unless you are a speculator or is going to sell without having
to buy almost immediately else it wouldn't make much of a
differences even if the price when up or down alot.. you sell high
you'll have to buy high but if you sell high and buy low, there
must be reason why the property is sold below the current market
value..
also if you just buying and selling then the best time to buy is
not when price is high cause you'll probably have to pay for a
higher amount of interests unless no loan is required..
