Firslty, the 5x salary offered by Abbey earlier this week is only being offered to those earninga dual income of over �50,000 with a _perfect_ credit score (a small minority) and generally not first time buyers.
With regard the increase in property values, mister Jo Bloggs _should_ NOT actually want his house price to increase (unless he needs to raise capital) as if his price increases, so does the next house he wants to buy (and although they generally increase on the same percentage terms - in cold hard cash it is far more - ie if you have a property worth �100,000 and it goes up by 10%, it is now worth �110,000 - great! Not so great is the house that you want to buy next has gone up from �150,000 to �165,000 (again 10% increase), but in real terms it has gone from a �50,000 increase in spend to a �55,000 increase in spend!
