We want to downsize, and have joined a few sites to try and find a mutual exchange (Housing Association) Yes, I know we are fortunate to have a social housing property, but I have been a HA tenant for many years and have been working and paying rent for at least 95% of that time, excluding a period where I was unable to work due to health problems.
We are being quite specific about where we want to go and are making this clear, but I have had so many people get in touch asking if I want their property in a completely different area and then getting shirty when I say No Thank You. I've had people messaging me telling me how there are 8/9/10 of them in their house and their Daughter/Daughter in law/Niece is about to have a baby and they really "need" my house.
I'm sorry, it sucks to be in that situation but it's not my fault and I'm not somehow morally obliged to agree to move away from where we need to be (Work, elderly Dad, Son's work) to solve your problems.
Oh, and if your pictures of your home that you think suitable to post online include dirty toilets with the lid up, piles of crap in your lounge and filthy looking kitchens, then why be surprised that people are not too keen? Moving is a pain as it is without thinking that we are going to have to scrub the place from top to bottom!
