Converting a Mobile Home Title from Personal Property to Real Property
This guide gives you the file to assemble before you ask for a mortgage: the land record, title record, affidavit, foundation evidence and tax record. It also shows why Illinois and Mississippi reach the same goal with different paperwork. Start before you pay for foundation work, because the lender and your state decide what they will accept.
This is general information, not legal, tax or financing advice. Title, property-tax, permit and lender rules vary by state and locality.
What this changes--and what it does not
A home on land you own is not automatically real property. For a loan Fannie Mae can buy, the home must be legally classified as real property under the applicable state law, and the borrower generally must own the land. Fannie Mae also says the exact title route differs by state: some states cancel a personal-property certificate of title, while others use another way to show the real-property lien. See Fannie Mae's U.S. titling guidance, checked September 29, 2026, and Selling Guide B5-2-05, dated December 10, 2025.
That classification step does not approve a mortgage. A lender still decides whether the home, land, borrower and file meet its requirements.

Ask these questions before construction
"Permanently affixed" is not one national foundation recipe. Separate these three checks:
- State title law. It decides the conversion documents and the title action.
- Local approval. Ask the local building office which permits, inspections and records apply at this parcel.
- Lender evidence. Ask the prospective lender, in writing, what it wants before work begins. It may ask for foundation documents or a certification even if the title agency does not.
Keep the home identifiers too. Federal 24 CFR 3280.5, current eCFR text checked September 29, 2026, requires the data plate to show the serial number and HUD certification-label number or numbers. The label is separate from the data plate under 24 CFR 3280.11, current eCFR text checked September 29, 2026. The practical places to find and preserve them are in The HUD Tag guide.
Conversion checklist: document, signer and destination
Use this as a file checklist, not as a substitute for the current form in your state. The price column intentionally does not guess: the official materials used here do not provide one statewide total for county recording, permits, foundation work or lender review. Get each current charge from the county, state agency and provider before you order work.
| Step | Document or action | Who signs or certifies | Where it goes | Cost to confirm |
|---|---|---|---|---|
| 1 | Match the deed, title, home serial number and any lien release. | Owner supplies records; lienholder releases its lien if one exists. | Your records and the lender. | Title-search and lien-payoff amounts, if any. |
| 2 | Ask the local building office about the installation. | The office identifies local permit and inspection requirements. | Local building office. | Local permit and inspection charges. |
| 3 | Obtain the state affidavit and required foundation evidence. | The owner signs the affidavit; the state route determines any acknowledgment or certification. | County recorder/clerk or state title route. | Recording, notary and professional charges. |
| 4 | Record or submit the state conversion documents. | County recorder/clerk records; state agency processes the title action. | State-specific destination. | County and state filing charges. |
| 5 | Keep proof of the title action and ask about assessment. | County assessor handles the assessment record; owner supplies evidence. | Assessor and lender file. | Local assessment or tax amounts. |
| 6 | Give the completed file to the lender. | Owner provides it; lender decides eligibility. | Lender. | Lender's own fees, if any. |
Example only: Illinois and Mississippi paperwork sequence
Example only--paperwork sequence, not a real home or transaction. The only number in this comparison is the Illinois legal citation, 765 ILCS 170. Confirm the current forms and charges before filing.
