Buying raw land that is zoned Agricultural. What loan options?

[Vincent Russo]

My wife and I found 48 archers zoned agricultural in Harford County Maryland. She runs a horse training business but we do not own any of our land. We want to buy this land and use if for this purpose. There are no structures on the property.  What loan options are out there to get us in this property at the lowest amount out of pocket? What tax incentives are there? We own a rental and a primary home. This is our first go at purchasing raw land. 

Thanks!
