About this calculator

What it is
A land calculator that adds the cost of making a parcel buildable to the price of the parcel itself.
Who it is for
Buyers considering raw or unimproved land for a build, a hold, or a subdivision.
The problem it solves
Land is priced per acre and paid for per obstacle. Access, utilities, septic, grading and permits routinely cost more than the dirt.

The formula

All-in cost = land price + access + utilities + septic/well + grading + permits + carrying cost

Compare the all-in figure to what finished lots sell for locally. If the total approaches or exceeds finished-lot value, the parcel is priced as though the work is already done.

How to use it

  1. 01

    Confirm the parcel is legal to build on

    Check zoning, minimum lot size, setbacks and any recorded restrictions or easements.

  2. 02

    Price access and utilities

    Driveway or road, power distance, water or well, sewer or septic, and telecom.

  3. 03

    Price site work

    Clearing, grading, drainage and any wetland or slope constraints.

  4. 04

    Add soft costs and carry

    Surveys, perc tests, engineering, permits, and taxes and interest during the process.

  5. 05

    Compare to finished-lot value

    If the all-in total meets or exceeds finished lots nearby, the price is wrong.

When to use it

  • Evaluating an unimproved parcel before making an offer.
  • Comparing a raw parcel against a finished lot.
  • Testing whether a subdivision is economically worthwhile.

Common mistakes

Assuming buildable means permitted

Zoning allows a use. A permit requires a passing perc test, legal access, and compliance with setbacks and environmental rules.

Underestimating utility distance

Bringing power or water even a few hundred feet can cost tens of thousands.

Skipping the perc test

Without municipal sewer, a failed perc test can make a parcel unbuildable outright.

Forgetting the carry

Land generally cannot be financed cheaply, and taxes accrue during every month of approvals.

Questions people ask

How do I know if land is buildable?

Confirm zoning permits the use, the parcel meets minimum size and setbacks, legal access exists, and either sewer is available or the soil passes a perc test for septic. Any one of those failing can stop a build.

How much does it cost to make land buildable?

It varies widely, but access, utilities, septic or well, grading and permits commonly total tens of thousands of dollars and can exceed the price of the land itself.

Is raw land a good investment?

It can be, but it produces no income while you hold it and carries taxes and interest. The return depends entirely on buying below what the parcel is worth once improved.

What Property Intelligence™ adds

Property Intelligence pulls the zoning designation, parcel record and recorded easements for the address, and names each unknown — perc status, utility distance, access — rather than assuming it away.
