If you are raising the rent I'd make sure its cut and dry and is at the end of their lease term, I wouldn't trust that notarization tid bit you got from someone else, if the lease is signed and executed its likely valid through the full term.

The only way you could get to 3 quality STRs with that $80,000 is if you use the BRRRR method and execute it absolutely perfectly. and get all of your capital back + some extra to cover furnishing on every deal.

You need to have criteria designed to protect your money, and a reliable method of determining value.In my opinion, appraisals are not necessarily a reliable method of determining value, so staying within your own market area to start with can also protect your capital because it's easier to know value next door than across the country.

House hacking may not be for you, but every method involves risk, expense and discomfort.
