How the numbers are checked
Mortgage, LTV and property-tax calculations live in one tested calculation engine. External rules and illustrative assumptions are traced to primary sources and reviewed before releases.
What the site does not do
It does not decide whether a lender will approve you, recommend a mortgage or store an application. The results are planning illustrations.
