Plenty of townhouse buyers from the past five years would now like to sell their townhouse and move up to a single family home. But it has been difficult to do so recently because of adjustments in townhouse values.

Thus, I have counseled many townhouse owners that if they really want to move up to a single family home, that they ought to seriously consider leasing their townhouse instead of selling it.
This doesn't work for everyone (especially if you need to free up some equity in your townhouse) but it can be a great long-term decision.

unwillingly keeping your townhouse might be your best (unintentional) financial move yet to see how the owner of such a townhouse could potentially experience $230,000 of gain over 30 years of owning the townhouse.
If you can't sell, you should seriously consider leasing your townhouse, and I'd be happy to help you analyze the opportunity to see what would make the most sense for your situation.
