Turning current primary into rental

[Savannah NA]

We bought our first property one year ago and it is our primary house. We recently spoke with our lender about getting started with investment properties and she suggested one of our options would be to purchase a new primary home and turn our current one into either a STR or LTR.

We live in the Navarre Florida area, so to Airbnb seems very profitable especially after looking at others in our neighborhood. Our current home was $260k with 3% interest rate. Even a long term rental seems well worth it. 

Does anyone have advice or suggestions? We are new to this and want to try and get it right.
