I come across a person who has a commercial strip of 7 stores free and clear worth around 2 Mil.

If that doesn't work, you could charge them a reasonable fee for both issues and just let them sue you in small claims court if they think it is worth it.

Are they worth the costs? 

You could build a hotel for $75k a key and it would be worth a $100k a key stablized.

They are typically hardworking, quiet, and keep the place clean.

The average is in the low double digits.Yes, we typically buy and renovate. 

The likelihood of all of these occurring is low in a typical subject-to transaction. 

The monthly rent to purchase price is typically 0.8 percent.As a first step, I was only looking to be able to find better deals which have a nicer rent to price ratio [once the deal is done, a PM company can pick up from there].

Not sure if it would be worth it.  

For example, a 10% return (or reward) can be worth the risk if you are investing in a Class A single-family rental in a great market with an A+ tenant, but not worth the risk at all if betting on a 16-seed to make it to the Final Four in March Madness.Investors in mortgage bonds utilize the risk-and-reward framework when allocating how to invest capital.
