I apologize ahead of time for the long post but heres my situation...I am renting a single family home and I have accepted an application fee and screened a couple (recommended approval from SmartMove) who are relocating from out of state.

Screen Screen Screen the tenants.

I've looked at all of the tenant screening services called out on this site and find it difficult to sign up or pay for a credit report only.

All you have to do is go to the "learn" tab at the top of your screen and read the articles, and also just search BP for some of the keywords you used in your post.It's not going to be "easy" or "hard" to find cash-buyers, it's going to depend on how you do it.

Establish your screening criteria now, and write it down/document it.

I was wondering what criteria you savvy BP investors use to screen the buyers? 

You choose which property you want, which lender to use, which contractor will fix it up, where the rehab materials will be bought from, what the finished product will look like, how to screen the tenants and who the tenants will be, how much cash flow you will make, and on and on.

Have found great tips for screening potential renters on this site and look forward to using them.  

That's why  it is so important to do a good job of screening ANY AND ALL tenants!!
