I'm assuming this gets asked but I am a dum dum with the search functions. Never owned land before but I'm looking at purchasing 5 acres that currently as an Ag exemption and building a home in the property. What do I need to consider in terms of whether / how I can keep that exemption? The Comptrollers site talks about 5 years of use but I'm not sure if how the previous landowner used the property was relevant. I'm also not sure how the building of a dwelling comes into play (ie does that portion of land have to be carved out of the exemption?). I've also read size can be relevant (something like 5 acres for certain livestock but 10 or 15 minimum for other livestock).
