Pa1nter said to me recently that a new paint job (a good one) will add substantial value to a house.
Get him to prove it.
I remember hearing an advertisment on the radio a few years ago... put in a new garage door, add up to $10,000 to the value of your house.
Have you ever heard of someone selling some form of home improvement who does not claim it adds value?
It can add a bit, but if the house still has the original 1960 bathroom and kitchen, well it will not add all that much. It certainly helps saleability.
Once again a lot depends on the added value of the improvements to the overall value of the property. If the property with a 1960 original house is worth $800k and someone is likely to bulldoze it and build their dream home, well paint the place and ask $20k more than the other unpainted house down the road on the same land and watch the purchaser buy that one.
Also painting walls is something that people consider doing to get the colour scheme that they want that goes with their furniture etc.
Ever moved into a house you have bought that has been cleaned by the previous owner and then have your missus insist on cleaning the place to her standard?
However renovate the bathroom and kitchen and don't paint the wallls, well you will loose more value than the cost of paint job.
