Kitchen Cabinets are all real wood in good shape that I would paint, put on new hardware, new sink, and new countertop.

Without question, go with a stainless steel sink....SELF rimming (not with the separate trim ring) and be sure to caulk it well, all the way around to prevent water to seep back under the edge and delaminate (or rot) the cut edge of the countertop.

New countertops.

What material are you using for the countertops?

What they don't care about: type of countertops, kitchen cabinets, brand of appliances, massive bathrooms, paint colors (so long as they're reasonable), age of house (other than reasonably weatherized so utilities are cheap). 

Me and my partner who are splitting the Purchase and Rehab costs have a 20K rehab budget; which we believe is enough for laminate, carpet, paint, new countertops, tubs, appliances and probably a new roof if we do the work ourselves (we are handy and going to take measurements to confirm budget).

LOTS of reasons:- Stains the walls and ceilings when people smoke inside- Gets inside the carpeting and makes the house smell bad -- really gets into curtains and furniture too- Can make burn holes in carpets- People put them on the counter tops and they wind up causing stains/burn marks- People flush them down the toilet and it causes clogs- Butts litter the ground around the house because smokers seem to think littering butts is okay (when did just throwing a used butt out your car window or anywhere outside on the ground become "okay"???)

The college kids around UTC are open to living in not as desirable areas, compared to the UTK kids that want granite countertops in their apartments. 

I had one Appraisor who was very impressed that I used high quality materials-he got this impression because I had granite countertops and double hung windows.

Raised the entire soffit above the kitchen, adjusted the layout and finished with new hardware, tile backsplash & Quartz countertops.
