01
Where to start
If you're just beginning, read the first-time buyer guide and the glossary. If you're comparing prices, use the calculators. If you're getting ready to apply, go through the checklist so you know what information is usually needed.

Planning tools and what they can't do
The payment and affordability calculators run entirely in your browser. They show estimates based on your own assumptions, including the interest rate you enter. They can't account for your credit, pricing, program rules or underwriting.

When to talk to someone
If your situation includes self-employment, variable income, a rural or unusual property, VA eligibility or a move from another state, a short conversation with a mortgage professional is often more useful than more reading.
