Rates, Payments and Closing Costs
Learn what affects a mortgage interest rate, how your complete monthly payment is calculated and how closing costs differ from the total cash you may need to bring to closing.
Start With the Complete Cost
A mortgage costs more than the advertised interest rate.
The rate affects your principal-and-interest payment, but it does not show every cost connected with obtaining and maintaining the loan.
To compare options accurately, review the interest rate, APR, points, lender credits, complete monthly payment, closing costs and total cash needed for the transaction.
The Big Picture
Four costs to compare
Looking at only one number can make one option appear cheaper even when its total cost is higher.
2
Monthly payment
The complete recurring housing expense—not only principal and interest.
3
Closing costs
Loan charges, third-party services, prepaid items, escrow deposits and government fees.
4
Cash to close
The final amount due after the down payment, costs, deposits, credits and adjustments are combined.
The Cost of Borrowing
Interest rates, points and lender credits
Mortgage rates can change with market conditions, and the rate available to one borrower may differ from the rate available to another.
What may affect your rate
- Credit profile and qualifying credit score
- Loan type, loan term and repayment structure
- Down payment, equity and loan-to-value ratio
- Primary residence, second home or investment occupancy
- Property type and number of units
- Discount points or lender credits selected
- Current financial-market conditions
Points and lender credits
Discount points generally mean paying more at closing in exchange for a lower interest rate.
A lender credit generally reduces the amount paid toward eligible closing costs but may be connected with a higher interest rate than an option without that credit.
Neither option is automatically better. The comparison depends partly on how long you expect to keep the mortgage.

Paying points should be a break-even decision.
Compare the upfront cost with the monthly payment savings. Dividing the additional upfront cost by the estimated monthly savings can help show approximately how long it may take to recover the cost.
Two Different Percentages
Interest rate vs. APR
Both are expressed as percentages, but they measure different parts of the financing.
Interest rate
The interest rate is the percentage charged for borrowing the principal balance.
For a standard fixed-rate mortgage, the rate is used to calculate the scheduled monthly principal-and-interest payment.
Annual percentage rate
APR is a broader measure that reflects the interest rate and certain additional costs of obtaining the loan, such as applicable points and finance charges.
APR is useful when comparing similar loans, but it does not replace reviewing the actual payment, upfront costs and loan structure.
A lower rate does not automatically mean a lower-cost
loan.
One option may advertise a lower interest rate but require substantially more money in points or other upfront costs. Compare Loan Estimates using the same loan amount, down payment, term and lock period.
Protecting the Quoted Rate
What is a mortgage rate lock?
A rate lock generally protects the agreed interest rate for a specified period while the loan is being processed, provided the transaction closes within that period and material information does not change.
Before locking
Confirm the rate, points, lender credits, lock expiration date and whether any lock fee applies.
During the lock
Respond quickly to requests and notify your loan officer about changes to the property, application or closing schedule.
If the lock expires
An extension may be available, but it can involve a fee, different pricing or other conditions.
Rates can move before they are locked.
A rate discussed during an early conversation is not necessarily reserved. Ask for written confirmation when a rate is locked and review the expiration date.
More Than Principal and Interest
What makes up a monthly housing payment?
The principal-and-interest figure shown in an online calculator may be substantially lower than the complete amount used for qualification and budgeting.
P
Principal
The portion of the scheduled payment that reduces the outstanding loan balance.
I
Interest
The portion charged for borrowing the remaining principal balance.
T
Property taxes
The estimated local real-property taxes attributable to the selected home.
I
Homeowners insurance
The premium for the homeowners insurance policy required for the property.
MI
Mortgage insurance or annual fee
An additional cost that may apply based on the loan program, down payment and financing level.
+
Other property expenses
Flood insurance, homeowners association dues or other recurring property charges may also apply.
A fixed interest rate does not always mean the total
payment stays exactly the same.
Principal and interest may remain fixed, while property taxes, homeowners insurance, flood insurance and escrow requirements can change over time.
Paying Property Expenses Monthly
How an escrow account works
A mortgage escrow account allows a lender or loan servicer to collect part of certain property expenses with each monthly payment and pay the bills when they become due.

