If a house has ugly walls (ugly yellow), should I repaint?

[Dale Viljoen]

So I am busy looking at a property in what I believe is a high capital growth area. Its garden and driveway is quite the mess and the exterior walls might need a paint as well but one thing I have not seen many people talk about is weather painting the interior walls a nice white color will increase the value more then the costs of the paint/labor?

All help is appreciated.

We had a new tenant insist on yellow walls. In fact they offered to buy it & paint. Then they wanted bright ocean blue in one bedroom to complete a Surfside painting on the wall. We had just rehabbed the unit all new drywall primed in white BUT we complied & they are still there 6 years later. I KNOW when they vacate it will be back to a more conducive bland color.
