Just use common sense.When you get a request that asks if it is available when a quick look at the calendar or the inquiry show it is available then you should be on the look out.

If the latter, depending on the jurisdiction, YOU may need to be a licensed real estate agent/broker to engage in what’s commonly called “wholesaling” but is actually “flipping”.
