So I've been looking at a ranch type property for a weekend getaway/hunting opportunity and I was wondering what interest rates would be like? I assume they are not as low as home loans.

I assume 20% down would be necessary?
Any help is appreciated!

Land banks are cheap cheap right now. In the 3's

Farm credit lenders are generally the way to go. Every now and then I'll have a client with a bank they do lot with and they can get close. 3's is range with the various programs they have. 20% down is fairly standard but there are cases where I've had buyers get approved with as little as 10% down . . . I'd count on 20% as average.
