I'm having a well drilled at our offgrid property in Montana. Quoted at $60/foot and expect water at about 150 feet. Add in a pump, pipe, wire, pressure tank etc and I expect to pay about $15k. But keep in mind, the only cost you'll have going fwd is electricity. Pump/ pressure tank should last 10+ yrs. Your mileage may vary.
Property taxes are super cheap now because we dont have any services yet ($75/yr on 20 acres) I'll answer more questions if you gottem.
Septic vs sewer: septic is self- reliant and completely on your property. Might have a small pump or not depending on your lot. Call in a truck every 5 yrs or so at maybe $300 to pump your tank out. Sewer is a monthly fee to city, forever and ever. Maybe $40/mo?
