People will buy small multi-family at break even all day in Utah/Saltlake County so it's really competitive and if you aren't financially prepared for initial expenses and no/low cashflow it might break the bank. Values went up 20-30 percent in the last 12 months so people are shooting to make money on appreciation rather than cashflow. It can still work out super well, but it's a bet, and if you're spending your last dollar, you're in a less stable position than your competition.
If you want cashflow in Utah (as in more than $200/month), vacation/short-term rentals, treating an ADU like a duplex, or renting by the room have better margins.
They all have limitations.
Vacation rental laws are dicey in some areas, you'd need to furnish it, and management could (at least initially) be way more hands-on.
The ADU/duplex idea is tantalizing (they could be 100k cheaper and yield higher rent than a legal technical duplex), but it's always illegal (when not owner occupied and properly licensed) and cities have a really big stick they can shake at you if your neighbors complain. If you get caught in year 10, then maybe you've already made money, but if it happens in year 1 (at the same time you just spent 50k on rehabs and your furnace goes out), then you're in the hole and have no way to get out. Also, if something really bad happens (house burns down, tenant gets electrocuted and dies) things will be much worse for you when it comes out that the setup was sketchy and didn't have any official stamp on it. If you want to try it just know the risks.
Renting by the room could be super lucrative (especially in cities with housing shortages and young, single people), but also flirts with illegality. Provo, Orem, and Salt Lake have a "3 unrelated persons" max tenant limit per unit. It's totally insane. That means a 7 bedroom house is allowed, you guessed it, 3 tenants. Everywhere else is 4. Elsewhere (like Seattle, Meridian Idaho, or Bend Oregon) you can have 8, 10, or unlimited tenants, but nowhere in Utah. Point is, your best bet would be something with a really low price point (like a condo) so that you can still cashflow with 4 tenants.
Potentially other niches exist where you can win big, but there are a lot of people watching this market. If you have an unfair advantage, use it. If you want to try to solve a hard problem, do it. Otherwise, you can still build tons of wealth through debt paydown, tax breaks, and appreciation on small multifamily, even if it "only" breaks even on cashflow. Just pick a good property that will last, in a city where things are moving up (and be prepared to pay over asking and waive contingencies).
PS. Lots of cities are adding their first big apartment complexes, so if you can get invited to that party (even as a limited partner), that's something municipal governments really want to make happen right now with us running out of land and having big housing shortages.
