I hope it will be a long time from now, but I and 2 other siblings are the beneficiaries of a SDIRA (non-Roth) that primarily owns a 300+ acre timberland tract in Virginia with some cash reserves in the account.

Your going to have 2 units and not rent them?  

These days, every MLS syndicates to sites like Zillow and Redfin, so you are likely seeing every house on the MLS on Zillow/Redfin/etc.

I have an accounting degree, and I still outsource my taxes.

I have a 2.5% assumable VA loan with over $520k remaining and the homes price is $785,000.I considered posting in community forums on FB but that’s not allowed.

I don't see a lot and feel like there is spam in some of them. 

Added roof deck and finished basement.

And, I am talking about LOT of investors for tens of millions. 

-Sale my home that I currently live in to fix up the apartment building or-Keep my home and rent it out- use HELOC or-Take out a loan to fixAny advice is appreciated, Thank you!

A well written management contract should clearly spell out what is expected of both the PMC and the owner, to PROTECT both and avoid misunderstandings.
