What this manufactured home calculator compares
A conventional calculator assumes there is one way to pay for a house. With a manufactured home there are two very different ones, and they lead to different rates, terms, fees and even legal ownership. The first treats the home and its land as real estate and uses a mortgage. The second treats the home alone as personal property and uses a chattel loan, usually while renting a lot. This page sets them next to each other so you can see what each path actually costs each month, how much cash it takes, and how much interest you pay.
How it works
For the mortgage path you enter the home price, the land price and the cost of putting the home on a permanent foundation and converting the title to real property. The loan covers all three, less your down payment, and the payment includes property tax and insurance. For the chattel path only the home price is financed, and lot rent replaces land and property tax. Change the rates and terms to match the quotes you have. The tool shows the all-in monthly cost for each and the difference.
How the numbers are calculated
Each loan uses the standard formula M = L × r × (1 + r)n ÷ ((1 + r)n − 1). Total interest is M × n − L. The mortgage path adds (home + land) × tax rate ÷ 12 and monthly insurance. The chattel path adds lot rent and insurance.
Worked example: $120,000 home, $60,000 land, 10% down
Mortgage path: a $171,000 loan at 7% over 30 years has principal and interest of $1,137.67. With $150 of tax and $100 of insurance the all-in cost is $1,388 a month, and you need about $19,000 down.
Chattel path: a $108,000 loan at 9.5% over 20 years costs $1,006.70. With $600 of lot rent and $100 of insurance, the total is $1,707 a month on $12,000 down. The chattel path costs about $319 more each month.
The mortgage path has more interest in dollars ($238,560 against $133,608) because the loan is larger and longer, but it also finances land you will own. The chattel path has no land equity at the end and lot rent that can rise.
What lenders check
The home itself
Look for the HUD certification label on each section, a manufacture date after June 15, 1976, and a foundation that meets HUD's permanent-foundation guidance. A missing label or a home that has been moved from its original site are common reasons a mortgage falls through.
Land and title
The home has to be retitled as real property with the land. If you are on leased land, a mortgage is generally not available and chattel financing is the route. Loan programs like the FHA loan calculator follow the same rules as any FHA loan once the home qualifies, and the VA and USDA can offer zero down.
Older homes and parks
For homes built before 1976, or homes in parks, see the mobile home calculator, which models ownership cost inside a park, lot rent growth and depreciation. Once you have a payment target, check that it fits with the affordability calculator.

Frequently asked questions
What is the difference between a manufactured home and a mobile home?
The date. A manufactured home was built after June 15, 1976, when the federal HUD code took effect, and carries a red HUD certification label on each section. A home built before that date is generally called a mobile home. The distinction matters because most government-backed loans require a post-1976 home.
What makes a manufactured home eligible for a regular mortgage?
Three things: it was built after June 15, 1976, it sits on a permanent foundation that meets HUD guidelines, and it is legally titled as real estate together with the land. When all three are true, FHA, VA, USDA and conventional programs treat it much like a site-built home.
What is a chattel loan?
A chattel loan is secured by the home itself as personal property, much like a car loan, instead of by real estate. It is used when the home sits in a park or on land you do not own. Rates are usually higher and terms shorter, often 15 to 20 years, so the monthly payment on the same price can be much higher.
How much does it cost to convert a home to real property?
Sources vary widely, from a few thousand dollars to tens of thousands, depending on foundation work, engineering certification, permits and title work. Get local quotes. The calculator has a field for it so you can test whether the conversion pays for itself.
Can I use an FHA loan for a manufactured home?
Yes. FHA Title II works like a standard FHA mortgage for a home on a permanent foundation with owned land, with 3.5% down at a 580 credit score. FHA Title I is designed for homes that are not on owned land, with shorter terms. The home must be your primary residence.
Why is my payment on a chattel loan so much higher?
A higher rate and a shorter term both push the payment up. A $108,000 loan at 9.5% over 20 years costs about $1,007 a month in principal and interest, while a mortgage at 7% over 30 years on the same amount would be closer to $719. Test your own rates and terms in the calculator.
