Wanted the 60 acres across the street and couldn't get it so bought this house on 3 acres instead.

So he must have already bought the duplex or none of these things could be happening.

If you have any tips for me as well that would be much appreciated (just bought my first STR this fall and the quad in the spring will be my first LTR). 

I don't have to adjust to some other PM's way of management.Recently bought some properties in Rumford.

For real estate, I used the P and S agreements for the longest time, but I wanted an easier way for those I bought from.

The second of two homes I bought when I sold the rental, I would have bought a more expensive one as the one I got was close to the university and tended to attract students which had higher turn over (though it may also be my local market).I'd also look up how to do a 1031 (I think that is what it's called, I'm not in the US) where you defer capital gains taxes on rentals by buying another within a set period of time.

I had the same situation last year with a property bought through Rent to Retirement in Detroit. 

I currently have one rental property that I bought this year, spent a large amount of time renovating it, and it’s now rented.

Regarding BRRRR, this is a tough strategy today due to interest rates, if you did a modified BRRRR and bought a property and renovated it and house hacked it that could do very well for you. 

That way you know you're building something the right people want =)On another note, I just bought a STR in Olive Branch that we're about to launch.
