Picking the wrong mortgage lender can cost you thousands of dollars and months of stress. I’ve been working with buyers for over 40 years, and the mistakes I see most often aren’t about the house, they’re about choosing the lender. Here’s exactly what to look at, what to ask, and what to walk away from.
Step 1: Get Your Financial House in Order First
Before you talk to a single lender, you need to know your numbers. Not a rough estimate. Your actual numbers.
Start with your credit score. Pull your report from a trusted credit reporting resource so you understand what lenders will see. A score above 740 usually gets you the best conventional rates. Below 620, and you’re likely looking at FHA territory, which isn’t bad, just different.
Next, look at your debt-to-income ratio, or DTI. Add up all your monthly debt payments, then divide that number by your gross monthly income. Most conventional lenders want to see that number at or below 43%. Some will push to 50% with strong compensating factors, but the lower your DTI, the better your options.
Then figure out your down payment. A larger down payment does two things. It lowers your monthly payment, and it eliminates private mortgage insurance (PMI) if you can get to 20% of the purchase price. PMI is only required on conventional mortgages when your loan-to-value ratio is above 80%, so that 20% threshold matters.
Apply what old-timers call the 28/36 rule. Your mortgage payment shouldn’t exceed 28% of your gross monthly income. And your total debt load, mortgage plus everything else, should stay under 36%. Lenders use variations of this, but the principle is sound regardless of the market.
One more thing before you call a lender: gather your documentation. Two years of W-2s and tax returns. Two months of bank statements. Pay stubs from the last 30 days. If you’re self-employed, add your profit and loss statement and your business tax returns. Having these ready speeds everything up and signals to lenders that you’re serious.
Step 2: Understand the Types of Lenders Available to You
Most buyers call the bank they’ve used for years and stop there. That’s a mistake. You have more options than you think, and the right type of lender depends heavily on your situation.
Traditional banks and credit unions are familiar. They hold your deposits, they know your transaction history, and they sometimes offer relationship discounts. Credit unions in particular often pass savings to members in the form of lower fees. The downside is that big banks move slowly and their loan programs tend to be rigid.
Mortgage brokers don’t lend their own money. They shop your file across dozens of wholesale lenders and bring you the best match. A good broker can find programs you’d never discover on your own, especially if your financial profile is a little outside the standard box. They earn a commission from the lender, which is disclosed upfront.
Non-bank lenders have grown significantly since the Great Recession. Many operate online, which means lower overhead and sometimes lower rates. They’re not affiliated with a depository bank, but they’re licensed and regulated. Non-bank lenders have become increasingly important to how the mortgage market functions, and dismissing them because you don’t recognize the name is a common and costly mistake. Research cited by MortgageCalculator.org confirms they now handle a substantial share of all loan originations.
Beyond lender type, you also need to understand loan types. FHA loans allow as little as 3.5% down and have more flexible credit requirements. VA loans let eligible veterans purchase with no money down. USDA loans serve buyers in qualifying rural areas, also with zero down. Conventional loans are the most common, and some conventional programs require as little as 3% down for income-qualifying buyers. For a deeper look at how these stack up, our conventional vs. FHA loan comparison walks through eight specific loan structures side by side.
There’s also something worth knowing about assumable mortgages. Most conventional loans aren’t assumable, but most VA and FHA loans are. That means a buyer can take over the seller’s existing mortgage and keep the rate the seller locked in years ago. If a seller locked in a rate around the time of the COVID-19 lockdowns when rates were low, an assumable mortgage can save you tens of thousands over the life of the loan. It’s a little-known option that most buyers never ask about.
Step 3: Compare Lenders on Rates, Fees, and Loan Estimates
This is where most buyers get it wrong. They ask for a rate quote, hear a number, and assume that settles it. It doesn’t. The rate is just one piece of the cost.
What you actually want to compare is the APR, the annual percentage rate. APR bundles the interest rate and most lender fees into a single figure, which makes it possible to compare two lenders on equal terms. A lender quoting 6.5% with $5,000 in fees may cost more over five years than a lender quoting 6.7% with minimal fees. You can’t see that without APR.
Shopping with multiple lenders can save you over $1,000 a year, according to research from Freddie Mac. Most buyers talk to one lender and move on. Talk to at least three before you decide.
