While making sure my position in the near-term is well-fortified against near-term threats that can stop me from realizing the bounty that I believe is inevitable as we march into the future.I look forward to being told I'm crazy.

I would agree with @Michael Smythe - the only way a seller comes around to a sub to transaction is when they have no other options or are uninformed.

Ideally if we played the cards right we would have option to take some of the init you do  Equity out after adding value.Thanks for the help!

This creates a negative initial position.

And buying the other one with maximum leverage.This can be especially beneficial to you if the short-term rental you want to buy is positioned such that you could take advantage of a 2nd home loan. 

We suddenly had 2 homes and began exploring what our options were and that is when we discovered the intriguing world of REI and tapped into Bigger Pockets and Better Life Tribe, etc. to begin our education.In the time since his death and the probate process we have been paying his mortgage off and selling items from the home which we have been maintaining.

When you plan to move out will your portion of the "rent" and the other unit create enough positive cash flow.

If you log on to some of the popular sites like furnishedfinder or Airbnb you will see that they have "rent by the room" options.

I would also be well versed in creative financing options to maximize opportunities.For MLS listings, target homes that have been listed for 60-90 days.

Also hearing about FHA, but does not seem to be an option with our lenders, have found 10% down, but not FHA.
