I am making efforts to increase my network in the area & develop relationships with buyers who are spending time & money on acquiring majority off market deals & have spoken to them about keeping me in mind if they are looking to sell something they just acquired without having to do any work on it for profit as this method should still be a better deal than buying that property through the MLS if it popped up there.

That's a lot different than buyers you have talked to and/or built a relationship with.

*This post does not create an attorney-client or CPA-Client relationship.

As you mentioned with your relationship point, when you are growing faster than you can handle, you will quickly take on more risk than you realize.  

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.
