Bought a property via a housing association through right-to-buy. I need to save for either house extension or buying 2nd property in 5 years. Placing larger deposit and higher monthly mortgage payments gives more favourable interest rates. I want to know whether I'll be able to release equity in 5 years time?I asked HSBC mortgage consultant at my first meeting, who suggested asking the housing association, who passed on the question to their solicitor, and I never for a response - despite chasing up and a few months passing by.What are the rules around equity release? Who decides? Where can I find whether or not I can release equity?
