House hacking with an FHA loan: the 3.5%-down path I used

How a near-broke former van-dweller bought a $470,000 building with $16,450.

The single biggest thing standing between most people and real estate is the down payment. The reason I own a duplex today is that I found the door with the lowest bar to clear: an FHA loan on an owner-occupied small multi. Here’s exactly how it works.

The headline: 3.5% down

FHA loans let an owner-occupant buy a 1–4 unit property with as little as 3.5% down. On my $470,000 duplex, that was $16,450, not $94,000, which is what a 20% conventional down payment would’ve cost. The seller covered closing costs, so my total cash to close was about $16,450.

That’s the whole magic trick. A small multi, financed like a home, because you’re going to live in one of the units.

The rules you have to follow

FHA’s gift comes with conditions. The big ones:

• You must live there. Owner-occupied means you move in (generally within 60 days) and stay at least a year. This isn’t a loophole for absentee investors, it’s a deal because you live in it.
• 1–4 units only. Duplex, triplex, fourplex. Five or more units is commercial financing, a different world.
• The self-sufficiency test (3–4 units). For triplexes and fourplexes, FHA requires the property’s rents to cover the payment. Duplexes are exempt, which is part of why a duplex is the friendliest starting point.
• Mortgage insurance. This is the cost of the low down payment, and it’s real.

The catch: MIP is permanent

On an FHA loan with less than 10% down, you pay a monthly mortgage insurance premium (MIP), mine is about $312/month, and on FHA loans it generally lasts the life of the loan. There’s also a one-time upfront premium (1.75%) you can roll into the balance.

I want to be straight about this: that $312 a month is annoying, and over years it adds up. But the alternative was waiting years to save a 20% conventional down payment while prices climbed faster than I could save. For me, the MIP was the right trade, it bought me time in the market I couldn’t otherwise afford. When you build enough equity, you can refinance out of FHA into a conventional loan and drop it.

Why this beats waiting

A lot of people decide to “save up and do it right” with 20% down. In a rising market, that often means renting for five extra years and buying a smaller asset later. FHA let me start with $16,450 and let the building, and my tenants — do the rest.

Run a real listing through the calculator with 3.5% down and today’s rates. The MIP is in there. So is the reason the deal still works.
