Buying a home means comparing mortgage lenders as carefully as you compare homes. This list is designed to help you ask better questions before preapproval, before you apply, or before you lock a rate so you can evaluate loan options, fees, communication, and how reliably each lender executes.
Whether you already have a home in mind or you want to get preapproved first, use these 12 questions to compare mortgage companies and choose the lender that best fits your situation.
Not all lenders are the same, and you may see meaningful differences in the categories above depending on the company, loan options, pricing approach, and service model.
For example, one lender may emphasize speed and self-service tools, while another may offer more hands-on guidance. The goal is to find a lender that provides competitive rates and fees, explains your options clearly, and can execute the process smoothly from preapproval through closing.
When you buy a home, having the right mortgage for your finances and future plans is critical. Before you settle on a mortgage company, make sure you understand how that lender will advise you, what the loan will cost, and what kind of support you can expect during the process.
As you ask the questions below, compare each lender’s answers across four areas:
A strong lender answer should be specific, easy to understand, and tailored to your situation rather than generic or overly sales-focused.
Here are the dozen top questions you need to have answered before having a mortgage company start the loan application or preapproval process.
This matters because you need to understand your full set of options instead of being steered toward a single loan program. The right mortgage depends on your financial goals, how long you expect to keep the loan, and what tradeoffs you are comfortable making.
A strong lender answer should include multiple relevant options, explain the pros and cons of each, and help you compare them in a way that informs rather than pressures you. Your mortgage lender should be able to advise you on which option makes the most sense based on your specific situation.
This matters because the right down payment is not always 20%. Your down payment affects your monthly payment, available reserves, loan options, and whether mortgage insurance may be required.
While most mortgage lenders will tell you that 20% is the ideal amount for a mortgage down payment, the truth is that you can get a home loan with just 10%, 3.5%, or even 0% down. It all depends on what kind of loan programs you qualify for. Make sure you tell potential lenders if you are a military veteran or if you’re a first-time home buyer, as you might qualify for federally backed loan programs like a VA or FHA loan.
Not every homebuyer should put 20% down. If a borrower doesn’t have substantial reserves built up for an emergency fund or they have a big expense coming up (like needing to enroll their kids in college), a large down payment may not make sense. On the other hand, a borrower living on a fixed income that isn’t likely to increase in the coming years may want to put more than 20% down to reduce their monthly payment.
A strong lender answer should show how different down payment options affect your payment, cash reserves, and loan structure.
This matters because rate quotes are only useful if you understand the assumptions behind them. Your rate can depend on factors such as credit, loan type, down payment, and whether discount points are included.
Your mortgage interest rate should be specific to you and something that your lender can answer confidently. Remember that your interest rate is based on assumptions about things like credit scores. If you have less than perfect credit, a bump in interest might still make you a good enough risk to lend money to.
Discount points should never be factored into the base interest rate. If you see rates with discount points, those should be presented in comparison to rates without points. Your Loan Officer should be able to inform you as to how long it will take to benefit from paying points and which option is best for you based on the timeframe you expect to keep the loan.
A strong lender answer should clearly separate the rate from the cost to get that rate and explain the tradeoff between paying points and keeping upfront costs lower.
This matters because timing affects both your shopping process and your expectations. You want to know when a hard credit pull is required and when a lender can give you preliminary information without one.
A “hard” credit check can slightly impact your credit score. Multiple checks can have an even more significant effect. To dampen down the damage done, get all of your checks by different potential lenders done over a short time period, like two weeks, so the credit bureaus know you’re just house shopping, not scrabbling to open up a bunch of credit lines.
A hard-pull credit check will be required for loan preapproval or if you’re ready to move forward with the loan process; however, it should not be required if you’re just inquiring about current rates and costs. A transparent lender will provide you with rate and cost information making assumptions on your credit. Obviously if your actual score ends up being lower than the score you gave the lender to get the quote, the terms will change.
A strong lender answer should explain when the credit pull happens, why it is needed, and what kind of quote information can be provided before that step.
This matters because a rate lock can affect both your costs and your peace of mind. You should understand whether the lock has a charge, how long it lasts, and what happens if market rates change.
Ideally, the answer to this question is that the lender clearly explains your lock options and any associated cost. An interest lock effectively freezes your quoted interest rate for a specific period of time, usually at least 30 days. Some mortgage companies guarantee it won’t change, period. Others do one better and don’t let increases affect the locked rate, but do let drops in rate benefit you.
A strong lender answer should outline the lock period, any fee, and whether there is any flexibility if rates improve after you lock.
This matters because PMI can change the total cost of your monthly housing payment and may influence which loan structure makes the most sense.
If you have less than the traditional 20% down payment, and are buying a home with a program that allows a lower down payment, you’ll likely have to pay for private mortgage insurance (PMI). This is an extra amount you pay every month on top of your mortgage payment.
If you do have to pay PMI, ask about the possibility of discontinuing the insurance once your home builds equity and you’ve paid off a chunk of your mortgage. In many cases you can negotiate the cessation of PMI once a specific milestone is reached, or refinance to get away from the requirement.
Depending on the mortgage market at the time you’re buying a home there are also other PMI options that can potentially save you money and worth considering. Two primary options are Lender Paid PMI and Upfront PMI.
Which option is the best depends on your specific situation and the PMI premiums at the time you are looking to lock your rate. A quality Loan Officer can review your options and advise you on the best option when you’re ready to lock.
A strong lender answer should explain whether PMI applies, what your alternatives are, and how each option affects your monthly payment and upfront costs.
This matters because your plans can change. If you sell, refinance, or pay off the loan early, you want to know whether doing so would trigger an added cost.
