1. The Exterior
A potential buyer can be put off immediately if the exterior of the property is unattractive. Make sure your garden is well kept, the windows are clean and there is no litter about. It all helps to create a good impression.
2. The Neighbourhood
Unfortunately, there is not much you can do about the area the property is situated in, but you should bare it in mind when selling.
Have a look over the fence and convince your neighbours to smarten up with the offer of a helping hand. It can really help with the impression of the whole street.
In general, buyers want properties to be in the best possible condition when they buy them, and will be put off by evidence of neglect. If you have peeling wallpaper, chipped paint or any evidence of damp, sort it out before you put your house up for sale.
Your pets may be an asset in your eyes, but potential buyers may see differently. Dogs especially create a smell that can be off-putting, and a lot of pets cause damage to homes, so be sure to fix anything that may have been broken!
