Broadly speaking I agree with the idea that you can't let tenants mistake their relationship with you.

With a preference for multi-family, I am looking to learn as much as possible while simultaneously building as many relationships as possible.

It’s easy when you already have that relationship established.

Also you can not advertise a 506(b) in any way, you have to have a pre-existing relationship with anyone you present it to.

Yes, but also make sure you or your property managers build a relationship with the assistance office.  

Use this time to build relationships with the brokers.

I secured my money however nothing beats having a healthy relationship with your borrower, helps yo sleep at night.

If you have a relationship with an agent to title rep you can find out address by address, but it is a tax so you can also find it and its maturity date via the La tax portal.  

If that is of interest  I would recommend establishing relationships with one or two folks who have decent track records.  

I would lawyer up as rallying homeowners is likely going to be hard since you never built any relationships from not living there, but it could be that others are just as frustrated and this Stay At Home order is making people more willing to spend their day differently.
