Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

I manage hundreds of rentals and have had thousands of tenants, but I've never been sued once.

There are thousands of red flags.

The GC is likely at least a couple of more thousand dollars.  

Quote from @Stacy Banks: Hello I wanted to know what does it cost to do foundation & framing for a 1,500sq ft house being built in Lehigh Acres Florida.  

The cost to remove just one illegal will be in the thousands and way the government operates probably 100's of thousands of dollars. 

i also help with the set up, hosting and finding cleaners  I make it a one stop shop and the process makes it seamless and a sure thing with making money and keeping costs down.  

Agree it is difficult to assess costs when they vary so much by location.Keep in mind that some turnovers are sickenly expensive, and that is just the nature of the business. 

If it costs you thousands to refinance it needs to be worth it. 

If operating costs increase, then customers/tenants will eat the costs in tight markets.
