Move or improve?
Your house might be in the ideal location but perhaps you think it doesn't quite meet your changing needs. Before starting to look for a new home, what about updating the one that you're currently in?
Have a think about the reasons for your improvement. For example, is it more important to increase your property's value or to make your home more comfortable? Usually it's a bit of both. Bear in mind that if you move soon after making a costly improvement, you may not recover your costs.
Improvements can make a home more saleable rather than more valuable. For example, spending £15,000 on a new kitchen will not raise the value of your property by £15,000 but it will be more likely to attract buyers when you decide to sell.
