A mobile home bill of sale is the written record that transfers ownership of a manufactured home from seller to buyer, and to be accepted by a title office it needs the parties’ legal names, a full description of the home with its serial number and HUD label numbers, the price, the date, signatures, and in most states a notary seal. It works alongside the signed-over title, a lien check, and a tax clearance. Get any of those pieces wrong and the transfer stalls.
Before drafting anything, make sure a bill of sale is the right document for your situation.
Bill of Sale or Deed?
How your state classifies the home decides which document you use. A mobile home on leased land, or one still on its axles, is almost always personal property, and the transfer works like selling a vehicle: a bill of sale plus a signed-over title. A home that has been permanently attached to a foundation and merged with the land underneath is typically real property, and that transfer uses a recorded deed, not a bill of sale.
Using the wrong document can void the sale or get rejected at the title office. If you own the land and the home together and want to convert the home to real property, most states require you to formally retire or surrender the mobile home title through the motor vehicle agency and the county recorder before a deed will work. If you’re not sure how your home is currently classified, check the title document itself or call your county assessor.
Find the Home’s Identifying Numbers First
Every manufactured home built after June 15, 1976 carries two identifiers you’ll need to copy onto the bill of sale: a HUD certification label on the outside and a data plate on the inside. Homes built before that date predate federal construction standards and may lack these markers, which can complicate the sale and limit financing.
The HUD certification label is a red metal plate with silver lettering riveted to the exterior of each transportable section, usually near the tail end. It shows a three-letter prefix (the inspection agency) followed by a six-digit number. A double-wide has two labels, one per section. Record every number on the bill of sale.
The data plate is a paper or metal tag inside the home, typically in a kitchen cabinet, near the main electrical panel, or in a bedroom closet.1U.S. Department of Housing and Urban Development (HUD). Manufactured Housing HUD Labels (Tags) It lists the manufacturer’s serial number, make, model, year of manufacture, and wind and snow load zones. The serial number on the data plate is what most states use as the VIN for title purposes.
The VIN may also appear on metal tags riveted to the frame or exterior, often at the tongue and hitch end, near the main entry door, or on the end wall opposite the hitch. If the data plate is missing or illegible, those exterior tags are the backup. Copy the numbers exactly. One transposed digit will cause a title rejection.
What the Bill of Sale Must Contain
Many states publish an official bill-of-sale form through their motor vehicle agency or housing department, and using the official form is the safest route. If your state doesn’t require a specific form, or you’re drafting your own, the document needs all of the following:
- Full legal names and addresses of the buyer and seller, exactly as they appear on government-issued ID. If an LLC or trust owns the home, use the entity’s legal name and the signer’s name and title.
- A description of the home: year of manufacture, make, model name, dimensions (length and width in feet), number of sections, and the serial number or VIN. Match the current title and data plate.
- Every HUD certification label number, from every section.
- The physical location of the home: street address or lot number, including the park name if any.
- The purchase price, written in both numbers and words. This figure is also what sales tax is calculated on.
- The date both parties sign.
- Payment method and terms. If the buyer paid in full by cash, check, or wire, say so. If any balance remains, spell out the schedule, interest rate, and what happens on default.
- A clear statement that the seller transfers all right, title, and interest in the home to the buyer.
- Signatures of both parties, with printed names underneath where the state requires it.
Write the price carefully. If the figure on the bill of sale conflicts with the figure on the signed title, most title offices will use the title’s number and reject the discrepancy. Keep the two documents consistent.
Add an As-Is Clause
Private mobile home sales are almost always as-is, and saying so in writing protects the seller from claims about defects discovered after closing. Without this language, a buyer who later finds a leaking roof or faulty wiring could argue the seller implicitly warranted the home’s condition.
The clause doesn’t need to be long. A sentence stating that the home is sold “as-is and with all faults,” that the buyer has had the chance to inspect the home or hire an inspector, and that the seller makes no warranties about condition is enough. If the seller does want to guarantee something specific, like a working furnace, write that out as a separate warranty with a clear expiration date rather than leaving it implied.
Buyers should use the inspection opportunity. Walk through and check the plumbing, electrical panel, HVAC, roof, flooring, and the underside for frame rust or water damage. For homes built before 1976, pay extra attention, since those units predate federal construction standards and some jurisdictions impose extra requirements on placing pre-HUD-code homes.
Check the Title for Liens Before You Pay
A bill of sale is only useful if the seller actually has clear title. Mobile homes classified as personal property are often financed with chattel loans secured by UCC-1 financing statements filed with the state’s secretary of state. If the seller still owes money on the home, that lien follows the property regardless of what the bill of sale says.
