Is he that bad at screening tenants or is this house a magnet for bad apples and what will it cost to improve enough to attract quality people?  

“It’s a lower cost of living, high quality of life and a great tech ecosystem there.”So, should you rather invest in a unique market that attracts a single type of resident from a single industry who is quick to leave the area?

That said, I would definitely ask the realtor "what sells" in the neighborhood when it comes to things like fixture finishes, carpet color, quality, etc.

Mold sampling (the testing of the specific areas you see mold growth is usually for the toxic molds -- problematic ones) is a type of testing that's different than the general "air-quality" tests. 

Once a broker is doing larger size deals it makes no sense to work on smaller deals for less money when even the same or more time is required due to the quality of the property being less and the buyer tends to be more marginal as they are going after small balance mom and pop commercial.

You want to focus on quality, long-term tenants, so B/B+ areas are going to be your bread and butter.

Tons of free quality meetings, not designed to get newbies' money.The post should have probably been reported.

Got in low and enjoy the appreciation and fast renting to high quality, highly paid families.

If I had to choose, I'd also pick Miami because the quality of life is much better here. 

It allows for high cash flow, the OSI doesn't need to do any rehab or tenant placement, and the seller stays on as the managing Member in the LLC, so they have a vested interest in the quality of the investment.