Escrow commonly covers taxes and insurance.
A portion of the monthly payment may be deposited into escrow for property taxes, homeowners insurance and certain other required property expenses.
The initial escrow payment collected at closing helps establish the account. The account may be reviewed periodically, and the monthly amount may increase or decrease when the underlying bills change.
Costs Connected With the Transaction
What are mortgage closing costs?
Closing costs can include charges from the lender, settlement or title provider, appraiser, government offices, insurance companies and other third parties.
Loan and Service Costs
- Lender origination or underwriting charges
- Discount points when selected
- Appraisal and credit-report charges
- Flood determination, tax or verification services
- Title search, title insurance and settlement services
- Other services required for the selected loan and property
Other Costs and Prepaids
- Recording and applicable government charges
- Prepaid interest through the end of the closing month
- Homeowners or flood insurance premiums
- Initial property-tax and insurance escrow deposits
- Homeowners association or transfer-related charges when applicable
- Other transaction-specific adjustments
“No closing costs” does not always mean the costs
disappeared.
Costs may be covered through a lender credit, seller contribution, assistance program, increased loan amount when permitted or another transaction structure. Review how the costs are being paid and whether that choice affects your rate, price, payment or long-term expense.
The Final Amount Due
Closing costs are not the same as cash to close
Cash to close combines multiple parts of the transaction. It can change as the final loan, property, insurance, title and contract figures are completed.

Loan Estimate
The Loan Estimate shows the estimated loan terms, projected payment, closing costs and cash to close based on the information available when it is issued.
Use it to review the proposed structure and compare similar options.
Closing Disclosure
The Closing Disclosure shows the final loan terms and transaction figures and should be compared with the most recent Loan Estimate.
For covered transactions, it is generally provided at least three business days before the scheduled closing.
Estimated costs can change before closing.
Some costs have legal limits on how much they may increase without a valid reason, while others can change with the property, services selected, insurance, rate lock or changed transaction information. Ask for an explanation when a figure changes.
Alabama Homebuyer Note
Alabama property costs can vary by home and location
Early estimates may use general property-tax and insurance assumptions. Once a specific Alabama property is selected, those estimates should be updated using information associated with that home and location.
- Alabama real-property taxes are administered locally and can vary by county, municipality, assessed value and applicable exemptions.
- Eligible owner-occupants may be able to claim an Alabama homestead exemption through the appropriate local county office after meeting the requirements.
- The seller's current property-tax bill may not be identical to the amount applicable to the buyer after the sale.
- Homeowners insurance pricing can change based on location, construction, roof, property condition, coverage and insurer requirements.
- A flood determination is used to identify whether flood insurance is required under the applicable financing rules.
- Taxes, prepaid expenses and other property costs may be prorated or adjusted through the Alabama closing statement.
- Homeowners association dues, assessments and transfer charges should be confirmed for the specific property.
- Updated taxes or insurance can affect both the monthly payment and final cash to close.
Common Questions
Rate, payment and closing-cost FAQs
Can my rate change after I am preapproved?
Yes. A preapproval does not necessarily lock an interest rate. Market rates may change until a rate is locked, and changes to the application or transaction may also affect available pricing.
Is the lowest advertised rate always the best option?
No. The advertised rate may assume a particular credit score, down payment, property, loan type or amount of discount points. Compare the APR, upfront costs, monthly payment and lock terms.
Can my monthly payment change on a fixed-rate mortgage?
The scheduled principal-and-interest payment generally remains fixed, but taxes, homeowners insurance, flood insurance, mortgage insurance or escrow amounts may change.
Are homeowners association dues included in my mortgage payment?
They are commonly paid separately to the association, although they may still be included when the lender calculates your qualifying housing expense.
Can the seller pay all of my closing costs?
Seller contributions may be permitted, but the maximum amount and eligible uses depend on the loan program, occupancy, down payment and transaction. A seller credit generally cannot simply become unrestricted cash back to the buyer.
Does earnest money reduce my cash to close?
Properly documented earnest money that is credited to the buyer at closing can reduce the remaining amount due, subject to verification and the final transaction figures.
Why did my cash to close change?
Changes can result from the final down payment, rate lock, lender credits, seller credits, insurance, title work, taxes, escrow deposits, prepaid interest, earnest money or other closing adjustments.
Should I wire funds using instructions received by email?
Do not rely only on an email. Verify wiring instructions directly with the closing office using a trusted phone number obtained independently. Fraudulent last-minute wiring changes are a serious risk.
