If a landlord is in foreclosure and solicitors have been sending letters but the tenant haven't got an official court order stating that the house has been foreclosed on, should tenant still pay rent?  

I have found some sites provide considerable due diligence type information and others treat it like a national security secret. 

I have an ITIN, but no Social Security number as Immigration just delay and delay.

Otherwise I go through after they leave mark up the security despot and send it back. 

3. is it OK to ask a tenant to bring a certified check, as her security deposit ?

If not, he can sell it to you and carry back a note secured by a 2nd deed of trust.

Not sure I'm understanding so I am mistaken please clarify.If the tenants lease is up on the 29th, you don't officially have to do anything.

I was trained in Internet and Network security and that is a classic example of a scam post.
