In this scenario does it make sense to buy a triplex or 4plex in a less desirable/up-and-coming neighborhood , rent all units out while I continue to rent in center city/fishtown/UCity/NoLibs? 

Have you considered purchasing another 2-4 unit property to move into and house hack?

We are now upon April 2024, and at the rate things have been going, still have a ways to go (finish ducting for forced hot air, insulation, sheet rock, paint, flooring, kitchens, bathrooms, finishes, and anything I am missing to bring the units to whole).

But yes you're right, one unit is rented out currently so I could work on some rehab in the vacant units and do things as I go on the other.But no, I was not aware those type of DSCR loans were available.

Fannie/Freddie do NOT allow:Texas Section 50(a)(6) Loan Security PropertyA Texas Section 50(a)(6) loan must be secured by a single-unit principal residence constituting the borrower’s homestead under Texas law.

So here we are 5 years in with 4 rental properties working with buyers and sellers most and looking to find partners for building small multifamily buildings, duplexes, triplexes, quads, rent them out, refinance and reapeat, buy land, build the unit, rent, refinance, repeat so we got a BLBURRR.

There are lots of SFH and MF units coming on sale but they don't seem to have a positive cashflow.

A handful of duplexes and a handful of 5+ unit properties utilizing a variety of creative financing solutions. 

What are the top 5 zip codes in Columbus, OH with the highest rental cash flow, lowest turnover/vacancies, lowest crime rates, great schools, and great employers for residential 2-4 unit single-family home neighborhoods?

I own ~80-90 units near USC.
