multi-unit house hacking

[Curtis Maag]

In Columbus, OH.  Next step in my business plan is house hack, either a 3 unit or 4 unit...ideally finding one that is distressed, buy at a discount and then rehab before moving in.  I was leaning towards a 4 unit, but a GC just told me that 4 unit is considered commercial and therefore requires 2x the time and cost for permits, and the city will scrutinize any rehab much closer than a 3 unit...just overall more expensive per door.   The other thought is if buying a turnkey instead, does a 4 unit make more sense then.  I appreciate your insight!
