95% mortgages are back on the market, and although you pay more for them, after a few years you'd have paid off enough equity to switch to a 90% style rate.
But yeah, don't forget to factor in all the fees that come with buying - stamp duty (1% of house cost when house is over 125k) and solicitor stuff. I think when we last sold we ended up paying out about 5k, but that also included estate agent fees and selling solicitor fees too.