Before any money changes hands, run a UCC lien search through the secretary of state in the state where the home is located. Most states offer online portals that let you search by debtor name or by the home’s serial number. You’re looking for an active UCC-1 listing the mobile home as collateral. If one exists, the seller needs to pay off the loan and have the lender file a termination statement before closing.2Legal Information Institute (LII) / Cornell Law School. UCC 9-513 – Termination Statement
Don’t rely on the seller’s word that the loan is paid off. Get documentation of the release, or confirm the termination statement has actually been filed, before completing the purchase. When the seller’s loan isn’t paid off yet, the sale proceeds can satisfy it at closing. A simple escrow arrangement handles this cleanly: the buyer deposits the price, the escrow agent pays the lender, the lender releases the lien, and the remainder goes to the seller.
Get a Tax Clearance
Most jurisdictions require a tax clearance certificate, or certificate of taxes paid, before processing a title transfer. The county assessor or treasurer issues it, and it confirms all property taxes or mobile home taxes on the unit are current through the sale date. Without it, the title office will reject the paperwork.
If back taxes are owed, someone has to pay them before the certificate is issued. Sellers typically handle this, but it’s negotiable. What isn’t negotiable is the consequence: an outstanding tax debt blocks the transfer. Request the clearance early so any surprises surface well before signing day.
Sign in Front of a Notary
Many states require the bill of sale to be notarized before the title office will accept it. Even where notarization isn’t strictly mandatory, it adds fraud protection that matters if ownership is ever disputed. A notary verifies each signer’s identity through government photo ID and applies an official seal.
Some jurisdictions also require one or two disinterested witnesses, meaning people with no financial stake in the transaction and no family relationship to either party. Check your state’s requirements before signing day so you aren’t scrambling to find a witness at the last minute. If the title office rejects an un-notarized document, you’ll have to get both parties back together to re-sign, which is far more trouble than doing it right the first time.
Selling a Home in a Mobile Home Park
If the home sits on a rented lot in a land-lease community, the bill of sale covers the home only, not the land. But the sale still has to clear the park’s rules, and this is where deals fall apart more often than people expect.
Most park leases require the owner to notify management in writing before listing the home. The park typically reserves the right to approve the buyer, meaning your prospective purchaser will need to submit a residency application, pass a background and credit check, and agree to the park’s lease terms. Parks cannot unreasonably withhold approval, but reasonable criteria can include income requirements and criminal history checks. If the buyer is rejected, the sale doesn’t happen.
Some leases also give the park a right of first refusal, letting the park match the buyer’s offer and purchase the home itself before you can sell to a third party. Read the lease carefully before listing. A seller who skips the notice and approval steps risks having the park block the title transfer or terminate the lot lease, which can leave the buyer with a home and nowhere to put it.
The bill of sale itself doesn’t change for a park sale, but reference the lot lease, and the buyer should review the park’s rules directly with the park office rather than relying on the seller’s description.
Filing the Title Transfer
Once the bill of sale is signed and notarized and the tax clearance is in hand, the buyer files the paperwork with the appropriate state agency. In most states that’s the motor vehicle department; in some it’s the department of housing and community development. The package typically includes the original title signed over by the seller with the buyer’s name filled in, the notarized bill of sale, the tax clearance certificate, a title application form, and the title transfer fee (generally in the range of $35 to $85).
Buyers also pay sales or use tax at filing. Treatment varies: some states tax the full purchase price at the standard rate, others apply a reduced rate for manufactured homes, and a handful exempt used mobile homes entirely. Check with your state’s tax agency before filing. After payment, the agency processes the transfer and mails a new certificate of title. Turnaround runs several weeks. Keep the bill of sale, the old title, and all receipts together until the new title arrives, because those documents are the only proof of ownership during the processing window.
If the Original Title Is Missing
Older mobile homes, especially those that have changed hands informally, frequently come without a title. The simplest fix is for the seller to apply for a duplicate through the state’s motor vehicle agency before the sale. The seller files a sworn statement that the original was lost or destroyed, pays a modest fee, and waits for the replacement. This works if the seller is the owner of record and there are no outstanding liens.
If a duplicate isn’t possible because of an ownership gap, a break in the chain of title, or a home so old no title record exists, the buyer may need a bonded title. The buyer purchases a surety bond (typically a small percentage of the home’s value) that protects any undiscovered prior owner for a set period, usually three to five years. The state issues a title carrying a “bonded” notation, and once the bond period runs out, the notation is removed and the title becomes clean. Not every state offers bonded titles for mobile homes, and some require a court order instead, so check your state’s specific procedure.
In any of these situations, the bill of sale carries more weight than usual. It may be the strongest evidence the buyer has that they legitimately purchased the home. Include every identifying number you can find on the unit, and get it notarized.
