If you are selling or re-mortgaging your property. You might want to sell it for the highest price possible. There are many ways to add value. Such as refurbishing kitchen, bathroom or extensions etc.
However, these projects are not cheap and it is a lot of hassle.
From my research as a Decorator and a Property investor, the cheapest way to gain return on investment is simply adding fresh lick of paint.
Just by adding a fresh neutral paint can bump up the value by 5%.
5% of 500k is 25k!
The reason investors buy tired looking house is because it is simple as that. Fresh paint/new carpet and it is ready for sell.
It is far wiser to spend your money on small changes to make big returns.
