It would be mostly cosmetic, i.e. paint touch up, cleaning carpets, etc.

Just to give an idea the property is a 3/2/1, 1,900sqft, liens are about $91,000(+ $150 daily), property is trashed but really needs clean up & a kitchen and paint.

Minor repairs would include replacing screens, some paint, etc.

Doors and door frames Some windows Ceiling in basement Kitchen and bathroom floors (new tiles or laminate) LOTS of paint, indoor and outdoor All new kitchen appliances Some drywall repairs but nothing extensive Bathroom tile, shower, faucets, vanity All new light fixtures Some vent repairs and new vent covers.

You'll need to do the floors and paint.

Browsing through some upstate homes and I came across something really cheap and this caught my eye:https://www.hubzu.com/property/000103207767-239-Steuben-Street-Painted-Post-NY-14870and the last photo (shown above) has some terrible photoshopping skills applied to what could be a gaping hole in the wall.

If one house needs paint and carpet and another one needs a full gut rehab for the kitchens and baths how can a fixed percentage for rehab cost have any basis is reality?

Paint, or frame, or other construction trade.

Maybe just paint.

Exterior should be scraped and painted or vinyl sided, Some plaster repair needed in both apts.
