It depends upon what "almost nothing" means to you.
In most cases land is either purchased for cash or with the Seller's assistance in financing. Since land is relatively cheap, the Seller generally asks the Buyer pays 25% as a down-payment and their closing costs. Twenty five percent may "sound" like a lot, but the question is "of what amount?"
Can you have a lesser down-payment? Yes and no. It will depend upon the Seller's motivation and your tolerance for usury interest rates, for which AZ has no law.
If you need assistance with the purchase of a residential lot (regardless of density,) feel free to contact me. I can also provide contacts for agents in Prescott, White Mountains and Strawberry.
Best of luck!
