The difference of buying a home with a good well and one with hauled water is huge! Hauled water is not desirable, and it going to back people off from purchasing your property in the future. That said, there are a lot of bad wells in Rio Verde so if you end up buying one with a well, make sure it is a good one. A well can run from 20k to 50k in Rio Verde depending on where your property is located, and in some areas out there there is no water at all. I would dare to say that the differnce in terms of value can be up to 100k on a property, it is not just the cost of drilling a well (if even possible), but the risk of not finding any water at all.
That said, quite a few people in Rio Verde haul water and is ok with it, but the majority of buyers are not ok with it.
