I think DSCR Loans are definitely in your future as you continue to grow your portfolio but probably not the best fit here:-Can strictly not use DSCR for any property you live in - would technically be possible if you moved out, leased up the unit you are currently in and provided good documentation that its legit - but this is a firm non-starter for DSCR (absolutely no occupying the property)-DSCR Rates at best are in the sixes on a cash-out refinance - so you would be doubling your interest rate at least on the current property - which could make sense but its a pretty high hurdle.

There is a high demand for rentals in all of Columbus.

I used to have a 6/2 on Ohio State university campus north of downtown columbus and I got 1600 a weekend and netted 2500 a month probably. a lot of days were vacant but we did really well all the time for huge groups which is a nice I still recommend and there's not a lot. we just sold a new build for a medium term rental in newark close to intel. there's demand for high quality, well furnished places.
