Anyone have tips on how to put together some sort of packet to bring to him so that he knows this is a legit option and to help him see the benefits of this?

Could my parents deduct it on their taxes, or would it only be on my end (schedule E)?

A buddy of mine Patrick runs the new investor subgroup of the AZREIA (Arizona Real Estate Investors Association).Next meet up for that group is May 7th at 6pm in the Keller Williams building located at:1745 E.

The purpose of line 2 on schedule E is to determine the split between rental and personal.

Any tips and tricks to approach them, provide meaningful value for them and building rapport? 

@Daniel DietzGood tips to know up front, thanks!

I'm usually tipped off because they also pay the rent late.Here is a learning point:  I did have one instance where a tenant was current with their bills but shutoff utilities anyway. 

Any tips on good resources for calculating comps and rehab expenses?

Thanks in advance for all tips, tricks, and advice. 

Thanks for pointing this out, @Stanley Nguyen.I will check this issue.I did not sign up in their portal, I filled registration forms and sent them via e-mail.Have you tried that?
