With that, I've got a great method for analyzing the FLOOR of STRs in the Tampa Bay area but to capture the true average or ceiling I have found to be more difficult to obtain through many experiments.

You can also install light fixtures instead of ceiling fans if they happen to damage those as well.

Repairing a ceiling fan costs the same whether a home is $100,000 or $400,000...so the expense % is a little higher. 

Under the floors, in the walls, in the ceilings, in the yard, etc.Those little bitty things turn a profit into at best break even and many times a loss.I remember doing things thinking wow almost 80% there and then that last 20% the finishing work takes a long time!

Definitely reason to pause, but if the inspection says there is no mold and that the floor and walls/ceiling are dry (this is important that the walls/ceiling are dry), then it may very well be an old problem. 

There are currently zero holes in the living room ceiling, but if I go with recessed, how many are typical or cost-effective?

They provide a ceiling for maximum interest rate costs.HOWEVER, it will cost you.

I would have scrapped the popcorn ceilings, and gone stainless appliances....but since he didn't have to do any of this I'm OK with it!

The tables show ceilings with ALL utilities included. 

Ceiling heights may also determine your outcome.
