Goor roof, refinished hardwood floor on first floor, kitchen remodeled in last 5 yrs., the only thing it really needed was carpeting upstairs-not a big deal.

my personal experience with rehabs generally range from ten to twenty thousand based on the quality of materials you use example. ceramic to lynolium tile generic or name brand paint carpet to hardwood floors etc.

But I'm not refinishing the hardwood floors.  

Worst of all the hard wood cherry cabinets in both the kitchen and bathroom have scratches and one cabinet door has been partially ripped from the hinge. 

Strip the home and put in hardwood floors, new kitchen, bathrooms and new double pane windows.

Example, I have an old timey craftsman I have which is in a more residential and nicer neighborhood than a couple others, with not as much closeby-- but is very cute (but small) place with lush yard, old timey hardwood, and more charm, etc, it is really killing the game, moreso than the stuff that is in more traditionally "good" MTR locations. 

Ceramic Tile; Allure; or Hardwood floors is the way to go.

I just acquired a three unit and the first floor apartment has all original hardwood floors.

@David Chung not all wood floor is hardwood, some is softer like  fir, pine.

Our tenants want white appliances and so do we, so that is our standard.You may find that tenants want hardwood floors, but often are not willing to do the upkeep to preserve them and prevent scratches.
