It's fine to have people leave their info and reason to sell on your website, however this becomes very impersonal and off putting to some who you really need to call and build a "friendship" with before they open up.

For the friendships which we buy with a price, and do not gain by greatness and nobility of character, though they be fairly earned are not made good, but fail us when we have occasion to use them."-- Niccolò Machiavelli

It's a business, not a friendship.

You can't treat this business as a friendship.  

Do you have a lot of experience with him either in business or just in a general friendship?

I have had long discussions with large E and O companies before about their stats.In property management your friend might be okay in the beginning but if something goes wrong the owner and the tenant turn on the PM very quickly as the scapegoat.It sounds like to me this isn't worth the hassle of the small coin or something going wrong and souring a friendship.

Seek their respect, not their friendship.

This isn't a friendship, we aren't buddies, I expect respect and for you to pay rent on time. 

very familiar, but first figure out exactly what you are trying to accomplish. .....on a side note..just friendship?

I hope we can connect and build RE partnerships- and friendships- that last!