If you come into some cash, need to move and sell your home, or end up paying off your home early for any other reason, remember that lenders make their money on the interest they charge for your loan, which is earned over time. Make sure that if you pay your loan early, you don’t have a prepayment penalty clause that means you have to pay those years of interest.
A strong lender answer should state clearly whether a prepayment penalty exists and when it could apply.
This matters because total loan cost is broader than the interest rate alone. You need to understand lender fees, third-party fees, and how pricing choices affect what you bring to closing.
Ask about lenders fees and closing costs. These are separate, and your mortgage lender will know what you’re talking about. They should disclose any loan origination fee as something you’ll have to pay the mortgage lender directly.
Closing costs will include fees from third parties, such as your appraisal, title search, and property taxes. Your closing costs will be tied to the rate you choose. If you choose a rate with discount points the costs will obviously be higher than a rate without points.
You can even choose a higher rate in exchange for the lender providing a credit to cover part or all of your closing costs. Which option is best for you depends on how long you plan on keeping the loan.
A strong lender answer should separate lender fees from closing costs and explain the cost tradeoffs behind different rate options.
This matters because the document process can either slow things down or keep your loan moving. Ease of submission and visibility into what is still needed can make a big difference.
The ability to upload copies of your documents into a digital interface can make the application process much easier than if you have to depend on mail and fax. Find out if you have to sign in person as well – your lender might offer an e-closing option.
A good lender will have an online portal linked to their online application which makes uploading documents easy and also allows you to see what needs to be provided in one clean interface.
A strong lender answer should explain how documents are uploaded, how secure the process is, and how you will know what is outstanding.
This matters because communication quality often depends on who owns each part of the process and what backup is available when your main contact is unavailable.
In the old days the norm was to have a Loan Officer that worked with you from beginning to end. The downside to this model is that things would fall apart if the Loan Officer was unavailable, sick or on vacation. Additionally as lending has become more and more complex, different parts of the process require different skill sets.
Find out who you’ll be working with and what happens if that person is unavailable. Ideally the lender you work with will have a team model that allows for another Loan Officer or Loan Processor to assist and take over while your main contact is unavailable.
This is extremely important during the house hunting process when you’re making offers on homes. No single Loan Officer can always be available, so having a team on-call is vital to make sure you can get assistance when necessary even on weekends.
A strong lender answer should identify your main point of contact, explain who else supports the file, and tell you what happens if timing becomes urgent.
This matters because your contract timeline, move plans, and rate-lock decisions all depend on a realistic closing estimate.
Your closing date should be somewhat predictable, and your lender shouldn’t hesitate to give you at least a date range for when you can expect to close. Ask what sort of guarantee, if any, they provide for closing. A guarantee without monetary compensation if the dates aren’t hit doesn’t really mean much. Please note that some states prohibit a lender from making any guarantees that they can close on a specific date.
A strong lender answer should give a realistic timeline, explain what could affect it, and set expectations clearly rather than overpromising.
This matters because the best comparison happens when you ask the same core questions in a consistent way and review the answers side by side before moving forward.
Once you have answers, compare each lender on loan fit, pricing transparency, communication, and closing reliability. If one lender offers a lower rate, make sure you also understand whether points, lender fees, PMI structure, or process limitations are part of that quote.
A strong lender answer should make it easy for you to understand your next step, whether that means getting preapproved, reviewing a formal loan estimate later in the process, or narrowing your choices to the lender that best matches your priorities.

The most important questions help you compare loan fit, pricing transparency, communication, and closing reliability. Ask about loan options, down payment choices, your interest rate and whether points are included, when a hard credit check happens, rate-lock terms, PMI, prepayment penalties, lender fees and closing costs, document submission, who will handle your file, and how long closing may take.
Before preapproval, ask which loan programs fit your situation, how much down payment makes sense, when the lender will run a hard credit check, what assumptions are behind the quoted rate, what documents are needed, who you will work with, and how quickly the lender can issue the preapproval and close if you go under contract.
A hard credit check can slightly affect your credit score. Shopping with several lenders over a short period may limit the impact because the credit bureaus can recognize that you are rate shopping rather than opening multiple unrelated credit lines.
The right down payment depends on your goals, cash reserves, payment comfort, and loan options. It is not always 20 percent. Some borrowers may qualify for lower down payment programs, including FHA or VA options, while others may choose to put more down to reduce their monthly payment.
Lender fees are charges paid directly to the mortgage company, such as origination-related fees. Closing costs also include third-party charges like appraisal, title, and property-tax-related costs. A clear lender should separate these categories and explain how your rate choice and any discount points affect the total.
Yes. Rate-lock details matter because they affect both cost and timing. Ask whether there is a charge, how long the lock lasts, and whether the lender offers any flexibility if rates improve after you lock.
If you make less than a 20 percent down payment on a conventional loan, PMI may apply. A lender should explain whether PMI is required, how much it may add to your monthly payment, whether lender-paid or upfront PMI options are available, and when PMI might be removed later.
Not every mortgage has a prepayment penalty, so it is important to ask directly. If one applies, the lender should explain exactly when it could be triggered, such as if you sell, refinance, or pay off the loan early.
Getting preapproved before house hunting can help you understand your budget and move faster when you are ready to make an offer. It also gives you a chance to compare lenders on pricing, process, and communication before you are under contract.
Compare enough lenders to evaluate differences in loan options, rates, points, lender fees, communication, and closing timelines. The goal is not just to find the lowest quoted rate, but to identify the lender that gives clear answers, offers a loan structure that fits your situation, and can execute reliably through closing.
