You could spend thousands upgrading an apartment with ceramic tile, hardwood, lighting, etc...

.+ The plumbing work in the bathrooms is done and the floors are prepped for the new ceramic tile to be put in.+ The kitchen plumbing is in progress. 

And I am not thinking maybe it makes sense to put in ceramic wood-look tiles in the first floor (maybe everywhere except wet areas -- so you still have a "two-tone" look).

Depending on how upscale the home is, I would think sinks wouldn't make sense to refinish - I just bought a couple new ceramic sinks for our house and they were $40 each.

Yes...paint and the items you mentioned.Also: Ceramic Tile, thin set, grout, Appliances, cabinets, vanities, lighting, faucets, etc.

I guess I should not have installed ceramic tile in living rooms and bathrooms.

Vinyl Plank Flooring: I haven't tried this product but have heard that the click-together kind is better and this type might require additional adhesive and preparationPorcelain Tile:Porcelain is supposedly better than ceramic.

Haven't priced it out yet but I will probably pay between $2-$2.5k- sink $200, - faucet - $200, - backsplash $300 install, another $300 materials- I usually add canned lights in kitchen ~$80 per,- Flooring: If tile, I buy the $1 per sq ft ceramic so materials are cheap ($150), labor for that may be about $1k for a decent sized kitchen / If I do engineered wood, then about $2.50 per sq ft for materials and $2-$2.25 for installation- Appliances: about $1k, I don't provide fridge, just dishwasher, stove, microwave- Plumbing hook up - ~$250Bathroom:- I have had to demo walls before due to tile, so probably $300-$400 for new drywall if that is the case- Tile shower - probably around $250 for materials and $750 for labor (including cement board installation).

My latest purchase is getting ceramic tile installed in all the baths, foyer, kitchen, and eat In kitchen area.  

I am using Ceramic tile on the floor in kitchen and bath and in the showers.