| Step | Illinois | Mississippi | Who signs or certifies |
|---|---|---|---|
| 1 | Confirm that the land and home ownership fit the Illinois act before treating the home as real property. | Confirm the owner owns the home and land before using the permanent title-retirement route. | Owner; lender or title professional can verify records for a planned loan. |
| 2 | Have the home affixed to a permanent foundation and obtain the certification that Illinois requires with the affidavit. | Remove wheels and axles, then anchor and block the home under the Mississippi route. | In Illinois, a certified residential or general appraiser, licensed manufactured-home installer or licensed professional engineer may certify permanent affixation under the act. In Mississippi, follow the state route and applicable installation rules. |
| 3 | Complete, acknowledge and record the affidavit of affixation. | Complete DOR Form 78-908, the Affidavit of Affixation, and record it with the county Chancery Clerk. | In Illinois, every person with an ownership interest in the home signs; recording acknowledgment applies. Mississippi owner signs the affidavit; the current form controls acknowledgment. |
| 4 | File the certified recorded affidavit with the Illinois Secretary of State and complete the applicable vehicle-title requirements. | Take the certified recorded affidavit, land-ownership proof, existing title or other accepted ownership evidence, and DOR Form 78-906 to the county Tax Collector for forwarding to DOR. | Illinois Secretary of State title process; Mississippi county Tax Collector and DOR. |
| 5 | Give the recorded affidavit, title evidence, tax record and local/lender foundation documents to the lender. | DOR retires the certificate of title; give retired-title evidence, affidavit, tax record and local/lender foundation documents to the lender. | Owner provides; lender decides whether the collateral file qualifies. |
Illinois: affidavit plus title work
Illinois calls this law the Conveyance and Encumbrance of Manufactured Homes as Real Property and Severance Act, codified at 765 ILCS 170, current Illinois compilation checked September 29, 2026. The route is optional in general, but an owner who wants to convey or voluntarily encumber the home as real property needs the act's route. The home must be on a permanent foundation; the affidavit is recorded; a certified copy goes to the Secretary of State; and the applicable Illinois title requirements must be completed.
For this Illinois route, Section 5-5 says the home is affixed to a permanent foundation only when its wheels, axles and towing hitch are removed, it is anchored to real property by attachment to a permanent foundation, and it is connected to residential utilities. The official section was checked September 29, 2026; its source note gives Public Act 98-749, effective July 16, 2014. For a conveyance or voluntary encumbrance as real property, Section 5-10 requires every person with an ownership interest in the home to execute and record the affidavit. Its source note lists Public Act 98-749, effective July 16, 2014, as amended by Public Act 99-78, effective July 20, 2015.
The act lets four kinds of licensed or credentialed professionals certify permanent affixation: a certified residential appraiser, certified general appraiser, licensed manufactured-home installer or licensed professional engineer. That is a state title-law certification, not a promise that a lender will accept every foundation or every certifier. Compare the current statutory requirements with the Illinois affidavit form and ask the recorder what it charges and requires on the day you file.
Mississippi: affidavit plus retirement
Mississippi's Department of Revenue manufactured-home guidance, checked September 29, 2026, describes a different permanent route. The owner records Form 78-908, Affidavit of Affixation, with the county Chancery Clerk. The current Form 78-908 is revised May 2024. The owner then submits Form 78-906, Application for Retirement of a Manufactured or Mobile Home Certificate of Title, with the other required documents through the county Tax Collector. DOR retires the certificate of title.
Do not confuse that permanent route with Mississippi's tax-only option. DOR says that tax-only treatment leaves the certificate of title valid; permanent retirement does not. Ask the Tax Collector and DOR for the current forms and charges, rather than assuming that a county recording by itself retires the title.
Taxes and a later move
Conversion can change which record carries the home, but it does not supply a nationwide property-tax answer. In Mississippi's permanent route, DOR says the county Tax Assessor puts the home on the land rolls as real property after title retirement. Assessment value, rate, exemptions and any tax bill are local questions. Ask the county assessor how the completed filing will be assessed before you refinance or buy.
Moving a converted home later is also not a simple reversal. In Illinois, the same act includes a severance process; in Mississippi, the permanent-title-retirement route means the certificate is no longer valid. Do not move the home on the assumption that a new personal-property title will appear automatically. Ask the state title agency, county recorder and local building office about the required severance, new title, permits and reassessment before the move.
Final pre-refinance file check
Before asking a lender to review the file, make sure you have:
- the deed or other land-ownership evidence;
- the existing title and lien release, or the state's retirement/cancellation evidence;
- the recorded affidavit and certified copy where your state requires them;
- current tax-status information from the county;
- local permit and final-inspection evidence, if required locally;
- the data plate, serial number and HUD certification-label details; and
- the foundation documents and the lender's written list of required documents.
The sequence is deliberately cautious: ownership and title first, state conversion second, lender decision last. It is general information, not legal, tax or financing advice, and rules vary by state.
