Neighbor Passed Away,Can I trade My Vacation Home For Their Home?

[Danny N.]

Ok so sadly, our neighbor passed away at the age of 90. We live in the center of town and double lots are very rare, her home is worth about $600,000 lot value and the structure is a home from the 40s worth nothing. Anyways I own a vacation condo in another state worth around $650,000. What happened is our neighbor had no kids so she left the home to a relative who doesn't live anywhere near this home, actually she lives very far away. We were talking bc she would like to sell the home and I would love to buy it. I would like to learn more about possibly trading the vacation home in south florida for the home next door. Her house is paid off, my home in south florida has a mortgage of 228,550 left but I can pay it off if it will make it simpler but she was open to the idea of a beach house and i would love the home next door. What would be the next step in working something like this out? A realtor in texas or a realtor in florida or an attorney?

What would the taxes/fees/etc involved in something like this be called and does it have a name for me to read up on more
