Most cost comparisons between modular and stick-built homes are fundamentally wrong.

They compare the sticker price — the build contract, the materials, the labor. And on paper, modular often looks like it's only 10-15% cheaper.

But here's what almost nobody factors in: carrying costs during construction.

The Math Nobody Does:

Stick-built timeline: 8–14 months (national average: 10.5 months)

Modular timeline: 3–5 months (national average: 3.8 months)

That's roughly 7 extra months of:

• 🏦 Construction loan interest (typically 7-9% on drawn funds)

• 🏠 Rent or mortgage on your current home

• 📦 Storage unit fees

• 🔒 Insurance on an unfinished structure

• 💰 Property taxes from the moment you close on land

On a $350K build, those 7 months of carrying costs add $18,000–$28,000 that never shows up in any contractor's bid.

When you add carrying costs back into the equation, modular doesn't just win by 10%. It wins by 23-31% on total out-of-pocket cost.

This Is Just One of 12 Cost Categories

In my Modular vs Stick-Built Mastery course, I break down every hidden cost category, give you the exact formulas to run your own comparison, and walk you through a decision framework used by professional owner-builders and real estate investors.

If you're within 18 months of a build decision, this analysis will save you more than it costs in the first lesson.
