Hey @Josh B., @Jaysen Medhurst is totally correct. FHA is awesome for first time home buyers who don't mind paying PMI because it is their home. When it comes to a SFH investment a couple hundred dollars is a big deal.
I am familiar with Utah County and it is exploding right now, but I would count on 3% as well (worse case you're pleasantly surprised?).
Conventional makes getting rid of PMI a lot easier for the borrower. Once you get to that 78-80% LTV, in most cases, you just contact your loan service and they will take it off.
SFH investment is an awesome idea, especially if you're living there with a couple friends who are covering rent. My suggestion would be live there as long as you can while having your friends cover the rent. Once you get to that 80% LTV you gain a lot of flexibility with renting it out to a single family. Hold the property for a long time. SFA investment is a long game, but worth it.
Good luck!
