, kitchen rehab generally cost ??

My wife had already remodeled the kitchen, and after we got married, we spent some time to clean it up and do a full bathroom remodel. 

You are already doing kitchen and bathroom remodeling in your flips.

Remodeling bedrooms, bathrooms, living room, kitchen and patio

Unfortunately one of the issues was a major issue like fixing the kitchen hardwood floor which will take substantial time and money.

New roof, new well, new septic, full gut renovation on two of the three bathrooms, new kitchen (cabinets, appliances, fixtures, counters), new exterior doors, and solid oak floors throughout.

We completely remodeled the home, updated kitchen bathrooms, floors, roof, mechancial, electrical and plumbing.

Tile or Vinyl plank flooring in kitchen and bathrooms?

You also need all kitchen stuff, towels, sheets, etc. 

Now there are some improvements (kitchen remodel, bathroom remodel, upgrading windows) where that flips on its head, but it's still something to really plan through.
