Hi Mark,
What is your overall goal? Are you looking for rentals or to flip in Gainesville? It seems like the rental market has taken a big hit due to COVID and UF/Santa Fe classes going online, causing a mass exodus of students, so vacancy rates seem to have increased substantially. There is fairly low inventory of homes under $250K so they are snatched up pretty quickly with multiple offers, but if you're a cash buyer and okay with few contingencies, you still have a good shot of snagging one. With so many jobs going remote this year it seems like families are leaving apts/condos/townhomes in favor of detached SFRs with more space, but I'm sure that's a national trend, not just local to Gainesville.
From what I understand, Alachua County property taxes are the 2nd highest in the state, and will likely always be high, due to the fact that so much of the land around here is owned by the University and hence can't be taxed, so the local government is sustained by taxing the surrounding homeowners. If you are looking into rentals, it is also important to note that there is now a local Landlord Permit Fee required to be paid annually for each unit you own, and the city has a right to inspect your properties to make sure they're being maintained up to code. I no longer have any short-term rentals here, so you'd have to fact check this, but I have also heard rumors of an increase in short-term rental taxes here.
