Moving House

I was diagnosed with rheumatoid arthritis last year while I was in hospital with pneumonia -Can anyone give advice on moving - live in a property that has damp and mouldy not as bad this year as landlord put in air vents but still want to move. It looks unlikely myself and my husband will be entitled to council/housing association home as we privately rent and have some savings. We have looked at the websites for council and it still looks very unlikely.
