One of my daughters and SIL are developing property they bought.. last year, they brought in power and got the well put in.. Foundation went in recently so they are on the way..
The well has 60+ gallons per minute using air test (that's the good news), but it is 720' deep. They are way over budget on well and will be stretched on putting pump in. I can't say they will be over budget on pump since they redid the budget once the well was drilled. They might haul water for a year, they highest priority is getting the house up before weather stops in the fall.
The local water district would connect them for $80k, which was not feasible, but they will end up over half that..
