Credit
How you have managed borrowed money and monthly obligations over time.
Mortgage 103 | Course 3 of 6
Learn how the major financial pieces of your mortgage application work together, what lenders may need to verify and why seemingly small financial changes can affect your approval.
Start With the Full Picture
A lender reviews how your credit, qualifying income, available assets and monthly obligations work together. A strength in one area may help your overall application, but it does not automatically erase a concern in another.
The exact calculation and documentation requirements depend on the loan program, lender, borrower and property involved.
The Building Blocks
Each part answers a different question about your ability to qualify for and repay the proposed mortgage.
How you have managed borrowed money and monthly obligations over time.
The stable, verifiable income that may be used to calculate your ability to repay the loan.
The documented funds available for closing, reserves and other transaction requirements.
The recurring obligations that must be paid along with the proposed housing payment.
More Than a Score
Your credit report and credit score are related, but they are not the same thing. A score summarizes certain information from a credit report, while the report shows the underlying account and payment history.
Mortgage credit reports may include information from the three nationwide credit reporting companies.
The score matters, but it is only one piece of the credit review.
Different scoring models, credit-report data and calculation dates can produce different scores. A score provided by a bank, credit card company or monitoring application may not match the mortgage-related score obtained by a lender.
Income That Can Be Documented
The amount deposited into your bank account is not automatically the amount used for mortgage qualification. A lender must determine which income can be documented and calculated under the selected program.
The income must generally be supported by acceptable records such as pay statements, tax documents, account statements or third-party verification.
The history, source and pattern of the income may be reviewed to determine a reasonable qualifying amount.
Income generally must be reasonably expected to remain available for the period required by the applicable loan guidelines.
Variable income may need to be averaged. Business income may be calculated after eligible expenses. Newly started, declining, temporary or insufficiently documented income may be treated differently under the applicable guidelines.
Documented Money for the Transaction
Lenders may review your accounts to confirm that you have enough eligible funds for the transaction and to document where those funds came from.
Funds needed for the down payment, closing costs, prepaid expenses and other required amounts.
Additional eligible funds that remain available after closing when reserves are required.
Assets may also provide additional context about the overall financial profile, depending on the program.
Large deposits, cash deposits, newly opened accounts and transfers between accounts may require additional documentation. Keep statements, transfer records, deposit receipts and evidence showing the original source of the funds.
Comparing Income With Obligations
Your debt-to-income ratio, usually called DTI, compares applicable monthly debt payments with your qualifying gross monthly income.
Acceptable ratios vary by loan program, automated underwriting findings, credit profile, assets, property and lender requirements. A ratio that works for one borrower or program may not work for another.
Be Prepared to Verify the Details
Your exact list will depend on how you earn income, where your funds are held and which loan program you use.
Additional or updated documents may be requested throughout the process. An updated request does not necessarily mean there is a problem; lenders must verify that the information remains accurate before closing.
Keep Your Loan Officer Informed
Credit, income, assets and debts may be reviewed again before closing. Ask before making a major financial change.
A new account may add a monthly obligation, change your credit profile or require additional documentation.
Higher credit card or loan balances may change minimum payments, available funds and credit scores.
A new job, reduced hours or a change in pay structure may affect how qualifying income is calculated.
Transfers and deposits can create additional sourcing requirements if the transaction cannot be clearly followed.
A newly co-signed obligation may be treated as your debt even when another person plans to make the payment.
Closing a credit or bank account can affect available credit, credit history or documented funds.
Alabama Homebuyer Note
A preapproval may begin with an estimated housing payment. Once you select an Alabama property, the projected payment must be updated using information related to that specific home and location.
Common Questions
Not necessarily. The credit score used for loan qualification and pricing depends on the program and applicable lender guidelines. Adding a borrower does not automatically mean only the highest score controls the transaction.
No. The income must be eligible and documentable, and the lender must also evaluate credit, debts, assets, the property and all other applicable requirements.
It may be usable when the history, documentation and expected continuation satisfy the applicable program. The amount used may be based on an average rather than the most recent payment.
Gross business receipts are not the same as qualifying personal income. Applicable expenses, ownership, tax returns and other financial records may be considered when calculating usable income.
Mortgage programs generally require funds used for closing to come from an eligible, verifiable source. Undocumented cash can be difficult or impossible to use. Discuss the situation before depositing it into an account.
Not always. The payment, remaining term, source of payoff funds, credit effect and applicable program rules must be reviewed. Paying off a debt can also reduce the funds available for closing or reserves.
Many programs permit eligible gift funds, but the acceptable donor, required borrower contribution, documentation and transfer process vary. The gift must comply with the selected program.
Yes. The mortgage application requires complete and accurate information. Certain obligations may need to be considered even when they do not appear on the credit report.
