Lets assume that is the non-bubble price in 2002
Lets assume 4% average appreciation per year
$295,000 x .04 = 11,800
In 2003 the price would be
$295,000 + $11,800 = $306,800
$306,800 x .04 = $12,272
In 2004 the price would be
$306,800 + $12,272 = $319,072
$319,072 x .04 = $12,762
In 2005 the price would be
$319,072 + $12,762 = $331,834
$331,834 x .04 = $13,273
In 2006 the price would be
$331,834 + $13,273 = $345,107
$345,107 x .04 = $13,804
In 2007 the price would be
$345,107 + $13,804 = $358,911
$358,911 x .04 = $14,356
In 2008 the price would be
$358,911 + $14,356 = $373,267
A lot of people think that housing prices will drop to (or below) the 2002 level.
IF this house was really worth $295,000 in 2002 (note the big IF)
at 4% appreciation (yes, in the past houses went up in value)
this house would be worth about $373,000 today.
Personally I would not take the chance. Just a 4% drop each year is over $14,000 per year in lost equity, and some econmists are saying 15% drop over the next few years.
We know one thing that seems for sure. Prices are not going up anytime soon, so be patient, you are not going to miss the boat. It could take years for prices to go up again.
By the way county assessments don't mean much. that just determines your property taxes. most houses are or will be selling for less than the county assessment. In a few years they will re assess the property. Of course the county is not really going to like that number to go down, it means less tax dollars in their budget.
