Who cares about inflation adjusted price when you have a mortgage ? Your rate will be X for Y years, as long as your income keeps up with inflation you'll get a net discount. Buying a property with loans is a good way of betting on inflation - I don't know if it will happen but if it does you'll win.
Worst case scenario is recession, you have reduced income and housing prices plummet - I don't see this playing out, running low interest rates to high inflation seems likely to me.
