Qualifying Wholesaling Single Family Homes that are Rented. How?

[Joshua Howaniec]

I am working with an investor in Speedway Indiana who wants to sell off several properties of his. All are single family. Most of them are rented so I can't go inside and take pics, but why would I need to if this is clearly a  play for a buy and hold investor?

That said, what are some questions you would ask about mortagage, equity, contracts with tenants, whatever. What would you want to know about these homes if you were going to wholesale a rented single family unit to an investor?

I cant treat it like a flip. So what is the best way to go about it?
