I have a lot of buyers looking to house-hack as well, seems to be a popular option with rent increasing across the board in STL. I closed on 2 deals last year with FHA, and you are at a significant disadvantage using it, and Im not being shy about telling my buyers that. The secondary appraisal for the FHA loan can generate significant work before close, especially for multifamilies which have been slightly neglected for years. (read, most of the multis in STL) We even had higher offers passed over for conventional or cash offers.
That said, there are a few programs out there for first time home buyers that I am pointing people at:
A local STL credit union has a first time buyers program that works for up to 4 units. 0% down and covered closing costs in exchange for a slightly higher APR for the length of the loan. This is my first stop for house hackers.
One of my lending partners has a 5% down conventional product, but it has a home ownership course you have to attend to qualify. Still, 5% down is better than 15%.
Finally, you could shop around for a Hard Money Partner to help buy it in cash. This is not ideal, but would give you the cash advantage. Then quickly refinance out of the hard money using a deferred finance option. The goal would be to find a hard money guy who doesn't do points, just rate/term. Rare, but they do exist. This is by far the worst/most expensive/most complicated option, but you are looking for options, right?
I don't want to get flagged for promotion, so feel free to reach out and I can connect you with the programs.
