One of the first things you'll need to decide is when you are thinking of moving. If you are looking to move in the immediate future, your focus will be on making aesthetic improvements to make your home more 'sellable'. Alternatively, if a move is a year or more away you could benefit from taking on a more significant project to add value to your home.
I know it has been a long time coming but after one of the coldest and longest winters on record it looks like spring is finally here; rejoice! However, your excitement may be short-lived when you remember that spring is not just synonymous with new born animals and budding daffodils but the dreaded spring cleaning also.
