I just pulled some numbers that may be of interest to you. These figures are all for only Brentwood, and only for homes with 5 or more bedrooms (is 5 enough for your family?)
There are currently 70 for sale, from $297,500 to $994,500
three are under $300,000
29 are under $400,000
53 are under $500,000
59 are under $600,000
A little history may also be worthwhile
Since 7/1/08, there have been 81 sold, from $302,000 to $1,010,00 - the average was $436,127.
In the month of July, there were 28 sales, at a median $427,475
In the month of August, it was 19 sales, at a median $400,000
In the month of September, 22 sales, median $398,000
In the month of October 13 sales (though given the month ended yesterday all October sales may not yet be showing in the MLS) at a median $420,000.
Here's a suggestion that might better answer your neighborhood question.
There are two ways that might work for you, if you want to invest a few hours some day.
1) we could go preview 2-3 houses in each price range ($300-$300,00, $300-$400,000 etc.)
2) we could go preview 2-3 houses in each neighborhood you find potentially attractive.
I'm certainly willing to invest that time if it would be helpful to you. In today's market, it just makes no sense to me to rent. . Click on my picture for my contact information.... more
