Similar here Flip. My DF was a lovely man, I saw him every day, but after looking after my Mum until she died, he wanted to be out and about, rather than bothering with his home surroundings and he didn’t want me to take control, as he said he couldn’t cope with all the upheaval.
It was clean, but stuck in a time warp with Artexed walls, swirly whirly carpets, a pink bathroom suite, plus the original kitchen and heating system. The house itself was structurally sound.
After he died, I had it valued and was told it was a ‘builders project’ and as such, would be worth well below market value. Having a bit of a chat, the EA said if I could afford it, I could get the work done and benefit financially from the result. So, that’s what I did - a full refurb, including the garden and the bungalow sold for a realistic price to the first viewer, a local chap who had been following the builders progress with interest.
