This was my slowest off season since the Great Recession (not counting Covid lock down periods) 2) when building up your reviews you will likely be best served by having a rate below market.  

My first thought was sell to lock in your tax free cap gain.

Also, have you made any significant alterations to the property or if it were put on the market today, would it be indistinguishable from a standard 4-bedoom house (are there any extra walls for the SRO, constructed locks/barriers etc.)If its a standard SFR and the leases are very short term - there is a path that you could refinance this with a DSCR as basically a Short Term Rental and then potentially change strategic course back to SRO if needed at a later date

again, maybe you find something on the MLS that is mispriced, and so it works, but i doubt you'd be able to move fast enough to lock it down, since you're so far away. 

I've set a goal to have something locked in within the next 3 months!

If you are going to go with secured mailboxes you will need to contact your local postal office and tell them you have two new boxes that you will need to get "Arrow" locks installed on.

I would be interested to hear from investors in areas like Arlington or Dallas proper where it has really locked down on STR regulations and hear how their transition to MTR has gone for them. 

If there are multiple doors then I'd just lock it in a way that makes the door unusable 

I make sure that I try not to spend time moving appliances or changing locks.

There is a lot here that he needs go over, such as are you cashing out, looking to lock rate, is there pre pay, do you want community or agency?
