I moved to Columbus a few years ago (from Portland, Oregon which was super expensive) to become a full time real estate investor, and ever since, I've completed quite a lot of BRRRRs, flips, and own a successful rental portfolio here in Columbus Ohio.

Then you should turnover the other unit and move into it so you can rehab that side.

If you go MTM and she moves out in December too bad.

Throughout my research over the past 6 months I've learned about creative financing which intrigues me and is something I would need to learn about moving forward to scale my portfolio. 

promissory notes are pretty generic.. but you usually have a PN and the PG is a separate document.

As rent has become more expensive more households are coupling via roommates, moving in with a partner, etc.

I’m a born and raised Austinite, went to college in Denton and graduated in 2016 then moved back home.

For me, I would just wait as a buyer until it falls out of contract then go in and buy it, or call the agent and be like "hey you know its a wholesaler who has it under agreement".... or simply put in a back up offer  I instruct my clients to do this all the time.. many times they move into first position when the first buyer flakes.. back up offers are the way to go.. in this situation.

Now, since the rates are up, the rush to move to FL is down and local tenants are pushed to city suburbs and settled there due to better prices, there is a lot of available inventory.

That statement alone will cause you to move too quickly and take too much leverage which minimizes those solid investments you already have.Ask yourself, why do you want to scale faster?
