Every line the build has a number for is below. Most of the post-gate costs are still honest question marks, and they fill in as the work reaches them. Nothing here is projected before it is earned.
| Item | Status | Amount |
|---|---|---|
| Soil and perc evaluation | Committed | $1,600 |
| Septic construction permit | Planned | $400 |
| Septic inspection | Planned | $100 |
| Well notice of intent | Planned | $75 |
| Well drilling and pump | Planned | TBD |
| Building permit | Planned | TBD |
| E-911 address | Planned | low or none |
| Storm-shelter engineering | Planned | TBD |
| Foundation stamp | Planned | TBD |
| Gravel driveway and access | Planned | TBD |
| Septic system install | The fork | TBD |
| Land | Owned | withheld |
The big swing is still ahead. The perc result decides whether the septic is a simple gravity system or an engineered one, and that single line can move the budget by thousands. Until the dirt decides, both stay live: about $2,100 conventional, about $2,300 engineered, on the fees known so far. The install itself is the dominant cost, quoted only after the result.
The two numbers we're chasing
Filled in honestly as they're earned, never projected:
| Mortgage avoided | Pending | the financed cost of a comparable home, minus this one |
| Cost saved, self-performed and AI-orchestrated vs hiring out | Pending | per phase, as they close |
This page mirrors the build's cost ledger, the system of record. Figures are cleared for public view. The location never gets more specific than Cumberland County, Tennessee, and the land price stays off until it can't be used to find the place. Watching the build?
