How to use this hub
Pick the tool by task, then check the assumptions.
Category pages are meant to be useful on their own, not just lists. These notes explain what the group covers, where the limits are, and which pages deserve extra care.
Higher-risk pages such as mortgage affordability, mortgage vs rent, paycheck, tax estimate, and DTI include source notes or visible warnings where the assumptions need extra context.
The outside rules that matter depend on the tool: lender terms, tax rules, payroll settings, insurance, local fees, credit profile, and payment timing can all change the real number.
