Terms of use

Last updated October 8, 2026

By using OK Home Math you agree to these terms. If you don't agree, please don't use the site.

What the site is for

The calculators and pages are for general education about buying a home in Oklahoma. Estimates for education only. Not a loan offer, not lending, tax, legal or financial advice. Rates and limits change; confirm with a licensed lender, OHFA, and your county assessor. See the disclaimer.

Accuracy

We work to keep every figure tied to a dated public source and every formula documented on the methodology page, but we don't guarantee that the site is complete, current or error-free. You use the results at your own risk, and you are responsible for decisions you make.

Content and data

The site's text, design and code belong to OK Home Math. Public data shown here belongs to its publishers and is credited on each page. Freddie Mac Primary Mortgage Market Survey® figures are shown unaltered with attribution, as Freddie Mac requires. You may link to any page and share calculator links freely.

Acceptable use

Don't attempt to disrupt the site, overload it with automated requests, or present its estimates to others as offers, quotes or advice.

We link to government agencies and other sources. We don't control those sites and aren't responsible for their content or practices.

No warranty; limitation of liability

The site is provided “as is” without warranties of any kind. To the fullest extent the law allows, OK Home Math is not liable for any loss or damage arising from use of the site or reliance on its estimates.

Changes

We may update these terms. The date at the top shows the latest version; continuing to use the site means you accept it.
