I was told, 3 years ago, that often realtors buy up homes. Rent them for a year and then sell them. That was before the 2021 "gold rush" in T V. For a while there T V went to a lottery system to purchase so doubt there was an "insider" system going on. True or not people flip them after the one year mark. Each time new areas open up you see a lot of houses for sale. Can't go wrong with flipping in the bubble... after 1 yr.
