I travel a lot so I listen to a lot of audio books.

I own a 3/2.5 condo just outside Universal Studios in Orlando.

The other unit is a cozy studio and we’ve had much higher turnover there but they’ve all been great. 

Studio (occupied), 2 bed 2 bath and 3 bed 2 bath both vacant.

I typically like the smaller studio / 2 bed units for STR to avoid parties but I do have a luxury rental in SWFL with all the amenities for a baller stay. 

I would look near Trillith studios in Fayetteville, as it’s out in the boonies, nicer, and might lack competition keep in mind your target market makes $15/hr when looking at price points

I’m looking to buy a 1,115 square foot Philadelphia row home that has already been converted into 3 studio units.

I've met with 80+ builders in our market and only three can build with their GC fee at less than $160 per sq ft. so let's back into your largest you can build and say you find one of three builders in your market and have perfect execution. that's tough to get, most will do $180 a sq ft hard cost no permitting but let's say you do it even better. 180000 / 160 is 1125 sq ft. now personally as developer I'd make that 3 studios and make a ton of money but if you want comfort, you don't have a lot.

We've had it since 2020 and have been renting the front two water view units as STRs and the rear studio as MTR.
