Memorial and Tanglewood are similar neighborhoods, but right now Tanglewood has a record number of homes on the market and Memorial has low inventory. This is because out-of-towners (not having the private school option) move to Memorial rather than Tanglewood.
Something to think about-Tanglewood has some great values right now. You can pay a lot of private school tuition with what you'd save by living in Tanglewood and there are plenty of good private schools!
Buyers need to take a hard look at this. As soon as a few of these homes sell, the market will start moving.
