Modular Building Valuation Made Simple
If you own a modular building, portable classroom, or mobile office trailer and are wondering, “What’s it worth?”, you’re not alone. At iModular.com, we hear this question daily from facility managers, church administrators, business owners, and school officials across the U.S.
That’s why we built the Modular Building Valuation Calculator — a free, easy-to-use tool designed to estimate the resale, donation, or insured value of any used modular structure.
You can jump directly to the calculator here, but we suggest reading about it first.
Why Accurate Valuation Matters
Knowing the fair value of your modular building is essential whether you’re planning to:
- 💰 Sell your unit on the private market or through a broker
- 🎁 Donate it to a school, nonprofit, or church for tax benefits
- 🧾 Insure the structure as part of a facility portfolio
- 🧮 Appraise it for internal budgeting or asset management
Unfortunately, there’s no Kelley Blue Book for modular buildings — until now.
How The Calculator Works
The iModular.com calculator utilizes industry-standard depreciation schedules, aligned with data from the Modular Building Institute (MBI), and incorporates real-world resale data from our 30+ years of experience in the field.
Here’s what it considers:
| Input | How It Affects Value |
|---|---|
| Year Manufactured | Determines depreciation based on 15-year useful life |
| Original Purchase Price | Establishes baseline value |
| Building Size | Impacts marketability |
| Condition Rating | Adjusts value for wear and tear |
| Floor Plan Features | Adds resale value for bathrooms, kitchens, offices, HVAC, etc. |
What Makes Our Calculator Unique
Unlike generic construction cost estimators or spreadsheets used by insurance agents, our calculator is built specifically for modular buildings — including:
- Portable classrooms
- Jobsite office trailers
- Church buildings
- Modular locker rooms
- Temporary healthcare clinics
- Mobile banks and field offices
We also understand the nuances of the secondary market: a well-maintained 24’x60′ classroom with dual restrooms and ramps in California has a very different resale profile than a gutted jobsite trailer in Texas.
How to Use the Calculator
- Enter the original purchase price (or your best estimate)
- Enter the year the building was manufactured (or guess)
- Select the condition
- Check off features like bathrooms, HVAC, or break rooms
- Get your estimated resale value instantly
You can use this value to set a sale price, determine a donation write-off, or support an insurance quote.
Deciding to sell, donate, or possibly remodel and re-use a used portable classroom can be a tricky decision.
