Someone I know also told me a trick to finding good contractors: Go to the local specialty supply houses like plumbing, electrical, etc. 

So, the housing market with its historically low rates looks amazing and that transient work-force I mentioned seems to indicate that the supply of decent renters is high.

Do people buy homes with community water supply?

Other rooms in general can be supplied with 15 amp breakers with a few exceptions.  

It's definitely one way to do it, but you should be prepared for higher vacancy and you should make sure that the area has a good supply of the tenant base that you're looking for in order to get those higher rents.A better approach is likely phasing the increase in over 2-3 years, adding a little bit to the rent each year. 

Obviously we didn't try and charge them for paint and supplies, but when I did hours and hours of work for cat odor mitigation, I was not very pleased to charge them $0.00 for my work (of note: I ended up having to hire an odor mitigation company to fumigate the entire duplex).

After all we are still in a global pandemic.

They will want to see a track record of performance with cash flowing global financial statements. 

The main subject area I am talking about is obtaining Hard Money as an option to fund BRRRR for those who do not have an ample supply of cash on hand.

With longer than 30 day stays, you avoid TOT, turnover, less work and restock of supplies etc that you find with an STR.