When you request quotes, ask each lender to quote you with zero discount points. Discount points are prepaid interest, you pay money upfront to buy your rate down. Comparing a no-point rate from one lender to a one-point rate from another is like comparing apples to grapefruit. Get the baseline rate from everyone first. Then ask separately how much each point reduces your rate so you can run the math on your own break-even timeline.
Once you’re under contract, every lender is legally required to give you a Loan Estimate within three business days. This is a standardized form, three pages, same format from every lender. Page one shows your rate, loan amount, and projected monthly payment. Page two breaks costs into three sections. Section A lists origination charges, this is where lender fees live, and it’s the most negotiable section. Section B covers services you can’t shop (appraisal, credit report). Section C covers services you can shop (title, settlement).
Read Section A carefully. A processing fee, an underwriting fee, and a loan origination fee can each run $1,000 to $2,000. They’re real costs, and they vary meaningfully between lenders. Don’t overlook them because you’re focused on the rate.
Fixed-rate mortgages are what most buyers should choose. Your payment stays the same for the life of the loan, which makes budgeting predictable. Adjustable-rate mortgages can make sense in specific situations, mainly if you’re certain you’ll sell or refinance before the rate adjusts, but for most people buying a long-term home, a fixed rate is the safer call.
Step 4: Know the Difference Between Pre-Qualification and Pre-Approval
These two terms get used interchangeably, and they absolutely should not. They mean very different things, and in a competitive market, the difference can cost you a house.
Pre-qualification is a rough estimate. A lender asks you a few questions about your income and debts, does a soft credit pull (which doesn’t affect your score), and gives you a ballpark number. It takes about ten minutes. It also means almost nothing. A seller’s agent who sees a pre-qualification letter knows it’s unverified.
Pre-approval is different. The lender collects your actual documents, tax returns, pay stubs, bank statements, runs a hard credit pull, and reviews your file the way an underwriter would. What comes out the other side is a real number based on verified information. In Texas, when I’m helping a buyer write an offer, I always want them to have a full pre-approval letter, not a pre-qual. Sellers take pre-approved buyers seriously. Sellers see pre-qualified buyers as maybes.
There’s also a third level some lenders offer: credit approval or full underwriting before a property is selected. The lender reviews everything and issues a conditional approval, the only thing missing is the property itself. This is as close to a cash offer as a financed buyer can get, and it’s a meaningful advantage in a competitive situation.
One usable note: a hard credit pull from a mortgage lender does affect your score, but the credit bureaus understand that rate shopping is normal. Multiple hard pulls from mortgage lenders within a 14 to 45 day window are typically counted as a single inquiry. So don’t let the fear of a credit hit stop you from getting real pre-approvals from two or three lenders. The benefit of finding the better rate far outweighs a small temporary dip in your score.
For buyers relocating to Texas from another state, getting pre-approved by a Texas-licensed lender specifically can strengthen your offer, sellers here see that as a sign you understand the local market. Our guide to handling the mortgage application process for Austin homebuyers covers what that paperwork typically looks like from start to finish.
Step 5: Ask the Right Questions Before You Commit
Before you hand your business to any lender, ask them these questions directly. How they answer tells you as much as what they say.
How long is my rate lock, and what does it cost to extend it? Rate locks typically run 30 to 60 days. If your closing takes longer, which happens, and rates have moved up, you’ll pay to extend. Know that cost upfront.
At what point can I lock my rate? Most lenders won’t lock until you’re under contract. That’s standard. But if a lender says they won’t even discuss rates until you’re in contract, that’s a problem. A lender who can’t give you a general sense of where rates are today is either hiding something or doesn’t want the comparison.
What’s your typical closing timeline? A lender who routinely closes in 21 days is more useful in a competitive offer situation than one who needs 45. Ask what their actual average is, not their optimistic best case.
Who do I call if something goes wrong during underwriting? You want a direct line to a human being, a specific loan officer, not a call center. If the lender’s answer is “submit a ticket through the portal,” think carefully about whether that works for you when a closing date is on the line.
Are you licensed in this state and property type? This matters more for investors than traditional buyers, but it’s worth confirming. Some lenders can’t do loans on properties in certain conditions (major fixer-uppers, for example) or in certain states. Verify your loan officer’s license through the NMLS Consumer Access database, it’s public, free, and shows you exactly how long they’ve been licensed and where.
