Good luck.
I'm no lawyer, but I've seen this exact situation unfold before. Multiple siblings inherit real estate, one wants to keep it, the others want to cash out. My Mom was a real estate broker for decades, and I've encountered it too in my locksmith business, when I'm called out to rekey a home that was involved in an inherited property dispute between siblings, that was finally settled. Leads to bad blood, family disputes, and hard feelings too often.
EVERY time, one of 3 things happened. The one who wants to keep it buys out the others (most common), or they sell it and split the proceeds, or they split the land into *equal value parcels and each owner moves on with their respective plans.
Most common was a certified appraisal to set the value, the one who stays pays the others their share of appraised value. With three owners, the keeper would pay the other two 1/3 ea of appraised value etc. ETA... In this situation, because those who want out are the parties initiating things, usually... they take on the burden of all expenses. They pay for the appraisal, they pay all title fees, they pay any/all legal fees.
* Parts of it may be more valuble than others. For example, high ground is worth more than low, water frontage is more valuable, and then there's value considerations for any timber or other crops, and access / easements etc. So it's much more complicated when you start trying to seperate it equally.
