OPEN RESEARCH / SEPTEMBER 6, 2026
Three decisions behind the build.
A first edition of inspectable research: the price, the missing scope and the date that changes the cash plan.
A posted material price, a complete installed package and a funded building schedule answer different questions. This edition connects them without hiding the gaps.
01 / MATCH THE SCOPE
The panel price is only the beginning.
+$1,240In the reference geometry, 56 ZIP panels cost this much more than 56 plain OSB panels at the reviewed web-listing prices. That difference covers panel material only.
The tape, weather barriers, flashing, fasteners and installation still need a matched comparison. The lower panel subtotal cannot establish the lower completed assembly cost.

A mapped pipe is not a service commitment.
Written scopeRaleigh directs applicants to establish service availability with its water-review team using the address, utility needs and service size. Its process also distinguishes developer-installed connections and other requirements.
Before fixing the land offer, record the connection point, work responsibility and additional allowance. The decision desk shows how the entered range changes cash and profit.

03 / KEEP THE CLOCKS SEPARATE
Review, construction and closing have different clocks.
6.1 monthsThe published 2025 U.S. built-for-sale cohort averaged this duration from construction start to completion. It does not include the land acquisition or permit process.
Raleigh lists a 10-business-day first-review target and 5-business-day additional-review target for new single-family, duplex and townhouse applications. These are goals, not total permit durations or guarantees. The closing date needs its own assumption.

Read the public scorecardEdition, coverage and source notes
This edition was reviewed September 6, 2026. Its 10 material observations are a small public-listing sample. Home Depot store and delivery geography are unverified; the roofing price is from a Bristol, Pennsylvania supplier. No local installed quote or transaction dataset is implied. The reference kit prices 3 of 5 selected raw-material lines; it is not a finished-home estimate.
The reference shape is 30 × 60 ft with 9 ft walls. Quantities and waste assumptions are shown in the cost book. This is the first edition, so no historical price move is inferred. A future edition requires another source review; this page does not refresh its prices automatically or send a newsletter.
