Real estate is not the stock market and it's called buy & hold and not buy & sell for a reason.I did sell a few properties about 10 years ago when I learned the hard way that going into cheaper neighborhoods was not the right strategy for me, so that was basically a strategy correction and it was necessary, but also costly both in terms of dollars and time.

Byrna    it has an effective range of 60'  Have any experience with one of these?

This helps determine if I would be responsible for covering those costs.
