If they try to hide who their current landlord is or lie about it, you can simply deny them based on that.

Heavy cases of clear cut fraud and flat out lying to their investors. 

How will you know when one is trying to rip you off, is lying to you, or what to do if a squatter moves in? 

Your pretty much on here lying trying to make us look bad same as John did all because you were upset in how your investment went.

If your bottom line is so tight that you are hand-wringing and making forum posts asking about a second colander, the problem lies with you.2.

That process has direct lender involvement.Where the challenge lies, is when unsophisticated "investors" with no experience, no money and no reserves use creative financing (often called wrap, subto, lease option, seller financing, land contract) to purchase properties and along the way there is a "hiccup".

No follow through and constantly lies about progress on your home.

Why are you lying about who you are and hiding from your investors?

That's the problem with lying, right? 

BUT, then you want those landlords to judge every single tenant individually and not lump them all together with the ones that lie, cheat, steal, and destroy the property on purpose?
