I’m unfamiliar with them  but these aren’t exactly short term, from what I saw these are tenants.

Short-term? 

Higher upfront costs should lead to lower claims losses. 

Any advice for having an apartment manager who is kind of aggressive or maybe even short tempered would be helpful.

I’d like to start in short term rentals on the gulf coast.

My long term goal is have a few short term rental properties and I’m trying to decide what’s the best next thing to do with my money.

It doesn't take that long to fully analyze a market (notice I wrote market, not property), so why waste your time using a tool that leads you nowhere.

Just wondering if this is allowable especially if I meet the requirements for short term rental requirement for tax purposes like 100 hours?

Other ideas to increase gross rents: Can you change up your strategy and do a short term or mid term rental?
