[quote=walterwhite] All sort of absurd as the house will be worth a third less in 2012[/quote]
In that context the 2% is irrelevant.
I personally think you are getting hung up unnecessarily. It is impossible to assess the value of a house to within 2%. This is noise. So, the point comes down to, do you like the house ? Does it suit your needs ? (We already know you can afford it).
Are you paying a premium above rent. If not, or if that premium is small enough who cares if it worth half what you paid for it in 30 years. You would essentially own it for the price of rent.
