Buying New Construction in Alabama: Builder Incentives and Filing Class III Homestead by Dec 31 — Camellia Casebook

Updated October 2026

An Alabama builder's advertised payment can reflect a temporary rate buydown and a tax estimate based on an unfinished lot. Neither necessarily describes the payment you will owe after the introductory period ends and the completed house enters the assessment roll. Separate sales incentives from durable ownership costs before signing.

Price the incentive against the permanent loan

A temporary 2-1 buydown generally subsidizes payments at a rate two percentage points below the note rate in year one and one point below it in year two. The contractual note rate remains unchanged, and underwriting generally uses the full note-rate payment.

Ask for competing estimates showing a temporary buydown, permanent discount points and a price reduction where offered. A preferred-lender credit may be valuable, but compare its benefit against lender fees and the underlying rate.

Use today's rates as a starting point and the monthly payment calculator to model the unsubsidized payment. The Consumer Financial Protection Bureau explains the Loan Estimate fields needed for an apples-to-apples comparison.

File for the correct homestead treatment

Alabama's Class III owner-occupied single-family homestead assessment ratio is 10% of appraised fair market value. Class II non-owner-occupied property generally uses 20%. At the same value and millage, that assessment difference can double the tax before exemptions and other adjustments.

Contact the County Revenue Commissioner during the October 1 through December 31 filing period to establish the correct treatment. Eligibility depends on ownership, occupancy and the relevant assessment date; a December closing does not automatically establish eligibility for the current tax year.

Bring the recorded deed and requested occupancy documentation. Ask which tax year will reflect the change and whether additional homestead exemptions apply. The Alabama Department of Revenue explains the statewide framework, while the county processes the property-specific filing.

Replace lot-only estimates before closing

Request an estimated tax bill based on the completed home's expected assessed value. An escrow account funded from a vacant-lot bill can produce a shortage and a higher payment when the improvement is assessed.

Also verify final inspection requirements, certificate of occupancy, warranty coverage and responsibility for unfinished work. If using AHFA Step Up, include its 10-year second-mortgage payment when comparing builder offers. Finish with the closing cost estimator, separating true lender credits from expenses that are merely deferred.
