Guides & affordability

Is a mortgage a loan?

Yes - and this explains how mortgages differ from other loans because the home is collateral.

How long do mortgages last?

Compare 15 vs 30-year terms, the payment tradeoff, and how refinancing or extra payments change the timeline.

Want the most accurate monthly payment?

Start with your loan amount, rate, and term - then add taxes, insurance, PMI, and HOA so your estimate matches real-world housing costs.
