While getting an extension on your house may initially cost money, it will massively add to the value of your home and you'll more than make your money back. If you don't have room to extend, then you could gain extra space by considering converting your attic. Extra rooms - especially extra bedrooms - are a good long term investment and are a really good way of adding value as it appeals to many buyers when you're trying to sell your house.
The kitchen and bathroom are both really important in terms of selling your house and increasing its value. You should make sure that you have modern fittings that mean any future residents of the house don't need to worry about replacing them. Modern appliances increase the value of your home, so you can add worth and improve your energy usage through installing energy efficient fridges, freezers and other appliances. This will help you use less energy in the long run and appeal to any potential buyers.
Improving your energy efficiency is one of the things evaluators look at when they price your home, so it's a good idea to get double glazed windows. These help keep the heat in and will add value to your house. You should also replace any wooden window frames with vinyl ones as this will boost the value further. Make your home even more appealing to potential buyers by upgrading your central heating system so it as efficient as it can possibly be, adding yet more value.
While a new roof can be an expensive thing to buy, it's definitely a good long term investment. Not only will a good new roof last you for years to come, but it will look attractive and massively boost the value of your house through efficiency. This means it can be a great idea to replace old, crumbling roofs as new ones are much better insulated and will retain more heat. Give your house a final boost through landscaping your garden to make it as attractive as possible.
