Need help with deal analysis

[Sam Rogers]

Hey guys. I'm looking for some feedback on how to approach a deal here. I'm looking at a fixer-upper sitting on 21 acres in a hot area just outside of my city. The homeowner wants 300K. The house is 1500sqft, the county says the land is worth 258K with the whole plot being 360K. The kicker is a cell tower with a 50yr lease bringing in $794/mo with 10% increases every 5yrs out back, but unseen from the house. There's just a lot of things going on here and I'm having trouble with how to put all these pieces together to figure out the actual value here.
