I am constently viewing houses where well meaning owners have put their hard work and money into their houses in ways that they will be unlikely to see a good return off of.
Some of the most common mistakes include: you absolutely must have 4 bedrooms minimum. Do not build your dream house with 2 bedrooms. Do not put bedrooms in the basement, even if they are really nice and have their own baths, they don't count. Basements are for play rooms and gyms. Don't build a luxury house and then skip on appliances or countertops. Don't put in a new kitchen (at any price range) and then get a refrig that doesnt fit in the space and sticks out from the rest of the cabinets by 4 inches.It makes buyers think you skimped on everything. Don't do ANY faux painting or paint any dark colors on the walls. In fact, if you have anything with a faux marble finish, paint over it immediately. Don't build your house on the edge of a cliff (even if that has the best views).Buyers want flat land out the back. Set your house back a little.
