I feel your pain! Am on £35k, no debts (apart from student loan) and have £25k in savings, which would easily cover the deposit/fees/furniture etc for most shared ownerships - but my salary doesn't qualify for any!
There seem to be a few minimum salary price points. Since looking for last three months (admittedly South London and surrounds so extortionate) have seen only one for 33k and 35k minimum salary (both were already under offer), a couple for 37.5k, a few for 42.5k, but the vast majority seem to be 47k, 52k, or more. It's so depressing isn't it.
In the housing associations' defence, they work it out so that you don't pay more than 40% of your take home salary towards the mortgage/rent/service charge, which makes sense.
However was chatting to some friends about this and they said that you can ignore the minimum salary and get accepted anyway (but I guess that would mean paying more than 40% which probably isn't advisable). And was talking to a mortgage adviser the other week who reassured that, yes, people DO get houses on our wage, it just may take time to find the right one.
The other tip I've had is to go for second hand properties rather than new builds which aren't as overpriced and have less service charge.
Also, with regard to getting a lodger to help pay, I know someone who's done that and it's working out well. However, they don't take that into account when applying, so you're still in a pickle if you can't qualify in the first place (or only manage to get a one-bed). Fyi the friend who did that found it easy to qualify for a two bed place as they're earning more around the 50k mark. They had it all done and dusted and moved in within two months of deciding to go down the shared-ownership route...grrrrr!
So for me, plan is to get a job for 40k plus then hope for the best. But that's easier said than done of course as that's quite a big leap.
With regard to the poster from Southend - hello, I grew up in that area! Have seriously thought about moving back, but there are two issues 1. paying up to £250pm to commute on the C2C and 2. As a single person it's sad to leave your friends/life to go back, and it gives you a smaller pool of people to potentially find a future partner to share costs with! Although I totally get that you need to be willing to sacrifice to get on the property ladder.
