I think you are still talking about a supply side issue there.
If a drab suburb only has 10% population growth but massive increase in home prices that is because the town council has only increased the available lots by 10%. There are a lot more people in the DC metro area now so the increase of people who want to live in your suburb has probably doubled in that 30 years.
Of course if a town issues no new building permits as the surrounding areas grow of course demand per unit will go up.
