Hi,
The metric you need is income. Real estate shows the closest relationship to income levels over time; ideally incomes in that town/city. The data Rich has supplied shows SD household income rose by about 44% so …. 280K which is close to your numb.
The only other thing to watch out for is
1) was the real estate market high or low in late 99( see Rich’s graphs to judge)
and , if your analysis is made to reach a buy/sell decision,
2) this market may well under shoot fair LT value for months or even years due to the weight of foreclosures
