What actually sets your mortgage rate and closing costs, and which parts you control

The short answer: your file, your loan choices and the market on the day you lock

Your mortgage rate is set by three things working together: the risk your file represents (mostly credit score and down payment), the choices you make about the loan (program, term, fixed or adjustable, and whether you pay points), and the market on the day you lock. Closing costs are a separate bill made up of lender charges plus third-party costs such as appraisal, title, prepaid interest, property taxes and homeowners insurance. You control more of both than most people think, but only if you know which levers to pull before you apply.

I have worked in mortgage lending for more than twenty-three years, and the question I hear most is some version of what is your rate. I never quote one in an article or on a first phone call, because a rate is specific to a person, a property, a program and a day. What I can do is explain exactly what moves it, so the number you eventually see on a Loan Estimate makes sense and you can tell whether it is fair.

Seven things a lender prices into your rate

The Consumer Financial Protection Bureau lists seven factors that determine a mortgage interest rate, and they match what I see in pricing every day. Some of these are fixed by the house you are buying. Others are decisions you can make, and a few are things you can improve in the months before you apply.

• Credit score: the CFPB notes that borrowers with higher scores generally receive lower rates
• Location: rates can differ by state and sometimes by county
• Home price and loan amount: particularly small or particularly large loans can carry higher rates
• Down payment: more equity generally means less risk to the lender and a lower rate
• Loan term: shorter terms usually carry lower rates and lower total interest, with higher monthly payments
• Rate type: fixed stays the same, while an adjustable rate may start lower and can change later
• Loan type: conventional, FHA, VA and USDA loans are each priced differently

The levers that belong to you

Credit is the biggest one. A score that sits just below a pricing threshold can cost real money over the life of a loan, and sometimes a few months of paying down card balances or correcting a reporting error moves it across the line. My team helps clients build credit when that is the obstacle, and I wrote a separate guide on what you can fix on your credit yourself before you apply.

Down payment is the second lever. A larger down payment can improve pricing and, on a conventional loan, affects whether you pay mortgage insurance. The CFPB notes that mortgage insurance is typically required when the down payment is under 20 percent of the price. That does not mean you need 20 percent to buy; it means you should understand what the smaller down payment costs you each month and decide with your eyes open.

The third lever is the loan itself. Program, term and rate type all change the price. A veteran may find a VA loan priced very differently from a conventional loan on the same house, and a buyer with newer credit may find FHA a better fit. If you are not sure which program to compare, start with my guide on FHA, conventional and VA loans side by side.

Points and lender credits: paying now or paying later

Every Loan Estimate shows a trade between upfront cost and rate. Discount points are money you pay at closing to lower your interest rate. Lender credits work the other way: the lender covers some closing costs in exchange for a higher rate. You can choose points, credits or neither, and the CFPB describes exactly this trade-off in its guidance on rates.

The right answer depends on how long you expect to keep the loan. If you plan to stay in the house and keep the mortgage for many years, buying the rate down can make sense. If you expect to move, sell or refinance in a few years, paying extra upfront may never pay back. I walk clients through the break-even on their real numbers, because the math is simple once someone lays it out and very confusing when nobody does.

Be careful with offers advertised as no closing costs. The CFPB explains that lenders usually do this one of two ways: a higher interest rate with a credit to cover costs, or rolling the costs into the loan amount. Neither is free. Each can be the right choice for some borrowers, but you should know which one you are getting.

Where closing costs come from

Closing costs are not one fee. They are a stack of charges from different parties, and only some of them come from the lender. The Loan Estimate separates them so you can see which ones you can shop for and which ones the lender chooses. Title charges are a big part of a Texas closing; a title company explains its side of the transaction well in this guide on what the title company does while you are under contract.

• Origination charges: what the lender charges to make the loan, including any points
• Appraisal and credit report: third-party services the lender orders
• Title insurance and settlement fees: charges from the title company
• Recording fees: what the county charges to record the deed and the mortgage
• Prepaid interest: interest from the closing day to the end of that month
• Escrow deposits: an initial cushion for property taxes and homeowners insurance
• Homeowners insurance premium: usually the first year, paid at or before closing

Costs that are not really the lender's to set

Some of the largest numbers on a closing statement have nothing to do with which lender you choose. Property taxes are set by local taxing units, and in the Dallas area they are a meaningful part of the monthly payment, so the escrow deposit at closing can look large. Homeowners insurance premiums are set by your insurer, not by us. The CFPB makes the same point on its Loan Estimate explainer: insurance and taxes are estimates the lender passes through.

That matters when you compare offers. A lender who shows a lower total cash to close may simply have estimated taxes or insurance lower than another lender, and the real bill will be the same. When I compare Loan Estimates with a client, I separate the lender's own charges from the pass-through items first. The lender's charges are where the real comparison lives.

How to compare two Loan Estimates without getting fooled

The Loan Estimate is a standard form, which is the best thing that ever happened to mortgage shopping. Ask for one from each lender you are considering, for the same loan program, the same term and the same lock period, ideally on the same day. Rates move daily, and an estimate from Monday cannot be compared fairly with one from Thursday.

Then look at the right lines. Compare the origination charges total. Compare the services you cannot shop for. Check whether the rate is locked or floating and for how long. Look at the APR and the total interest percentage in the comparisons section, which roll fees and interest into one figure. And ask each lender why any number differs from what you expected. If you want help with the questions that sit behind the numbers, my guide on what to ask a mortgage lender before you apply covers them.

Comparing is not a reason to delay. The CFPB notes that mortgage credit checks within a 45-day window are recorded as a single inquiry, so shopping several lenders inside that window does not multiply the effect on your score.

Mistakes that quietly raise what you pay

The most expensive mistake is shopping on an advertised rate. Advertised rates usually assume excellent credit, a large down payment and points paid at closing. The second is comparing a locked quote with an unlocked one. The third is taking on new debt while the loan is in process, which can change your pricing or your approval right before closing.

Others are smaller but common. Buyers sometimes pay off a collection without asking whether it will help the score, or close old credit cards to tidy up and end up lowering their available credit. Some assume their first-time buyer status automatically qualifies them for assistance without checking the program rules. And many never ask about the break-even on points, which is the one calculation that tells you whether paying more today makes sense.

What a cost conversation with me looks like

When someone calls my team at First United Bank in Preston Center, we start with the picture, not the rate: price range, down payment, credit, income and how long you expect to keep the home. From there we can show which programs fit, what each would cost upfront and monthly, and where points or credits make sense. If you are a first-time buyer, my earlier guide on whether you qualify and how to get from unsure to closed is a good place to start.

Because processing, underwriting, closing and funding all sit in-house, and we do not add our own overlays to Fannie Mae and Freddie Mac guidelines, the numbers we discuss are built on the real guidelines rather than a stricter internal version. A formal Loan Estimate comes after an application. Nothing in this article is a rate quote or an approval promise; your actual pricing depends on your file and the market the day you lock, and a licensed loan officer should walk you through it.
