6 Things to Know Before Your First Househack

House hacking is one of the smartest ways to get into real estate. The basic idea is simple: buy a small multi-family property, live in one unit, and let your tenants help cover your mortgage. But before you dive in, there are a few things worth knowing.

‍

1. You Can Get In With As Little As 3.5% Down

One of the biggest misconceptions about buying a multi-family property is that you need a massive down payment. With an FHA loan, you can purchase a property with up to four units for as little as 3.5% down, as long as you live in one of them. That's a game-changer compared to the 20-25% typically required for a straight investment property purchase. For a $800,000 two-family in New York, that's the difference between needing $28,000 and needing $160,000 to get started.

2. Your Tenants' Rent Can Help You Qualify

Here's something even some first-time buyers don't realize: lenders will often count a portion of the projected rental income from the other units toward your qualifying income. That means the property essentially helps you buy itself. If the numbers on the building are strong, you may be able to qualify for significantly more than you could on your salary alone.

3. You'll Get a Much Better Interest Rate Than an Investor Would

Because you're living in the property, lenders treat it as a primary residence rather than an investment. That distinction matters enormously. Owner-occupant mortgage rates are noticeably lower than investment property rates, which can translate to hundreds of dollars in savings every single month. You're essentially getting investor-level access to a rental property at homeowner pricing.

‍

4. You Have to Actually Live There for at Least a Year

This is the rule that catches people off guard. FHA and most owner-occupant loan programs require you to occupy the property as your primary residence for a minimum of 12 months. This isn't optional fine print. Misrepresenting your intent to occupy is considered mortgage fraud. The good news is that after that 12-month period, you can move out, rent your unit, and the favorable financing stays in place. You don't need to refinance.

5. The Rental Income Is Taxable, But So Are Your Deductions

Once you start collecting rent, that income is reportable. But the tax picture is more nuanced than it sounds. You can deduct mortgage interest, repairs, and property management costs on the rental portion of your building. You can also depreciate the rental units over 27.5 years, which is a powerful paper loss that can offset your rental income significantly. It's worth sitting down with a CPA before your first tenant signs a lease.

6. This Can Be Your First Step Toward a Larger Portfolio

Many serious real estate investors got their start exactly this way. After satisfying the occupancy requirement and building equity, some house hackers use a strategy called BRRRR, which stands for Buy, Rehab, Rent, Refinance, Repeat. The equity you build in your first property can eventually be pulled out through a cash-out refinance and recycled into your next purchase. What starts as a way to reduce your living expenses can quietly become the foundation of a real estate portfolio.

House hacking isn't for everyone, but for the right buyer it's one of the most efficient wealth-building tools available.
