@Eric Stugart Factors like overall property cost, down payment, quality tenant should be characteristics to look into as well.

I have found, at least in my market, that I get a better quality of applicant and if tenants know there is no "man" to screw over they will be happy to pay rent even in times of black swan events. 

They are not quality control.   

About how much to replace it with good quality shingles?

. - My concern with building new, is not being able to spend all day onsite to manage. only being able to go on site at the end of the day after work to see what was completed and to what quality. 

We plan to do this by turning units with high quality finishes along with increasing curb appeal and making it a more desirable place to live.

I didn’t know any better and just used cheap Home Depot quality cabinets, until I got a recommendation to buy from them.  

Most of my quality applicants come through Zillow and the 10/week for listings is well worth it.  

I find Facebook brings below average interest and quality.
