To Rent or Sell

So we are in the "MAYBE" stages of going full time, like i said, Maybe. We plan on it but still want a home base. This would allow us to come home in a few years if and or as needed. So before we sell it all, move on and then maybe decide we only want to travel a few years then come home. The option of renting our place to maintain the payment and have brick and mortar to come home to, or sell it all and then have to buy again if and when we decide. Options, Options, and more options. So we tap other experience for your opinion, experience etc.. Thanks in advance.
