Choosing a mortgage lender is as important as choosing the loan type itself — the same borrower can receive meaningfully different rates and fees from different lenders. This guide gives you a framework for evaluating lenders properly, based on what genuinely matters rather than brand recognition or advertising.

A note on how we approach this topic

MyHomeRates.com has no relationships with any mortgage lender, and we don't recommend or rank specific companies. This guide teaches you the evaluation framework to use yourself, so you can make an informed, independent comparison of whichever lenders you're considering.

1. Types of mortgage lenders

Banks and credit unions

Traditional institutions, often offering relationship discounts if you have existing accounts. Credit unions sometimes offer more favourable terms to members but may have more limited loan product variety.

Mortgage brokers

Don't lend directly — they shop your application across multiple wholesale lenders on your behalf. Can save time comparing, but confirm how the broker is compensated, as this can sometimes influence which lender they steer you toward.

Direct/online lenders

Lend directly without a broker intermediary, often with streamlined digital applications. Lower overhead can sometimes translate to competitive rates, though this varies by company.

Mortgage companies

Specialise solely in mortgage lending rather than offering broader banking services. Often have deep product knowledge across many loan types including niche programs.

2. What actually differs between lenders

For an identical borrower profile, lenders can differ meaningfully on:

3. Questions worth asking every lender

What is my interest rate and APR — and what's the difference between them on this specific quote?
What are the total estimated closing costs, itemised?
Is this rate locked, and for how long? What happens if closing is delayed past the lock period?
What's your typical time to close from application to funding?
Will my loan be serviced by you, or sold to another company after closing?
Are there any prepayment penalties on this loan?

4. How to compare offers properly

Every lender is required to provide a standardised Loan Estimate within three business days of application, under CFPB regulations. This document uses the same format across all lenders specifically to make comparison easier — use it.

Compare on the same day, for the same loan terms

Rates fluctuate daily. Get all your quotes within the same 1-2 day window, and ensure each quote reflects identical loan terms (same rate type, term length, and points) so you're making a true apples-to-apples comparison.

5. Worked example — comparing three quotes

Worked example
Same borrower, three lender quotes, same day
3 Quotes compared
$310,000 Loan amount
0.45% Rate spread

Lender A: 6.75% rate, $4,200 in fees, APR 6.91%

Lender B: 6.50% rate, $6,800 in fees, APR 6.78%

Lender C: 6.30% rate, $9,100 in fees, APR 6.71%

Lender C has the lowest headline rate, but once fees are factored into the APR, the gap between Lender B and Lender C narrows significantly. Whether C is genuinely the better choice depends on how long the borrower plans to keep the loan — the higher upfront fees take longer to "pay back" through the lower rate. For a borrower planning to stay 10+ years, Lender C likely wins; for a shorter horizon, Lender A's lower fees may actually be cheaper overall.

Frequently asked questions

It's worth getting a quote from your existing bank — some offer relationship discounts for account holders — but don't assume they'll automatically offer the best rate. Always compare against at least two other lenders.
Your loan terms (rate, payment, term) cannot change when serviced by a different company — this is protected by federal regulation. It mainly affects where you send payments and who you contact for service questions. It's common practice and not generally something to avoid a lender over, though some borrowers prefer lenders who retain servicing.
Legitimate online mortgage lenders are regulated the same way traditional lenders are. Verify any lender is properly licensed in your state via the Nationwide Multistate Licensing System (NMLS) — every legitimate mortgage lender and loan officer has an NMLS number, which should be disclosed in their communications and marketing.
A Loan Estimate reflects pricing at the time it was issued, typically valid for 10 business days for you to indicate intent to proceed. The actual rate is usually not locked until you explicitly request a rate lock, which is a separate step.
