Mortgage basics

A Mortgage Is a Loan Secured by Your Home.

For a Texas homebuyer, the practical work is understanding what you promise to repay, what the lender must review, and which documents describe estimated and final terms.

The loan and the property work together.

A home loan creates a debt and a claim against the property that secures it. The promissory note records the borrower's promise to repay according to the agreed terms. A deed of trust or other security instrument connects the debt to the property and describes the lender's rights.

The purchase contract, loan application, title review, appraisal, insurance, and closing documents each serve a different purpose. A lender reviews the complete transaction because approval depends on both the borrower and the property.

Application information begins the review.

A mortgage application brings together identity, employment, income, assets, debts, credit, property, occupancy, and transaction information. The lender may ask for documents that support or clarify the information provided.

An early conversation or initial review can help organize the next step, but it is not the same as final approval. Ask what information has been reviewed, what remains unverified, and which property-specific items are still outstanding.

The Loan Estimate organizes estimated terms and costs.

The Loan Estimate is a federal disclosure that presents important loan features, projected payments, and estimated closing costs based on the information available at that time. It helps a borrower review and compare the proposed transaction. It does not guarantee approval or lock every figure.

The Consumer Financial Protection Bureau explains the document in its official Loan Estimate guide.

Underwriting tests the file against requirements.

Underwriting reviews verified information under the rules that apply to the requested loan. The reviewer may identify conditions that must be satisfied before a final credit decision or closing. Conditions can relate to the borrower, source of funds, property, title, insurance, or transaction.

New information can change the review. Continue to answer requests accurately and ask before making a financial change that could affect the file.

The Closing Disclosure shows the final transaction details.

The Closing Disclosure presents final loan terms and closing costs for many consumer mortgage transactions. Compare it with the latest information you received, review changes, and ask about anything you do not understand before signing.

Mortgage basics FAQ

Four foundational answers.

What is a mortgage?

A mortgage is a loan used to buy or refinance real property, with the property serving as security for the debt. The note states the promise to repay, and the security instrument gives the lender rights in the property if the loan terms are not met.

Does a Loan Estimate mean the loan is approved?

No. A Loan Estimate presents estimated terms and costs based on information available at that stage. It is not a credit decision or commitment to lend.

What does underwriting review?

Underwriting reviews verified borrower, credit, income, asset, debt, property, occupancy, and transaction information under the requirements that apply to the requested loan.

Is a prequalification the same as final approval?

No. Early review labels and scope can vary, but final approval requires the lender to complete the applicable borrower, property, and underwriting review and to resolve required conditions.
