About
About This Website
Buying, renting, or refinancing a home usually comes down to advice dressed up as certainty — a lender says you qualify, a friend says renting wastes money, an agent says now's the time. HomeDecisionIQ exists to show the actual math behind those tradeoffs, so the decision is visible instead of implied.
How These Calculators Are Built
Every calculator here is built on a transparent research and review process. The tools draw from HUD homebuying guidance, CFPB mortgage and housing resources, and homebuyer education materials from Fannie Mae and Freddie Mac. Where sources don't fully agree, that disagreement is researched before an approach is chosen.
Before publishing, every calculator goes through multiple rounds of review: calculations verified, assumptions challenged, edge cases tested. Independent review tools, including AI-assisted analysis, help catch inconsistencies or outdated figures before anything goes live.
Why the Assumptions Are Visible
A lender's approval number and a comfortable monthly budget are different things, and most tools blur the line. Every input that shapes a result here — interest rate, tax estimate, insurance assumption — is shown openly and can be adjusted to match your actual situation.
Educational Information — Not Professional Advice
This is an educational planning tool. It's built to help you walk into a conversation with a mortgage broker or real estate agent already understanding your own numbers.
A Commitment to Improvement
Mortgage rates, tax rules, and lending guidance change over time. If something here looks outdated or wrong, feedback can be sent to hello@answerworth.com.
Don't trust a result simply because it appears on this website. Trust it because you can see how it was calculated, examine the assumptions, and decide for yourself whether the reasoning fits your situation.
