Given your assumptions, you are not going to be able to get enough of a loan to fully cover the rehab, even with a hard money loan, so you'll need to pull in cash from elsewhere.One possibility is to have your mom sell you the house with a personal loan, not one attached to the property. 

Living in one unit and renting out the others allows you to deduct 75% of expenses like mortgage interest, property taxes, insurance, and shared repairs as rental expenses, while the remaining 25% applies to personal use.

Of course most GPs have personally put in money to keep the deals from sinking.

What if someone else passes away and now you needed their signatures? 

@Lauren MerendinoI strongly believe that your chosen market should be somewhere that you can go to in person / have strong personal knowledge of / have family or a network in already.  

I'm still in the learning phase and have read about a hundred different books on FI and personal finance.Looking for any resources that might help me on my way.

If not from the person in office, then definitely from the person running against them.

HELOCs are fine, but keep in mind that you really only want to use 50 percent of less (each) of your available equity just so you aren't creating a problem that you can't solve later if the value of your personal residences fluctuates.If you both have W2 jobs though, have you looked into getting qualified together and just getting a loan, 10 percent down each?

If they've genuinely abandoned, you'll notice their clothing, personal hygiene, and things of value are all gone.

The other PM can be a fix-mindset type of person where they are not willing to share anything unless you have a property and are willing to sign a PM agreement in the same conversation.
