Very often it is the home's kitchen and bathrooms that make a house look dated. While you may feel the only option would be to rip them out and install new, what about giving them a refresh instead? Refinishing kitchen cabinets and hardware will make it look like new, without the hefty price tag. You can also re-glaze bathtubs and sinks, giving them a new lease of life.
Do you have rooms in your house that you hardly ever use? Why not make them into a more useful space? For example, you could turn an unused guest bedroom into a home office, which is something many homebuyers are looking for these days.
Light, airy rooms are much more appealing than dark, cramped ones so look for ways to brighten up the home. Clear the outside of any trees and foliage that may be blocking light from windows and remove any heavy window treatments that make a room look much darker than it is. A fresh coat of paint throughout the home will also work wonders at brightening it up. Too much clutter can also make a room look small and cramped so try to minimize the number of knickknacks you have. It might even be best to place some of your belongings in storage.
Finally, It is important to remember that the majority of people will be looking at houses online before deciding which ones to go and see in person, this means that the photos you take of it should look as professional as possible. Rearrange rooms to highlight their best features and research various staging techniques that will help make your home look it's very best.
