Stage 1. Sit down with your partner and make a list of things you must have and things you would like. Discuss how you forsee the next 10 years or so (if you intend to live there that long). So for instance, my current essentials list are 2 bedrooms, kitchen, lounge, bathroom, garden. My want list are parking, an open plan kitchen diner, downstairs bathroom and spare bedroom (elderly mum) logburner, good-size sunny garden, not on a busy road, close to school, natural light, views.
Talk about what kind of houses you like (period/new), pet hates, and how you want to live (do you want a big kitchen where you can cook together, to hold endless parties, or have storage for 20 bicycles?)
Look at every home in your price range that meets your essential criteria and see how many of your wants it has or could have with some work. Look at the potential to extend/convert/ improve at some point.
Ignore the clutter, crap decor, revolting carpet etc, in fact actively seek out these properties as they may be better value than properties which have been 'presented' for sale. Or you may decide that you only want to look at homes that need absolutely nothing done in the next 5 years.
Be polite on viewings- turn up, ask questions, talk to the sellers, let them tell you all about their house. If you hate their taste don't say so. Be the people they would like to sell their precious home to.
Stage 2- When you find a possible purchase, then look at what is wrong with it that might need expensive work straight away. Check roof, wiring, heating, signs and smell of damp, any cracks, energy efficiency etc. Are you happy with the condition of bathroom/ kitchen or will you have to/ want to replace them? Everything has a life cycle- roofs and wiring 30-40 years, boilers, fitted kitchens 15 years or so, condition of windows etc. Make a list of questions you would want to ask a surveyor, and think about how much work you want to do/live through/pay for, and what you can live with.
And bearing that in mind, go with instinct and find somewhere you can both be happy. And then get a thorough survey so that you go into the purchase with your eyes open.
