What matters most when comparing mortgage lenders
The lender you choose affects your interest rate, closing costs, how fast you close, and how much support you get during the process. Three things matter most: the interest rate they quote you, the fees they charge, and whether they can actually close on time. A lender with a slightly higher rate but lower fees and faster closing might cost you less money overall than one with the lowest advertised rate.
You are not locked into the first lender you talk to. Getting quotes from at least three lenders — a bank, a credit union, and a mortgage broker — takes a few hours and can save you thousands of dollars over the life of the loan. Each lender will pull your credit and ask about your finances, but these inquiries within a 14-day window count as a single credit check, so shopping around does not hurt your score.
Key Takeaways
- Compare the Loan Estimate from at least three lenders, which shows the interest rate, all fees, and the total amount you will pay over the loan term.
- Banks, credit unions, and mortgage brokers each have different rate structures and fee schedules — getting quotes from all three types usually finds the best deal.
- The interest rate matters, but so do origination fees, appraisal costs, and title insurance — add them all up before deciding.
- Ask each lender about their typical closing timeline and whether they service the loan themselves or sell it after closing, because that affects your experience later.
Understanding the Loan Estimate and what to compare
Federal law requires every lender to give you a Loan Estimate within three business days of your process. This document shows your interest rate, all fees broken down by line item, the loan amount, the term, and the total amount you will pay over the life of the loan. This is the only document you need to compare lenders fairly — do not rely on phone quotes or emails.
The Loan Estimate has three main sections. The first shows the loan terms: the principal amount, interest rate, and monthly payment. The second lists all costs you will pay at closing, separated into what the lender charges (origination fee, processing fee, underwriting fee) and what third parties charge (appraisal, title insurance, recording fees). The third shows your total cost of borrowing — the sum of all payments plus all fees. When you compare Loan Estimates side by side, you can see exactly which lender costs the least.
Some fees are negotiable, especially the origination fee and processing fee. If one lender's rate is higher but their fees are lower, you can ask a lower-fee lender to match the rate or reduce their fees. Lenders compete for your business, and they know you are shopping around.
Banks, credit unions, and mortgage brokers — what each offers
Banks are the largest lenders and have the most loan products. They typically have competitive rates because they have low cost of funds, but they also have higher overhead. Banks service most of their own loans, meaning you will pay them every month after closing. If you value consistency and dealing with the same institution, a bank is straightforward.
Credit unions usually offer lower rates to their members because they are nonprofit and pass savings back to borrowers. You must be a member to borrow from them, but membership is often free or costs a small deposit. Credit unions tend to have simpler fee structures and more flexibility on credit score requirements. The downside is that credit unions have fewer loan products and may not offer specialized mortgages like jumbo loans or investment property financing.
Mortgage brokers do not lend money themselves — they connect you with lenders and earn a commission from the lender you choose. This means brokers have access to dozens of lenders and can shop your process across multiple sources at once. Brokers are useful if you have a complicated financial situation, a lower credit score, or need a specialized loan type. The risk is that a broker's incentive is to close the loan, not necessarily to get you the best deal, so you still need to compare their final Loan Estimate against direct quotes from banks and credit unions.
Interest rates, points, and how to compare them fairly
The interest rate you are quoted depends on several factors: the current market rate, your credit score, your down payment size, the loan term, and the type of property. A lender might offer you a lower rate if you pay points — an upfront fee equal to a percentage of the loan amount. One point costs 1% of the loan and typically lowers your rate by 0.25%. This makes sense if you plan to stay in the house for many years, but not if you might sell or refinance soon.
When comparing rates across lenders, make sure you are comparing the same loan type: a 30-year fixed rate, for example, not a mix of 30-year and 15-year quotes. Ask each lender for their rate on the same day, because rates change hourly. A rate quote is usually good for 30 to 45 days, so you have time to decide, but the rate can lock in only when you formally lock it with the lender.
Some lenders advertise a very low rate but charge high fees to make up for it. Others advertise low fees but charge a higher rate. The Loan Estimate shows the true cost of each option. Calculate the total amount you will pay (all monthly payments plus all fees) and compare that number across lenders, not just the rate.