Also look up reviews. Check Google, Zillow, and Yelp, but that mentions the specific loan officer you’re working with, not just the company. A company with 500 five-star reviews doesn’t help you if your loan officer just got licensed six months ago.

Step 6: Watch for Red Flags and Misleading Promises
I’ve been in this business long enough to have seen most of the plays. Some of them are obvious. Others feel reasonable until you know what to look for.
The “lowest rate guaranteed” pitch. No lender can honestly guarantee they have the lowest rate in the market every single day. Rates shift constantly, and different lenders price loans differently based on the type of loan, the borrower profile, and how much business they’re chasing. A lender who makes that claim is making one you can’t verify, and probably shouldn’t trust.
The rate-match game. Some lenders say they’ll match any rate you find. Think about that for a second. If they can match it, why aren’t they offering it upfront? You shouldn’t have to do all the shopping so that a lender meets you at the finish line. A straightforward lender gives you their best offer from the start.
The rate that can’t be locked. I’ve heard from buyers who were quoted an impressive rate, then told the lender couldn’t lock it yet, they needed more documents, or the debt-to-income was suddenly an issue, or there was one more thing required. By the time the issues resolved, the rate had moved. Don’t celebrate a rate you can’t lock in writing.
A lender who doesn’t communicate directly with you. If your real estate agent is the one passing documents to the lender, and you’re not in direct contact with your loan officer, that’s a problem. You need a relationship with your lender. You need to be able to ask questions and get straight answers without going through an intermediary.
Vague answers about fees. If a lender can’t tell you what their origination fees are before you apply, they either don’t know their own product or they’d rather you not know. Either way, walk away. Good lenders are transparent about costs from the first conversation.
Many buyers automatically dismiss lenders they’ve never heard of and stick with big national brands. That bias can be expensive. The research is clear: brand recognition isn’t the same as a better rate or better service. An unfamiliar lender with strong reviews, transparent fees, and a licensed loan officer who answers the phone on the first ring may outperform a household name in every way that actually matters to you on closing day.
New families moving into a home also tend to underestimate the expenses that follow. Beyond the mortgage itself, there’s landscaping, security, and structural work, the kind of post-purchase improvements that smart buyers budget for ahead of time. The point is that thoughtful buyers plan for what comes after the loan closes, not just the loan itself.
Frequently Asked Questions
How many lenders should I contact when shopping for a mortgage?
Talk to at least three lenders before making a decision. Research from Freddie Mac shows that shopping multiple lenders can save a buyer more than $1,000 per year. Getting three Loan Estimates gives you a real basis for comparison, on rate, APR, fees, and closing costs, rather than taking the first offer you receive and hoping it’s fair.
Does getting pre-approved by multiple lenders hurt my credit score?
Not significantly. Credit bureaus recognize that mortgage rate shopping is normal behavior. Multiple hard inquiries from mortgage lenders within a 14 to 45 day window are typically grouped and counted as a single inquiry. The short-term impact is small. The savings from finding a better rate are almost always worth more than the minor score dip.
What’s the difference between interest rate and APR on a mortgage?
The interest rate is the base cost of borrowing. The APR, annual percentage rate, adds lender fees and other loan costs to that number and expresses the total as an annual percentage. APR is the more complete figure for comparing lenders. A loan with a lower interest rate but higher fees can cost more than a loan with a slightly higher rate and minimal fees. Always compare APR, not just rate.
Should I use a local lender or a national online lender?
Both can work well. Local lenders often have stronger knowledge of the regional market, faster communication, and personal accountability. National online lenders sometimes offer lower rates due to lower overhead. The better question is: how responsive are they, how transparent are they about fees, and do they have a real track record of closing on time? Those factors matter more than geography.
What should I do if a lender promises me the lowest rate available?
Be skeptical. No single lender has the lowest rate every day for every borrower. Rates shift constantly, and different lenders price loans differently based on their current business volume and risk appetite. A lender making that guarantee is making a claim they can’t actually verify. Get the quote in writing, compare it against two other Loan Estimates, and let the numbers speak for themselves.
When should I lock my mortgage rate?
Most lenders allow you to lock once you’re under contract on a home. Lock as soon as you’re comfortable with your lender choice and the rate is acceptable, don’t try to time the market. Rate locks typically last 30 to 60 days. Ask about the cost to extend before you lock, especially if your closing timeline has any uncertainty built in.
