Our home was in that state in mid 2020 when the guy bought it, rehabbed it and sold it to us. It's a brand new house from the brick walls in. I think he put about $130,000-170,000 into it with everything he did. He had a crew who did everything. We have a dugout, finished basement, main floor and second floor. 3BR, 3.5 bath. Fenced back patio (concrete) with everything new to code. Tore off formstone, tuck pointed, the brick, added a 2-story addition onto the back of the home. Basically he did the classic East Bmore Flip that's happening on every street around us.

I will say he had a tougher time then because he was doing this during the pandemic while the housing market was insane. So getting appliances and materials was really difficult for him. He actually did everything right structurally and mechanically with better-than-contractor-grade finishing spec'd throughout. My father is an engineer and has been a home inspector for 30+ years and said this place is a lot better than most of the flips he's seen.

So, ours was probably on the upper end of that range. I'd guess $155-170k for the total renovation.
