It's a tough one. I'm in the process of buying a share in a flat because it's the only way I can get on the ladder. I'm getting a mortgage for 75% of the flat and will then pay rent on the other portion. The amount of rent is set by each housing association and varies wildly - some properties just aren't worth considering cause the rent is as much as that percentage of mortgage. Check your figures before making a decision. I'm buying new build directly from the HA and have had to prove that I don't earn enough to buy the flat outright but I have enough to pay the mortgage, rent and service charge (catch 22!) Luckily, I've been accepted but it took several months for my application to go through. I also had to prove that I have to live in the area (my job is there and I'm doing a 80 mile round trip commute every day). With part ownership you only make any profit on your percentage, but, on the other hand, this is less of a risk if the housing market is unsteady. Also, with many schemes you can buy out further shares in the property in years to come (known as 'staircasing'). Mine becomes eligible after a year and hopefully by then I might be in a better position to pay the full mortgage and buy the flat outright. I'm also happier about the fact that all my neighbours will be (at least for the first year) owner-occupiers and not tenants. Finally (and I thought I was going to keep this brief!) only a handful of mortgage lenders will do shared ownership mortgages (such as Nationwide) and they take much longer to process. But, hopefully, it will be worth it in the end - I think more people will be doing this in future as the gap between wages and properties widens. Good luck!
