I structured the notes for Habitat for Humanity affiliates obtaining opinions.

Transactions with Affiliates.

(No business affiliation - just a really happy customer)

If you've searched me here on BP, you know that I'm a Renatus affiliate.

Other things one can do is subscribe to the local paper and business journal, bookmark the chamber website, call Real Estate agents and Property Managers not affiliated with the sell, talk to other out of state investors for their feedback, just to name a few.  

Trusts or LLCs or other entities can have ownership or affiliate relationships, for example, a Trust could own an LLC. 

I'm not affiliated with them just a happy customer.

You need to find a way to become an insider.Your referral source already has established relationships with real estate industry professionals, perhaps thru legal groups; perhaps thru social networks and affiliation. 

If not, it wouldn't hurt to mail something to that address and it will be forwarded to whomever is affiliated with the property.

I'm pretty sure that Bigger Pockets has an affiliation with an online legal partner and I am sure they are good and you can get a discount by using your Bigger Pockets membership.
