Mobile Home Depreciation Calculator

The depreciation curve

Manufactured homes lose value fastest in the first two years, then slow down — with noticeable step-downs around years 10 and 20. We model it this way:

• Year 1: about 10%
• Year 2: about 8%
• Years 3–5: about 5% / year
• Years 6–9: about 4% / year
• Year 10: ~12% (larger drop)
• Years 11–19: about 3% / year
• Year 20: ~10% (larger drop)
• Years 21+: about 3% / year

How updates are valued

Renovations don't return 100% of their cost. A $5,000 roof might add $3,000 of resale value at install. From there, that added value decays over the update's useful life.

The result: a recent roof offsets more of the year-10 or year-20 drop than one that's already 8 years old.

Two ways to use it

Already own the home? Enter what you paid originally, the year you bought it, and the year it was built. The tool shows today's value and where it's headed.

Considering a purchase? Enter today's asking price with this year as the purchase year. You'll see projected value in 10 and 20 years.
