House hacking is the most practical way I know to get into Central Iowa real estate without a huge pile of cash — and it can absolutely work in Johnston. But Johnston is a higher-priced, established market, so the approach looks different here than it does in the newer cities. Here's how it actually works, and what to watch.
You buy a property as an owner-occupant, move in, and rent out part of it. Because you live there, you qualify for owner-occupant financing — which is far cheaper to get into than an investor loan. The rent you collect offsets your housing payment, so you're building equity and cutting your own cost of living at the same time.
In lower-priced markets, house hackers often buy a duplex and rent the other side. Johnston's inventory skews toward single-family homes in an upper-middle price tier, and true duplexes are scarce. So the house hack that pencils here is usually a larger single-family home with rentable space — a finished basement with its own entrance, a bonus suite, or spare bedrooms you rent to roommates while you live in the home.
Johnston has real advantages for this: steady rental demand anchored by major employers like John Deere Des Moines Works and Pioneer (Corteva), a low-turnover market where quality homes hold value, and a school-district reputation that keeps demand strong. The trade-off is price — with median sale prices running $375K–$500K, your entry point is higher, so the numbers deserve extra scrutiny.
With an FHA loan on an owner-occupied home, your down payment can be as low as 3.5%. On a $425,000 Johnston home, that's roughly $14,875 down instead of the 20%+ an investor would need. You live in the home; the rent from a finished basement or a roommate or two goes toward your payment. In the right deal, that rent covers a meaningful share of the mortgage — which is what makes house hacking worth the effort on a first purchase.
These are illustrative numbers, not a guarantee. Every deal has to pencil on its own — rents, condition, and the payment all matter, and Johnston's higher price points mean the margin for error is thinner.
I'll be straight with you: house hacking is real work, not passive income. You're a live-in landlord, which means tenant or roommate screening, maintenance, and the occasional inconvenient phone call. The numbers have to clear on their own merit, and I never promise a return. Talk to a local lender early about FHA terms, owner-occupancy requirements, and whether rental income from a basement or roommates can count toward your qualification, and make sure the property meets FHA condition standards.

Johnston's higher prices don't rule out house hacking — they just change the play. Buy a single-family home with rentable space, use owner-occupant financing, run the numbers honestly, and do the work. In the right deal, it can be one of the smartest first moves you make in an established, high-demand market.
