5 hectares in Yucatan stay for free

There is a very small concrete building sleeps one in a hammock or 2 if you put a bed. There is forest and a few Dragon fruit and piñuelas. There are guanacastle trees. There is a well. Rocky land.
All you have to do is improve the land while you stay there. And don't tamper with the mayan ruin area. You could set up tourism. If you put up a building.
Keep in mind that I will want the property back in about 5 to 10 years.
Santa rosa Maxcanú Yucatán terreno San Alexo. Get there and I'll see if Jose still has the keys if not you will have to cut the lock.

It's for sale if you have or get mexican citizenship. $15 000 usd

Is this:
Ejido Land, that the state of Mexico owns but allow you to use it
or regular land that I can have a bank setup a trust for (fideicomiso), or setup a LLC/corporation to buy the land for me?

It hijido. You need mexican citizenship to own it. Any tree cutting must be approved by the hijidal commissioner. It's possible to change the classification to private property but there is cost involved and then there would be property tax although it is vary low.

How much time and money would it cost for you to change it from Ejido Land to regular land (non-government owned).
So that I (or any foreigner) can buy it thru a LLC corporation or fideicomiso (trust setup by a bank).
