Data collection and review process
NerdWallet currently reviews more than 40 mortgage lenders, including the majority of the largest U.S. mortgage lenders by annual loan volume (measured among lenders with at least a 1% market share); lenders with significant online search volume; and those that specialize in serving various audiences across the country. Some of these lenders are NerdWallet partners, but this does not influence the review process.
We collect information from lenders and verify it through our independent research. We analyze Home Mortgage Disclosure Act (HMDA) data for APR spread, market share, product distribution, and loan type information, and we reference internal performance data when available.
Then, we rate the lenders on a scale of 1 to 5 stars based on their scores on the following criteria: rates and fees (APR spread), product accessibility, customer experience, rate transparency to consumers and variety of loan types. Each category constitutes a portion of the lender’s overall score. Lenders’ raw scores may receive bonuses for programs or policies that expand homeownership opportunities. Their raw scores may be penalized in cases of recent regulatory action for violations that harmed mortgage consumers. These scores generate ratings from 1 star (poor) to 5 stars (excellent). Lenders score higher for having lower rates and fees, making products accessible across the U.S. and to a range of financial profiles, offering comprehensive customer support from application to close, allowing consumers to easily compare mortgage rates online, and offering a wider variety of loan products.
