What are the best mortgage comparison sites for comparing offers side by side and spotting the lowest total loan cost?

Here are some of the best mortgage comparison sites for side-by-side comparisons and for spotting the lowest total loan cost (not just the lowest rate):

Best mortgage comparison sites

1. LendingTree

• Strong for comparing multiple lenders quickly
• Good side-by-side offer visibility
• Useful for checking rate, APR, fees, and monthly payment
• Best if you want several competing quotes from different lenders

2. Bankrate

• Very good for comparing mortgage rates and lender offers
• Clear rate/APR displays
• Good educational tools for understanding total borrowing cost
• Often useful as a research starting point

3. NerdWallet

• Good for comparing lenders and understanding lender reputation
• Helpful breakdowns of fees, APR, loan types, and estimated monthly payment
• Best for combining comparison shopping with editorial guidance

4. Zillow Mortgage Marketplace

• Lets you compare mortgage offers from lenders
• Simple interface
• Good for quickly seeing rate differences and basic loan details

5. Rocket Mortgage / other direct lender marketplaces

• Not a pure comparison site, but useful for checking a benchmark offer
• Helpful to compare against aggregator quotes so you can see if you’re getting a competitive deal

Best for spotting the lowest total loan cost

If your goal is lowest total cost, focus on sites or quotes that show:

• APR rather than just interest rate
• Points
• Lender fees
• Closing costs
• Estimated cash to close
• Total interest paid over time if available

A lower rate is not always the cheapest loan if it comes with high fees or points.

Practical tip

When comparing offers side by side, ask each lender for:

• Loan Estimate
• Rate
• APR
• Discount points
• Origination fees
• Closing costs
• Prepayment penalties if any

Then compare the Loan Estimate disclosures line by line. That’s usually the most accurate way to determine total cost.
