I was FTM during the 2008 crash. DH and I had saved and saved and managed to pull together a 10% deposit on a teeny postage stamp sized flat (that we loved, incidentally). Lending criteria kept tightening even whilst our application was in flight. At the last moment, our lender suddenly declared their criteria had changed again and they'd only accept 15%+ deposit. Clearly we didn't have another 15% lying around (we were going to have to put solicitors fees on our credit card as it was!) so we had to pull out. The irony is we ended up having to continue renting which was more per month than the mortgage payments we were applying for.
So, crashing prices doesn't always make it easier for FTBs. The economy is more balanced than that, and generally when it swings for one section it'll still have an impact for the opposite side.
