I the property I managed offered to paint 1 room if a tenant had lived there over 2 years, and signed a new lease for 12 months, and we also offered to clean carpets, main traffic areas.We usually painted the main living room or kitchen, and they were required to move items and cover any large items.Our owner felt if was the thing to do and we had over 3000 apartments in the portfolio.

Long story short, they completely stopped paying rent for 2 months, but left peacefully in exchange for a signed document from me to to help them get HUD.Work Done: Trash cleanup and removalNew Carpet and paintDoor and trim installationHardwood floor finishFlea removalPros: Cheap taxesNew roof, water heater, furnanceHardwood floorsBig bedroomsPorchBig basementCons: House takes up entire property, so no landLocation is in a sketchy part of town1 Off street parkingBasement & washer/dryer hookups can only be accessed by walking outsideLessons Learned: Location matters more than the house sometimes.

I'd say I would pay is $500/$1000 to clean and touch-up unit after a tenant vacates (clean carpets, touch up paint, maybe replace a faucet that's been leaky). 10k seems way out of line. 

I bought the place only with intentions of paint, carpet, new fridge and stove.

Be prepared for vacancies and people waiting for you to kick them out.And some I'd say well if you resign that new 12 month lease, I'll be happy to paint that living room and shampoo that carpet for you.. 

With the level of rehab in them, especially the one that rents for $1000/month....if I were to sell them in the next 3-7 years, I am only looking at new carpet and interior paint and can really not worry about Capex spending as it has been rehabbed with all new inside and out etc.  

I had a animal house I will never forget... it was a little zoo on the out side I thought how quant .. knocked on door and there was loud barking from literally 20 to 30 dogs.. and it had cheap lamanite flooring so you could hear all the dogs nails and paws running toward the door.. lady opens the door and you guess it full blown kennel only no dogs were kenneled  .. had to take it to studs to get smell out... seen many homes were they wore out carpet and were living on the sub floor but that's pretty standard in a lot of these... :)   and bought one that was a Porno house big studio and equipment left behind... it was a million dollar home

Repeat with calculations for siding, flooring, carpet, tile, paint, windows, appliances.

Upon each unit vacating, we would spruce up the units, add new flooring and carpet, clean up and bathrooms, and finally upgraded the doorways, hallways, and common area.

Thank you Conn, yes, we just put in new flooring(Home Depot Life Proof)(pulled out the old carpet), painted cabinets(Rustoleum Kit), and replaced all the light fixtures(Home Depot and Amazon), and picked up a SS Stove off of Facebook Market Place ( to finish out the SS Appliance theme ) to bring it up to date.
