Frequently Asked

How is a small business typically valued?

It’s an estimate based on your inputs (price, down payment, rate, taxes, insurance, HOA, PMI). It doesn’t include closing costs or maintenance. For a lender quote, you’ll need a pre-approval.

What’s in SDE?

Principal & Interest (mortgage), Property Taxes, Homeowners Insurance, HOA dues (if any), and PMI (when applicable). Utilities and maintenance are not included.

What multiples are common?

Use your municipality’s millage/percent rate and multiply by the home price (or assessed value if you know it). If you’re unsure, start with a conservative local average and refine with your agent or the county site.

Tip: Taxes vary by city/township and school district. Always verify with the county assessor or a current bill.

What about homeowners insurance?

Enter your expected annual premium (often a few hundred to a couple thousand dollars per year depending on coverage, age of home, and location). The calculator spreads it over 12 months.

Does this account for escrow?

Yes, if you include taxes and insurance, the monthly total reflects what an escrowed payment would look like (mortgage + tax/insurance portions).

Fixed vs. adjustable (ARM) rates—can I model that here?

This tool assumes a fixed rate. For ARMs, you can still test the initial rate period by entering that starting APR. For future adjustments, try a “what-if” by increasing the rate and comparing the new payment.

How do points or lender credits affect my payment?

Points lower your rate up front (higher closing costs, lower monthly). Credits raise your rate (lower closing costs, higher monthly). Adjust the APR field here to see the monthly impact, and compare closing costs with your lender.

What down payment should I choose?

There’s no one-size-fits-all. Larger down payments can reduce PMI and interest costs, but cash on hand might be better used for reserves or improvements. We’ll help you compare net outcomes for your goals.

Can I model extra principal payments?

This calculator shows the standard payment. To simulate paying extra, add your planned monthly extra to the Principal & Interest line to see a “total you’d pay,” or ask us for an amortization with prepayments.
