The financial statements can tell you far more than many realize but hey can also hide a lot if misrepresented.

Buying a new entity and trying to hide that there has been significant change in the ownership and management of that entity, basically making an application for financing as "another" entity is simply fraud!

When I see situations where someone is trying to limit the due diligence it is usually to hide something.

Seller(s) also agree to sign an affidavit at closing personally guaranteeing the validity of all leases and rentledgers.Now that may seem like a lot for a seller to agree to, but if they have nothing to hide, why would they not agree?

On the rent issue the other problem is that owners have learned it it a long process and if they just hide they can stay 9 months up to  3 years I have seen rent free.  

So they can be missed if a tenant moved here and hides that they lived in another state a few years ago.

Good point above on hiding imperfections with a thicker product though.

I'm just curious as to why you are supposed to hide that you are the House owner or it's bad to live in that home?

And I kind of have no idea of what am I hiding for?

Not much advice for remediation since I was mostly on the "ID and Investigate" side of site contamination, but there is probably a deal hiding there if you can protect yourself adequately.One thing I do know is if it was a gas station in the 1950's and before, it TOTALLY had leaks!!!
