@joefromchicago,
Painting an odd color can reduce your home value, again this is all personal preference, but just think would you really want to live next a house that you see all the time that is bright orange or something? Some people will not care, just as if you were to buy a place and they had really odd colors on their walls, however, if you have neutral normal type colors it will appeal to more and therefore be easier to sell. Being some one recently in the market to sell and buy, I personally have experienced this.
Here are some others:
Here are some actions that can help you and your neighbors maintain your property values:
1. Pay your mortgage and homeowner association dues on time.
2. Keep your home painted and in good repair. Paint your home a color that compliments the architectural theme of the neighborhood or blends with the paint colors of the other homes in the neighborhood.
3. Keep your roof in good repair.
4. Do not leave junk lying around the outside your home. Purchase a shed or other storage container to organize your gardening pots, tools, tires, etc. If items are worn or broken, dispose of them through your trash pick-up or take them to the dump or a recycle center instead of leaving them discarded around the outside of your home.
5. Make sure your grass and shrubs are trimmed and neat. Keep weeds pulled and the grass mowed a healthy height for the type of grass. Overgrown landscapes are habitats for rodents, snakes, and other pests. Overgrown shrubs and trees also provide hiding spaces for criminals.
6. Do not leave your trash and recycling containers out after pick-up. Besides being a visual distraction, they can become road hazards. Try to arrange for someone to return the containers from the roadsides if you cannot. Be a good neighbor and bring another neighbor's containers in as an act of kindness, especially if your neighbor is in ill health or physically frail.
7. Manage the parking of your family cars in a neat and orderly manner on your own property. However, parking your cars on your lawn destroys your lawn and can contribute to a decrease in the value of the neighborhood. Try not park in the road in front of your neighbor’s home except for special circumstances. Some neighborhoods have ordinances against parking in the street.
8. Keep toys and recreational items stored neatly in the garage, carport, or backyard. Teach your children to put away their toys after use and not leave them lying about the yard. If you have a boat or recreational vehicle, park it in an approved designated area in the neighborhood.
good info just if you are interested -
