Could be a business decision based on keeping long-term high quality tenants rather than risk the costs on turnover. 

@Cole Bossert I think @Sarah Kensinger and others have touched on the biggest qualities, especially communication.

So, I went hunting.Huntsville, Alabama, caught my attention because it’s a highly educated city with growing industries and a stable, diverse economy, as well as a really high quality of life compared to the surrounding areas. 

The mailers I receive for my properties are not of a high enough quality, to make me believe the sender understands what gets a recipient to even open or read the mailer, let alone respond. 

(Assuming quality of service doesn’t decrease.)No matter how you look at it, that is a ton of money.

@Tove Fox hope you find this copy & paste useful:)-------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

With 30 years of residential construction experience and having built several homes in the past few years, I bring a strong foundation in project execution and quality craftsmanship.Right now, I’m seeking lenders to help me unlock home equity for property acquisitions and to expand my portfolio.

Not the case.Just like everything else, there are always different quality of Section 8 tenants.  

Lots and lots of research.Price points also help, block quality, etc.

The quality of the reports you receive also varies.
