Having gone through some things similar to this.My parents are getting older. In theory, my brother may assume ownership of their property at some point. With the recent crazy price increases, buying out my half is well beyond anything he could ever afford, yet alone paying them so they have money for alternate living arrangements. To make the finances work, we may have to subdivide and I own most of the land while he gets the house and a few acres. It was included in the ORM as my parents are not developers so the land got locked up. Last I checked, you are allowed one split into two lots. It is not a simple situation. If my parents sell it and spend it all, good for them. It would be annoying if he got gifted everything to try to correct for his poor choices. Once land leaves the family, you will never get it back. I don't use it often but I don't want it to disappear forever.
Park the emotion, calculate the money. TVM, what if it was sold and the money invested (or used to pay debt), what is the FV needed to be to break even, how much does it need to increase in value each year to cover this and all the carrying costs. Once all that is nailed down you can figure out the cost of the personal attachment then decide what is best. Most people will refuse to do this for one of two reasons IME, 1) they are afraid of the outcome or 2) they don't know how to do it/don't understand (in your case GG from your posts the second one is not you....).
Land is just another inanimate object...
