How to Choose a Mortgage Lender: 7 Key Factors
Last updated: October 2026 · Editorial standards
The difference between lenders can cost or save you thousands of dollars on your mortgage. Here are the seven factors that matter most when choosing where to borrow.
Factor 1: Interest Rate (and APR)
The interest rate determines your monthly payment. But the rate alone doesn’t tell the full story — look at the Annual Percentage Rate (APR), which factors in the rate plus fees to give you the true cost of borrowing.
Never compare rates without also comparing fees. A lender offering a rate 0.125% lower might offset that advantage with $3,000 in additional origination fees.
What to do: Get Loan Estimates from 3+ lenders on the same day (rates change daily) and compare both rate and APR.
Factor 2: Fees and Closing Costs
Lender fees include:
- Origination fee (sometimes called origination points)
- Underwriting fee
- Application fee
- Processing fee
These fees vary significantly between lenders — sometimes by thousands of dollars for identical loan amounts. Some online lenders have lower overhead and charge less.
What to do: Compare Section A (origination charges) on each Loan Estimate. These are fees the lender directly controls.
Factor 3: Loan Programs Offered
Not every lender offers every loan type. Some specialize in conventional loans; others focus on FHA and VA. Some offer portfolio products for unusual situations.
Make sure the lender offers the specific program you need:
- FHA loans for lower credit scores
- VA loans if you’re a veteran
- USDA loans for eligible rural areas
- Jumbo loans for high-value properties
- Construction loans if building
What to do: Confirm the lender is approved for your specific loan type before going far in the process.
Factor 4: Lender Reputation and Reviews
Reviews from past borrowers reveal how lenders handle the process when things get complicated — which they often do.
Look for:
- Reviews on Zillow, Google, Bankrate, and the CFPB complaint database
- Complaints filed with your state’s banking regulator
- BBB ratings
- Testimonials from buyers who used the same loan type you’re pursuing
Pay attention to reviews mentioning communication, closing timeline adherence, and how problems were handled.
Factor 5: Communication and Responsiveness
Your lender is your partner through one of the most stressful financial transactions of your life. Responsiveness matters enormously.
Warning signs during lender shopping:
- Takes more than 24 hours to return calls or emails
- Unclear or evasive answers to direct questions
- Oversells and undersells potential problems
- Can’t clearly explain their fees
What to do: Test responsiveness during shopping — call with a question and see how quickly and clearly they respond.
Factor 6: Estimated Closing Timeline
Ask specifically: “What is your average time from completed application to clear to close?”
Some lenders have high volume and slow underwriting. Others have efficient processes and close in 21–30 days. If your purchase contract has a tight closing deadline, timeline matters as much as rate.
Local lenders and mortgage banks often have faster processing than large retail banks with central processing departments.
Factor 7: Loan Servicing
Most mortgages are sold to other servicers after closing. Your lender might originate your loan but never actually service it — Fannie Mae or a third-party servicer will collect your payments.
Ask the lender:
- “Do you service loans in-house or sell them?”
- “Who will service my loan after closing?”
If you prefer to keep a relationship with a local bank or credit union and have them service your loan long-term, confirm that before choosing.
The Bottom Line: Get at Least 3 Loan Estimates
CFPB research shows that getting just one additional mortgage quote saves an average of $1,500. Getting 5 quotes saves an average of $3,000.
The time investment — a few hours — has one of the highest returns of anything you’ll do in the home buying process.
Key Takeaways
Rate gets the attention, but fees, program availability, responsiveness, and timeline are equally important. Get multiple Loan Estimates, compare them systematically, and don’t choose a lender based on a single number.
Frequently Asked Questions
Does shopping multiple lenders hurt my credit score? No — multiple mortgage inquiries within a 14–45 day window (depending on the scoring model) are treated as a single inquiry. Shop freely.
Should I use the lender my real estate agent recommends? Consider their recommendation but get other quotes too. Agents sometimes have relationships with lenders — your interests may not perfectly align.
Is a local lender better than a national one? Not automatically. Local lenders often have better service and faster processing. National lenders sometimes have lower rates due to volume. Evaluate each on the 7 factors above.
What documents do I need to apply at multiple lenders? The same documents for each: tax returns, pay stubs, W-2s, bank statements, ID. Once you’ve assembled the package once, sharing it with multiple lenders takes minimal additional effort.
