Thanks for your response and input.

I've come to this as my standard practice:1)  Pull all students on the lease jointly and severally liable for to TOTAL amount. 2)  Include a co-signer/financial responsibility form for parents of each student. 

Hey Chris,Thanks for the response!

@Ray Lai my list was filtered to multi family owners in a couple specific zip codes that had owned for over seven years or more years.I have done a very similar mailing with same contents/criteria but used a paid mailer and the results were less than 1% response with 0 deals.
