I would just add that probate isn't really a painful process in most situations.

Make sure it explicitly explains the process for termination if you are unhappy with their services, especially if they violate the terms of your agreement.3.

I would love to hear from other more experienced in the field about alternative ways to financing that I should consider besides the HELOC, maybe also hear from investors on how the process of bringing investors onboard works.

Leaving out auction and foreclosure costs for a second, when you write that check for $220k the trustee is going to pay BigBadBank the $175k they are owed first, then he's going to pay LittleBadBank the remaining $45k, and you will get a clean title as the process is going to wipe the slate clean.

We started the eviction process.

I was in the process of about to get into the real estate world of investing until this occurred.

Follow the lease and the laws in your state and start the eviction process.

I'm still in the process of growing my portfolio, but have heard others 1031 all their smaller properties into a larger building and have a property management company manage, OR, set up a seller financing deal with another buyer that gives you the cash flow you desire.
