See how your current payment compares.
You're already paying every month. The question is what it's building.
What are you paying now?
Your $2,400/month could become a ~$1,999/month loan payment — less than you pay now — while building an asset you own.
| Keep paying rent | Build a KĒĒP ADU | |
|---|---|---|
| Monthly payment | $2,400 | ~$1,999 |
| Monthly difference | — | $401 less per month |
| After 10 years | $288,000 spent, nothing owned | Loan paid down + ~$31,200 equity gained |
| What you own at the end | Nothing | An appreciating asset on your own land |
Equity gained is an estimated increase in your property's value (roughly 12% of build cost) — typically less than the full build cost. Loan payment assumes financing the full build cost at an estimated 8.5% rate over 30 years — verify with a lender.
Want these numbers run for your actual property and situation? A free 48-Hour Property Check — no cost, no obligation.
Check my propertyThis is an illustration of how your current monthly payment compares to an ADU loan payment — not financial advice or a guarantee of returns. Loan payment assumes financing the full build cost at an estimated rate; your actual rate, terms, and equity depend on your lender, your property, and market conditions. Consult a lender and tax professional. KĒĒP's fixed price is confirmed in writing after a free 48-Hour Property Check and site assessment.
