one of the more common conversations I have with buyers who are getting priced out of single families. Here's how it actually works.

The two main low down payment routes

FHA allows 3.5% down on a 2, 3, or 4 unit property as long as you occupy one of the units. That's been true for a long time. You move in within 60 days of closing and you're expected to live there at least a year.

Conventional financing changed in late 2023. Fannie Mae dropped the minimum down payment on owner-occupied 2-4 units to 5%. Before that, a triple decker needed 15 to 25 percent down on conventional, which is why FHA was basically the only game in town. Now you have a real choice, and the choice matters more than people expect.

The short version of the tradeoff: FHA is more forgiving on credit and debt ratios, but if you put 3.5% down on a 30-year FHA loan, the mortgage insurance stays on for the life of the loan. Your only exit is a refinance. Conventional at 5% down carries PMI too, but that comes off once you've built enough equity, and on a multifamily in a market where rents are rising, you can get there faster than you'd think. Conventional also has stricter credit requirements and doesn't bend as much on debt-to-income.

Loan limits are the other piece. Both FHA and conforming limits go up for each additional unit, so a three family gets a meaningfully higher limit than a single family in the same town. Those limits change every year and vary by county, and Essex County limits are not the same as Rockingham County in New Hampshire or the counties in Maine, Florida, or Connecticut. Look up the current figures on the FHFA site for conforming and HUD's lookup tool for FHA rather than trusting a number you read in an article.

The self-sufficiency test, which is where three family deals die

This is the single biggest thing FHA buyers don't know about, and it catches people after they've already gone under agreement.

On FHA loans for 3 and 4 unit properties, the property has to pass a self-sufficiency test. The appraiser estimates fair market rent for all the units. You take 75% of that total, and it has to cover the entire monthly mortgage payment, meaning principal, interest, taxes, insurance, and mortgage insurance. If 75% of the rents doesn't cover the payment, the deal doesn't work on FHA. Period. It doesn't matter how strong your income is.

Two families are not subject to this test. Three and four units are.

In practice, this is where high-priced triple deckers fall apart. A three family in Lynn or Lawrence with three modest apartments and a purchase price that's climbed faster than the rents often won't pass, especially with today's tax and insurance costs baked in. Conventional has no self-sufficiency test, which is a big reason the 5% down conventional option is worth a serious look on 3-4 units even when FHA would be easier on paper.

If you're targeting three families, get the rent picture reviewed early. I've had to move buyers from FHA to conventional mid-deal over this, and it's a lot smoother when we've already priced out both paths before the offer goes in.

How lenders count the rent

You generally get credit for the rent from the units you're not living in, which is what makes the payment manageable. Both FHA and conventional apply a vacancy factor, typically counting about 75% of the gross rent, so a $2,000 unit helps your qualifying picture by roughly $1,500 a month, not the full amount.

Where the rent number comes from depends on the situation. If the unit has a lease in place, that lease matters. If it's vacant, or if you're planning to raise a below-market rent, the appraiser's opinion of market rent drives it. The appraisal on a 2-4 unit includes a rent schedule, which is why the appraisal on these takes longer and costs more than a single family. Budget for that.

One thing worth knowing: an inherited tenant comes with an inherited rent. If the seller has a long-term tenant paying $1,100 for a unit that would rent for $1,900, you're buying that $1,100. Massachusetts tenancy rules are not something you can shrug off, and a tenant at will with no lease still has real protections. Read the leases before you commit.

Reserves and the costs people forget

FHA wants three months of payments in reserve on 3-4 unit properties. Conventional reserve requirements on 2-4 units vary by the automated underwriting decision and can run six months on the larger ones. That's cash you need to document after closing costs and down payment, so factor it in before you decide what you can afford.

Then there are the costs that don't show up on a single family worksheet:

• Insurance on a 2-4 unit is a landlord policy, not a homeowner policy, and it prices higher. Older triple deckers with knob and tube wiring or an ancient roof can be genuinely hard to insure. Get quotes during your inspection period, not the week before closing.
• Water and sewer bills in the older Merrimack Valley housing stock are often a single meter for the whole building, which means you're paying the tenants' water unless the leases say otherwise.
• Heating systems. Separate heat per unit is worth real money. One boiler heating three apartments means you're paying to heat your tenants.
• Vacancy and repairs. A furnace replacement in a three family is the same furnace as anywhere else, but now you have two or three of them.

If the property needs work

A lot of the small multifamily inventory around Haverhill and Lawrence needs something. FHA's Limited 203(k) lets you finance renovation costs into the purchase loan, and HUD raised that cap to $75,000 as of November 2024, up from the old $35,000 ceiling. That's a much more useful number than it used to be for roofs, kitchens, heating systems, and electrical updates. The Standard 203(k) handles bigger structural projects.

Worth flagging for Massachusetts buyers specifically: if the building was constructed before 1978 and a child under six will live there, state lead law puts deleading obligations on the owner. On a rental unit, that's your responsibility as landlord, not something you can defer. It's a real cost on older properties and it's better to price it during the offer stage.

If you're not going to live in it

Everything above assumes owner occupancy. If you're buying a 2-4 unit purely as an investment, you're looking at 20 to 25 percent down on conventional, or a DSCR loan, where the underwriting looks at the property's rent versus the payment instead of your tax returns. DSCR is often the answer for investors who are self-employed or already carry several properties, and it's how a lot of the investor purchases I close in Lynn and Haverhill get done. Rates and down payments are higher than owner-occupied. That's the tradeoff for not having to qualify on personal income.

Before you start looking

Get a real preapproval that specifically contemplates a multifamily, run both FHA and conventional numbers so you know which one your target price range actually supports, and if 3-4 units are on your list, understand the self-sufficiency math before you write an offer. Ask your agent for the actual leases and the last twelve months of utility bills as part of your due diligence.

And keep the sequencing in mind. The rent from the other units helps you qualify, but the reserves, insurance, and appraisal costs all hit before you collect a dollar of it.
