Mortgage terms in plain English
Six documents and concepts that can change how you compare a loan, read a Texas purchase contract, and plan cash for closing and homeownership.
Mortgage language becomes useful when each term is tied to a document, a decision, and the party responsible for it. This learning center explains six commonly confused concepts using current federal, Texas, and agency sources. Each guide tells you what the term means, where it appears, what it does not mean, and which document controls your transaction.
Key facts
- Loan Estimate: The early three-page mortgage disclosure used to compare proposed terms and estimated costs.
- Closing Disclosure: The final five-page mortgage disclosure used to review loan terms, costs, and cash to close before consummation.
- Earnest money: Contract funds delivered to the escrow agent under the timing and remedies written into the Texas purchase contract.
- Escrow account: A mortgage-servicing account used to collect and pay specified property expenses such as taxes and insurance.
- Seller concessions: Seller-funded amounts applied to allowable buyer costs, subject to the contract and applicable loan-program rules.
- PMI: Private mortgage insurance on certain conventional loans; it protects the lender rather than the borrower.
Start with the document, not the shorthand
Mortgage conversations compress several different ideas into phrases such as "closing costs," "escrow," or "seller credit." The same word can refer to a contract deposit, a settlement service, an account managed after closing, or a line on a federal disclosure. The reliable way to sort it out is to identify the controlling document first.
The Loan Estimate and Closing Disclosure are federal mortgage disclosures. Earnest money and the option fee are purchase-contract terms, and the current Texas resale form is published by the Texas Real Estate Commission. Escrow and PMI can continue after closing and are governed by the loan, servicing rules, and applicable law.
Use each guide for one decision
The pages below deliberately do not collapse into one giant homebuying article. Use the Loan Estimate guide when comparing proposed loans. Use the Closing Disclosure guide when checking final terms. Use the earnest-money guide for contract-fund questions. Use the escrow guide for tax-and-insurance collection, the seller-concessions guide for negotiated cost credits, and the PMI guide for conventional mortgage-insurance basics.
For numerical planning, move from definitions to the Texas closing cost calculator. For allocation questions, use who pays closing costs in Texas. Those pages own different questions and should not be treated as substitutes for the actual contract or disclosures.
What these definitions cannot decide
General definitions cannot determine whether a particular fee is accurate, whether contract funds are refundable, whether a seller contribution is permitted, or whether mortgage insurance can be cancelled. Those answers depend on the executed contract, loan type, occupancy, loan-to-value ratio, investor or agency rules, property, dates, and account history.
Use the guides to form better questions. For a live transaction, the signed contract, current disclosures, title or escrow records, lender instructions, and servicer records control. Contract interpretation and legal rights should be reviewed with the appropriate real-estate professional or attorney.

Questions about the learning center
Is this a complete mortgage glossary?
No. It is a focused set of high-impact terms that borrowers commonly encounter while comparing a loan, signing a Texas purchase contract, preparing to close, or reviewing a monthly mortgage payment.
Which document should I compare first when shopping for a mortgage?
Use official Loan Estimates issued for the same loan scenario and as close to the same time as practical. Compare loan terms, rate-lock status, origination charges, lender credits, projected payments, and cash to close rather than comparing a disclosure with an informal worksheet.
Do these definitions override my contract or loan documents?
No. These pages are general education. The executed contract, Loan Estimate, Closing Disclosure, note, security instrument, mortgage-insurance disclosures, and servicer records govern the transaction or account.
Where should I start if a number changed?
Compare the newest document with the prior version, identify the exact line that changed, and ask the responsible party for the reason. A contract amount, lender charge, third-party fee, prepaid item, escrow estimate, and seller credit can change for different reasons.
