Picking the wrong mortgage lender can cost you tens of thousands of dollars over the life of a loan. The difference between a 6.5% and a 7.1% rate on a $400,000 mortgage is roughly $150 a month — and that adds up fast. Here's exactly how to compare mortgage lenders on rates, fees, and terms so you make a confident, informed choice.
Start With the APR, Not Just the Interest Rate
Most lenders advertise their interest rate prominently, but the Annual Percentage Rate (APR) tells the real story. The APR folds in origination fees, broker fees, and certain closing costs, giving you a single number that reflects the true cost of borrowing.
For example, a lender offering 6.75% with $4,000 in origination fees may actually cost more than a lender offering 6.9% with $500 in fees — especially if you plan to stay in the home for fewer than 10 years. Always request the APR alongside the interest rate and use both numbers together.
Decode the Fee Structure
Fees can vary dramatically between lenders, and they're often buried in the Loan Estimate document. When you apply, every lender is legally required to give you a Loan Estimate within three business days. Use it.
Key fees to compare:
- Origination fee: Typically 0.5%–1% of the loan amount. Some lenders charge zero, but offset it with a higher rate.
- Discount points: One point = 1% of the loan. Paying points buys down your rate — only worth it if you keep the loan long enough to break even.
- Underwriting fee: Can range from $400 to $900 depending on the lender.
- Third-party fees: Appraisal (~$500–$700), title insurance, and settlement fees are sometimes inflated by lender-preferred vendors.
- Prepayment penalty: Rare today but not extinct — confirm there isn't one.
Line up Loan Estimates from at least three lenders side by side on Page 2, Section A and B. That's where the fees live.
Compare Loan Types and Terms
Not all loans are built the same, and the right structure depends on your situation.
- 30-year fixed vs. 15-year fixed: A 15-year loan carries a lower rate (often 0.5%–0.75% less) but significantly higher monthly payments. Good if you can afford it and want to build equity fast.
- Adjustable-rate mortgages (ARMs): A 5/1 or 7/1 ARM starts lower than a fixed rate and can make sense if you plan to sell or refinance before the adjustment period kicks in.
- FHA vs. conventional: FHA loans allow down payments as low as 3.5% and accept lower credit scores, but you pay mortgage insurance for the life of the loan (unless you put 10% down). Conventional loans with 20% down avoid PMI entirely.
- Jumbo loans: For loans above $766,550 (2024 conforming limit in most areas), expect stricter underwriting and slightly higher rates.
Ask each lender to quote the same loan type and term so you're doing an apples-to-apples comparison.
Evaluate the Lender — Not Just the Numbers
Rate shopping is only half the job. A lender who's slow to process your file can blow up a deal in a competitive market.
Questions to ask every lender:
- What's your average time to close? (Benchmark: 21–30 days for purchase loans)
- Do you underwrite in-house or outsource it?
- Who will be my point of contact throughout the process?
- Are you a direct lender or a broker? (Brokers shop multiple wholesale lenders on your behalf, which can get you better pricing but adds a middleman.)
- Can you lock my rate, and for how long? (30, 45, and 60-day locks are standard; longer locks cost more)
Check reviews on Google, Zillow, and the NMLS Consumer Access database to verify licensing and spot any disciplinary history.
Use a Structured Comparison Process
The most common mistake buyers make is getting one quote, assuming it's reasonable, and moving on. Rate shopping within a 45-day window won't hurt your credit score — all mortgage inquiries in that period count as a single hard pull under FICO scoring models. There's no financial reason not to get four or five quotes.

A practical comparison checklist:
- Request Loan Estimates from at least 3–5 lenders on the same day (same loan amount, type, and term)
- Compare APR, total closing costs, and monthly payment side by side
- Check the lender's track record on turnaround times and reviews
- Negotiate — lenders will often match or beat a competitor's Loan Estimate
- Lock your rate once you've chosen, and get it in writing
