Hi Dunga - I don't know the full picture but just this week I sent an email on behalf of one of my sellers to her local housing officer in the UK. My client didn't give me all the details but said that if she could prove that her house here was worth less than £85,000 then she could claim benefits - I am assuming Housing Benefit?
You will find that the rules for different benefits set different levels of savings but if you go back with a decent amount of money from a house sale then you will not get any means tested benefits.
Houses here in the southern Costa Blanca are selling and we are very busy - BUT they need to be really low priced before we can even get viewings. Even then we are still getting offers of 20 - 25% below an asking price that was already 50% of what the owners bought them for!
If you are able to price your property correctly - assuming you don't have negative equity - then there are lots of buyers out there now.
If you are reluctant to go back and hope to return some day, have you considered trying to let your house instead?
Good luck whatever you decide to do.
