I think Rich used 2005 income increases of 4.6% on one of the bubble primer charts, but it was probably lower this year.
The $200,000 amount is only what somebody paid for the house in 99′, not what it was worth, so doing a calculation for fun is fine, but I wouldn’t base any decision on it. It’s almost ten years later and your target house and neighborhood are ten years older and the economy is in disarray unlike in 99′. Try finding out what rent for an equivalent house would be and use the Price to rent ratio from 99′ of about 11 or 12.
