I was searching through the expired listings in my area this weekend, and yep, lots of weird paint colors on the interior walls. I actually love some of the daring reds people are putting on their walls, but lots of folks just don't have the guts or the furnishings to make it work. Let's face it, power paint jobs are great if you like them, but get over it when you put your home on the market.
If you don't feel like painting over the color, with the 2 coats of primer and 2 coats of new color; a buyer won't either. I think you just reduce the chances of "grabbing" the interest of a buyer who wants to put their own "color scheme" to their new home.
In my job, I've heard this a number of times "I love that color, I'm so proud of it, lots of people comment on my wall. Ok, but are they buying your house? I have a good friend who is a power painter, I loved her red wall but not her aqua blue bathroom or her aqua green master bedroom. I grabbed her by the shoulders and shook her, gently of course and with love, and told her "we can't put this house on the market until you paint". She really thought I had insulted her artistic talent and creative energy and wanted to go ahead and make a few but not all of the changes. Guess what everyone kept saying that looked at or showed the house! "Wow, these people really love their paint". Keep in mind, most people don't think about the "paint job" when they look at a house, only that it looks good if it's one they want to buy!
Another dear friend heard me when I said I loved the paint job, but it has to go before we put the home on the market. "Oh I love that red wall, but ok, I'll fix it with a neutral tan". Her home sold in 7 days. Need I say more!
