One of the main questions I get on valuations is "should I do works on the property before selling?".Generally speaking, the answer is no. Minor repairs and a lick of paint are simple cost-effective ways that go a long way to create a more desirable space. However on the whole, drastic changes like a new kitchen, bathroom or even a loft conversion are not usually the way forward. Yes you will add value, especially adding square footage in the form of an extension or loft conversion and, with the latter, you could achieve a greater return than you outlay. However, is it really worth the time and effort if you are just going to sell straight away?If you are doing it for your own needs and will enjoy the fruits of your labour then go for it. Truth be told, if you are thinking of doing works just to sell I wouldn't go out of your way to put your own touch on it, different buyers have different taste and you can't guarantee your refurbishment will appeal to buyers. I've been on countless valuations where the owners are living in tired homes and they think a B&Q kitchen (other kitchen outlets also available!) will get them an extra £50k. I just think to myself, why did you live like this for so many years when you could have enjoyed a new kitchen and bathroom yourself!Just by changing such rooms is not enough to appeal to new buyers and, in some cases, can put prospective buyers off further as they would rather have a say in the finish, spec, colour, etc.Traditionally in the areas I cover, namely Shoreditch, Hackney and Bow, the creative buyers could see past even the most odorous of pig sties and have a vision of the space they wanted to create. In fact, I have been involved in a number of sales whereby a run-down probate house has sold for between £30k and £50k less than a nice house on the street. This is despite it needing over £100k works to make it liveable. It seems the worse the condition, the more desirable it became.Times have changed of late and I am experiencing a noticeable swing in the pendulum. The demand for really poor properties such as probates is still present. However, now it has to be the right price and those that are immaculate are getting a noticeable increase in viewing activity, multiple offers and even premium prices achieved. Also, those in the middle i.e. the tired properties needing more minor cosmetic work such as ex buy-to-lets are really struggling more than ever.
