As @jayhinrichs indicates, rarely if any does this occur. 

Historical data is not indicative of future returns, but there is precedence that it did happen. 

(b) The existence of any fact or circumstance or suspicion of the existence of any fact or circumstance that indicates a property might be or is psychologically impacted is not a material fact that must be disclosed in a real property transaction.

This is a good question and as others have indicated, there is no correct, universal answer. 

This month, my property manager informed me that when she spoke to the tenant he indicated that he paid rent for March and April to the previous owner. 

I try not to make anyone layout any money until I know for sure that I have no red flags otherwise that indicate that I would not accept them as a tenant.

The article seems to imply that skin color indicates a connection and does not point to causality.

Will give you an indication of any deferred maintenance you'll have to deal with.

Even had to check a special box on the return indicating that it was a "related party" 1031, and I thought that of itself might attract a little additional scrutiny, but now that we are past the 6 year statue of limitations, that's no longer really an issue either. 

Is it an indication that the rent is too low?