Closing timeline and loan servicing — what happens after you sign
Most lenders close loans in 30 to 45 days, but some close faster and some slower. If you are on a tight timeline — your lease ends, your current home sale closes on a specific date — ask each lender how many loans they close per week and whether they have ever missed a closing important date. A lender who closes 50 loans a week is more likely to stay on schedule than one who closes 5.
After closing, your loan will be serviced by someone — the lender you borrowed from, or a different company that bought the loan. Some lenders service all their loans; others sell most of them. This matters because you will send your monthly payment to the servicer, and if you have a problem with your account, you contact the servicer. Ask each lender whether they service their own loans or sell them, and if they sell, whether they sell most loans or only some. A lender who services their own loans gives you continuity, but a lender who sells loans is not necessarily worse — you just need to know what to expect.
Red flags and what to avoid
Avoid any lender who pressures you to explore before you have seen a Loan Estimate, who quotes a rate without asking about your finances, or who promises a rate that seems too good to be true. Rates change daily, and a lender who quotes you a rate significantly lower than what you see elsewhere is either not being honest or is planning to charge you in fees instead.
Do not sign anything until you have reviewed the Closing Disclosure, which you receive at least three business days before closing. This document is similar to the Loan Estimate but shows the final numbers. If the Closing Disclosure differs significantly from the Loan Estimate, ask the lender why before you close. Some small changes are normal, but large changes are a sign something went wrong.
Be cautious of lenders who do not have a physical office or a clear way to contact them. Mortgage lending is regulated, and every lender must be licensed in your state. You can verify a lender's license through your state's banking regulator or through the Nationwide Multistate Licensing System (NMLS). If you cannot find them there, they are not legitimate.
How to organize your comparison and make a decision
Create a straightforward spreadsheet with the lenders you are comparing. List the interest rate, origination fee, appraisal cost, title insurance, closing costs total, and the total amount you will pay over the loan term. Add a column for closing timeline and whether they service their own loans. This visual comparison makes the decision much clearer than trying to remember phone conversations.
Once you have narrowed it down to your top choice, lock in your rate with that lender. A rate lock guarantees that rate for a set number of days, usually 30, 45, or 60. After you lock, the lender will order the appraisal and begin the underwriting process. You can still back out if something changes, but the rate is now protected from market swings.
The cheapest lender is not always the best choice if their closing timeline is too tight or if you feel uncomfortable with their communication. You are going to work with this lender for the next month or more, so pick one you trust and who responds to your questions promptly.
Frequently Asked Questions
Does shopping around for mortgage rates hurt my credit score?
Multiple credit inquiries from mortgage lenders within a 14-day window count as a single inquiry, so your score drops only a few points and recovers within a few months. Shopping around is worth the temporary dip because the rate difference between lenders can cost you tens of thousands of dollars over time.
What is the difference between a mortgage broker and a bank?
A bank lends its own money and services most loans. A broker connects you with lenders and earns a commission. Brokers can access more loan products and are useful for complicated situations, but you still need to compare their final quote against direct bank and credit union quotes.
Can I negotiate the interest rate or fees?
Yes. Origination fees, processing fees, and some third-party fees are negotiable. If one lender has a higher rate but lower fees, ask them to match the rate or reduce fees. Lenders know you are shopping around and will often adjust to keep your business.
What if I have a lower credit score — does that limit my lender options?
Most banks require a credit score of 620 or higher, but credit unions and some mortgage brokers work with lower scores. You will pay a higher interest rate, but you still have options. Get quotes from multiple lenders because rates vary widely for borrowers with lower scores.
Should I lock in my rate right away or wait to see if rates drop?
Rate locks protect you from increases but also prevent you from benefiting if rates fall. Most lenders offer a 30 to 45-day lock, which is usually long enough to close. If rates are historically high and you are not sure, wait a few days to see the trend, but do not wait so long that you run out of time to close on your important date.
