Mobile Home Installment Sale Contract Template for the United States

A mobile home sales contract, also called a manufactured home purchase agreement, is a legally binding agreement that lets you buy a mobile home through structured payments over time rather than paying the full amount upfront. The contract sets the terms of the sale while protecting both your interests as a buyer and the seller's financial security throughout the payment period. When financing is involved, it doubles as an installment sales contract, recording the purchase price, the payment schedule, and the security interest that backs the loan.

What is a mobile home sales contract?

It's a written purchase agreement between a buyer and seller for a manufactured home. A cash sale can be short, but most mobile home purchases involve installment payments, so the contract also functions as a financing document. It identifies the home (make, model, year, dimensions, HUD label or serial number), the total purchase price, any down payment, the interest rate, the number and amount of payments, and what happens if a payment is missed.

When do you need this document?

You need this contract when buying a mobile home through a financing arrangement where you'll make regular payments over months or years. This is common when buying from dealers, private sellers, or manufacturers who offer in-house financing. The contract is essential when the seller retains a security interest in the mobile home until you complete all payments, so it serves as both a sales agreement and a financing document. You'll also want it when traditional bank financing isn't available or when seller financing offers more favorable terms than a conventional loan.

What should a mobile home sales contract include?

A complete agreement for a mobile home installment sale covers the following:

• Names and contact details of the buyer and seller.
• A full description of the mobile home, including make, model, year, size, and the HUD certification label or vehicle identification number.
• The purchase price, down payment, and financed balance.
• The payment schedule, interest rate, and annual percentage rate (APR).
• The security interest and the seller's rights if you default.
• Insurance, property tax, and maintenance responsibilities.
• Any restrictions on moving or modifying the home during the payment period.
• Title transfer and lien-recording details.
• Signature blocks where both parties sign the document.

Key legal considerations

The contract must clearly establish the seller's security interest in the mobile home, giving them the legal right to repossess it if you default. Payment terms should specify the exact amount, due dates, interest rates, and any penalties for late payments. Insurance requirements are important; you'll typically need to maintain comprehensive coverage naming the seller as a loss payee until final payment. Default provisions should outline what counts as a breach and the seller's remedies, including repossession procedures and your rights during default. The contract should also address property taxes, maintenance responsibilities, and any restrictions on relocating or modifying the mobile home while payments are outstanding.

How do you complete and sign the contract?

Start by filling in the details above, review the payment terms and disclosures, then have both the buyer and seller sign the document. Many states require the security interest to be recorded with a state agency and the title updated to show the lien, so follow your state's titling and lien-recording steps after signing. Some purchases also depend on lender approval or park management approval before completion. Keep a signed copy for your records. GenieAI can draft this legal document, flag risks against your terms, and produce a ready-to-sign version so commercial teams handle contracts like this without waiting on outside counsel. If you're renting the land beneath the home, pair this contract with a mobile home lot lease agreement covering the pitch.

Is an installment sales contract the same as a mortgage?

Not exactly. With a mortgage, a lender advances the funds and takes a lien on the property. With an installment sales contract, the seller finances the purchase directly and keeps a security interest in the mobile home until you finish paying. This is a popular route for manufactured homes because dealer and private-seller financing is widely available. Federal disclosure rules still apply, so the buyer receives the same credit-cost information they would under a conventional loan.

Legal requirements in the United States

Federal law regulates mobile home installment sales through several statutes. The Truth in Lending Act (TILA) requires sellers to provide standardized disclosures about credit terms, including the annual percentage rate (APR) and total finance charges, so you understand the true cost of financing. The Real Estate Settlement Procedures Act (RESPA) governs disclosures about loan servicing and escrow practices when applicable. The Equal Credit Opportunity Act (ECOA) prohibits discrimination in financing based on race, color, religion, national origin, sex, marital status, age, or public assistance status. The Fair Housing Act extends these protections to housing-related transactions, including mobile home sales. State laws may add requirements for manufactured housing, such as specific disclosure forms, cooling-off periods, and warranty provisions. Some states require registration of security interests with a state agency, while others mandate specific contract language or buyer-protection clauses. Requirements vary by state, so check the rules that apply where the home is located.

What are the benefits of a written contract?

A written purchase agreement gives both sides a clear record of what was agreed, which reduces disputes over payment terms, the condition of the home, and each party's rights reserved on default. For the buyer, it confirms the exact cost of financing and the path to full ownership once payments are complete. For the seller, it secures the security interest and the remedies available if the buyer stops paying. As a signed legal form recognized under state and federal law, it turns a handshake into an enforceable set of obligations.
