Hi,
Try Homebuy direct, new gov scheme which will fund your deposit up to 30%. Some good options with these, however limitations are numerous, just a few:
* You can only have 2 beds if you are a childless couple (and don't work from home).
* The selection of homes is limited (but plenty of new builds).
* The loan for the deposit is interest free for 5 yrs, and I believe you can then pay monthly at the rate specified or it may be an option to add to your mortgage or you can sell up and you have to return 30% of current (i.e. not the price you paid) value to the lender.
* The deposit loan amount will be judged on your income basically the less you earn the more deposit % you may be able to lend. (You are not eligible if you earn over £60k jointly - so no big payrise until you've brought one!)

Nearly all home builders are partaking in the scheme. Google 'homebuy direct'
Good luck
