Never ever send a signed copy of a lease to these leaseing companies. 1)Make a copy of your signed lease 2) write DO NOT FILE with a bold pen in BIG letters on each page. 3) When you receive the funds ( Bank Wire or cashiers check ) deliver the Orginal signed lease… I have done this several ways… An in-person meeting, Wired funds, UPS overnight letter etc. … If you send them the lease - send it US Postal Certified, UPS traceable, FedX and email the Trace number to the lessee… The problem is if you deliver the lease without getting funds – many times they will just try and “FLIP” the lease, and will 1) pay you when they re-sell it 2) not pay you if they can’t resell it. And if they file the lease you will have to get a release from them --if they don’t pay you-- before any other lesee will deal with you for a new lease… Don’t get into that mess – have cash in the bank before you give them them lease!!!
