Ugh, we are 2 years down the track of buying a similar but 3 bed semi in the southwest. We have spent around £50k, rewiring, reflooring and general decor, new shower room to replace ancient bathroom, replacement cupboard doors in kitchen to save money but still had to put in new white goods and hob and sink and flooring. Another £10k went on the garden, seating area, pergola, bit of landscaping, hedging.
New windows throughout, got a good deal.
We kept the 25 year old boiler because the central heating engineer said it was a good one.
We are now exhausted and saying never again, materials and labour are much more expensive than in the past. I'd be very cautious, look at what houses in the area are going for. If you love it, OK, otherwise keep looking, that's my opinion.
