1. Ensure that you are realistic when working out exactly how much you can afford to spend on your new house. You should ensure the intended mortgage is affordable (by doing a budget calculation) and it is wise to seek a Decision in Principle certificate, so that you know how much you can offer once you have found a suitable property. Even a newly built house will require some sort of furnishings, whereas older properties may require extensive work, such as re-flooring, tiling or renewing the wiring. Make sure that you factor in all these likely expenses, in addition to the purchase price, and other fees such as conveyancing and stamp duty.
