$69,000 Over 42 acres of southern Colorado land where you can make your vision come to life! An old office building is on site and is ready for a clean-out and renovation to make it your own. Lots of level, buildable space and easy access make this an ideal place for your new home or live/work situation. There is an old well that is capped off, so a new well and a septic system would be needed. There is fiber optic running down the highway but no electric so a solar/generator system would be needed.
A realistic estimate for installing a well, septic system, and solar setup ranges from $35,000 to $70,000+ total for a standard single-family, off-grid residence.
Estimated Capital Improvement Costs
| Utility | Average Cost Range | Key Factors & Local Specifics |
|---|---|---|
| Water Well | $12,000 – $25,000 | Drilling depth in San Luis often ranges from 150 to 350+ feet. Includes drilling (~$30–$65/ft), casing, submersible pump, pressure tank, and state permit fees. |
| Septic System | $10,000 – $20,000+ | Costilla County enforces state OWTS standards. Soil testing (perc test) and engineering designs dictate price. Rocky or poor-draining soil requires an engineered or mound system, pushing costs closer to $20,000–$30,000. |
| Off-Grid Solar System | $12,000 – $28,000 | San Luis gets excellent sun, but off-grid requires a battery bank (lithium-ion/LiFePO4) and inverter setup. Smaller setups (3–5 kW) for modest living run $12k–$16k; standard whole-house setups (8–10 kW) reach $25k+. |
| TOTAL | $34,000 – $73,000+ | Assumes full professional installation across all three utilities. |
Critical Local Considerations
1. Water Permitting (Colorado Division of Water Resources)
In Costilla County, domestic well permits generally require a minimum parcel size (often 35+ acres for full domestic and livestock use, or specific residential zoning permits for smaller lots). Always verify permit eligibility with the State Engineer’s Office before drilling.
- Septic Testing First: Schedule a perc test and soil profile pit before finalizing septic budgets. The high valley soil can vary wildly between soft alluvial silt and dense, hard clay/rock.
- Solar Tax Credits: Federal Investment Tax Credits (ITC) can reduce the net cost of the solar and battery storage components by up to 30%.
- Site Access & Trenching: Ensure the property line at Wildhorse Drive has clear, flat access for heavy equipment (drilling rigs and excavators). Rough terrain or long trenching lines to the home site will add to labor costs.
