unfortunately for you those do not add value that you can recover in a sales price. bathrooms and kitchens are matters of personal taste, they either appeal to buyers until they can make their own mark, or they put them off, but they do not add value. Log burners may add character but also suggest the house is cold and the heating system inadequate.
I accept that solar panels can be valued on the basis of annual income v purchase price, so have a "value" before the purchase has been paid off, but they do not increase the profit on a property.
As ever, location and price are the real factors. There are only 3 properties for sale in your entire village. What is the appeal of that village compared to others?
I agree that your 2 bed end of terrace bungalow at 210k compares favourably with your direct competitor, the 3 bed end of terrace at the other end of your road (complete with disabled person adaptions) at offers over 195k, but the market is poor at the moment. I note the 4 bed semi detached house is now being sold at auction suggesting they have found it impossible to sell conventionally.
put yourself in the frame of mind you were in when you purchased. What appealed then?
Who is your target market???
Your street is characterised by bungalows and a few (ex council?) houses at its end. It looks to be an area for old people to live out their end in, not those starting families? Even then with no shops and only a village hall, there does not seem much to do there except travel out to somewhere else.
Location and price !!!!
