House Hacking in the Twin Cities: How I Bought My First Duplex (And How You Can Too)

My first property wasn't actually a house hack. I bought a single-family home in 2014, a "For Sale by Owner" listing I found on Craigslist. Negotiating that deal and fixing the place up myself taught me a ton, but it was just a place to live not an intentional investment at the time.

It wasn't until 2021 that I did my first house hack, when my wife and I bought a duplex on the east side of St. Paul. We moved into one unit, rented out the other, and let someone else's rent cover all of our mortgage. This is house hacking, and it's still one of the smartest ways to build real estate wealth, especially here in the Twin Cities.

What house hacking actually is

House hacking means buying a property, living in part of it, and renting out the rest. Most commonly that's a duplex, triplex, or fourplex, though it can also mean renting spare bedrooms in a single-family home. The core idea is the same either way: you occupy the property, so you qualify for owner-occupied financing, but you're still generating rental income like an investor. It also gets you started on actually managing a rental property and handling tenants.

That combination is the whole point. It's the one strategy that lets you buy like a homeowner and build wealth like an investor at the same time.

Why the financing makes such a big difference

If you buy a pure investment property, one you don't live in, most lenders want 20 to 25 percent down. That's a steep barrier for a first purchase.

But if you live in one unit of a 2 to 4 unit property, you can often qualify for the same low down payment programs available to any homeowner such as a 3.5% down FHA loan, or a 5% down conventional. That can mean putting far less down than a traditional investment purchase would require, while still collecting rent from the other units.

That gap, low down payment financing on a property that also produces income, is what makes house hacking so different from a regular first home purchase. You're not just buying a place to live. You're buying your first rental property and getting owner-occupant terms to do it.

How the math tends to work

Every deal is different, so I won't pretend there's a universal formula. But the basic shape looks like this: you take on a mortgage sized for a multi-unit property, then rent covers some or all of your monthly payment. Depending on the property and the rents in that area, your actual out-of-pocket housing cost can drop dramatically, sometimes to close to zero.

That's the appeal. You're still building equity and still getting the tax benefits of ownership, but your monthly cost of living can be a fraction of what renting the same space would cost you.

What to look for in a house hacking property

A few things I always tell people to pay attention to:

• Separate utility metering. Shared meters mean you're either covering your tenant's utilities or dealing with a messy split every month.

• Layout that actually separates the units. You want real privacy, for you and for your tenant. Up down duplexes are most common, but side by side layouts are the most desirable.

• A location that works for both you and a renter. Somewhere you'd want to live, and somewhere someone else would want to rent.

• Realistic rent numbers. Don't assume the top of the market. Look at what similar units are actually renting for right now. Shoot for the mid-range conservatively on your rents and make sure the deal still works with those numbers.

Common mistakes I see

The biggest one is treating the first year like it's supposed to be perfect. It won't be. You'll deal with a maintenance call at an inconvenient time, or a tenant who's a little more work than you hoped. That's normal, not a sign you made a mistake. But you also need to treat it like a business. This isn't a casual hobby, start putting your processes and best practices in place. This is the best time to start working on your systems.

The second is underestimating how much living next to your tenant changes the relationship. Living in the building makes you more hands-on than a typical landlord, which is usually a good thing early on, but it's worth going in with eyes open.

Thirdly, many people also get caught up with wanting the numbers to cover their living expenses completely. This was much easier to do while prices and rates were lower, so I like to recommend comparing to regular living expenses or renting, rather than trying to live for free. This will be a much better expectation and give you more options.

Frequently asked questions

Do I need real estate experience to house hack? No. I'd already bought one home by the time I did my first house hack, but that's it, no investing background. The owner-occupied financing is designed for exactly this situation, someone buying a multi-unit property to live in themselves.

How many units can I buy with owner-occupied financing? Generally up to four units, as long as you live in one of them. Above four units, you're typically into commercial financing instead.

Do I have to live there forever? No. Most owner-occupied loans just require you to live there for a set period, often around a year, after which you're free to move on and keep the property as a straight rental if you want.

Is this only for people early in their career? Not at all. I still use this same thinking on bigger deals today, just at a larger scale. The principle doesn't change: let income-producing property carry more of the cost.
