If the owner was foreclosed on and isn't being straight with you he might be trying to pocket some money before auction time or the bank taking the home.So, first step is check the county records about deeds, liens, and judgements.

All right I know this is an old thread but I'm going to go ahead and put my two cents in. as a wholesaler I have two answers to this situation the first one being, if it's a new relationship and you've never done a deal with this wholesaler before absolutely not. there's no trust and there's no history. however, if you've closed multiple deals with this person and they have always been honest and they request it in advance not demand. well use your better judgement.

A judge, using her or his judgement, is unlikely to believe that anything you are planning for today, or that you know is going to happen today, is truly unforeseen. 

My wife (against my better judgement) renewed his lease, but we went month to month and we stated that If he gets two notice to quits, he will be evicted regardless.

If you are buying a Search Report from a title company, the title report should list all liens and judgements, including the foreclosure.

When they call realizing they are setting up to have a judgement on their record they will react accordingly.

I think for each investor it's what they feel comfortable with based on the advice of their attorney and accountant and their judgement and growth plan. 

Some of our requirements are:Income needs to be at least 3 times rent - Verify by calling employerNo evictions in past 3 yearsNo pedophilesVerify current living statusAlso do some social media trolling, we have had several times they meet the criteria above but it comes down to a character judgement call.  

Obviously they only partner with reputable course providers, and I don't think they partner with either company you mentioned (no judgement on their credibility, may just be outside the circle.)

lack of experience, tax liens, judgements, mortgage lates, high DTI, a lack of liquidity, and of course, a bad deal.
