Buying a home in Dallas, Richardson, Plano, Allen, Frisco, and across Collin County comes with a whole new language, especially when it comes to mortgages. Understanding these key mortgage terms can help you feel confident, avoid surprises, and make smarter financial decisions throughout your homebuying journey.
Here’s a simple, easy-to-follow high level look at the most important mortgage terms every buyer should know:
✅ Loan Qualification & Approval Terms
-
Pre-Qualification
A quick lender estimate based on what you report: no documents verified yet. -
Pre-Approval
A stronger step where the lender verifies your credit, income, and assets to determine what you truly qualify for. -
Loan Commitment
Formal written approval from the lender stating the buyer meets all conditions for the loan. -
Clear to Close (CTC)
Final approval confirming the loan is ready for closing.
💰 Down Payments & Mortgage Insurance
-
Private Mortgage Insurance (PMI)
Required on conventional loans with less than 20% down. Can be removed once 20% equity is reached. -
Mortgage Insurance Premium (MIP)
Required on FHA loans. Usually stays for the life of the loan unless 10%+ is put down. -
Down Payment Assistance (DPA)
State and local programs that help qualified buyers with down payment and closing costs.
📊 Key Loan Metrics Buyers Should Know
-
Debt-to-Income Ratio (DTI)
Percentage of your gross monthly income that goes toward debt. Lower = better loan options. -
Loan-to-Value Ratio (LTV)
The percentage of the home price being financed. Higher LTV means higher lender risk.
📈 Interest Rate vs. APR (Important Difference!)
-
Interest Rate
The cost of borrowing money. -
Annual Percentage Rate (APR)
The true cost of the loan including interest + lender fees + closing costs.
🧾 Lender Fees to Expect

Origination Fee
Lender processing fee (usually 0.5%–1% of the loan). -
Discount Points

USDA Loan
Zero-down option for qualifying rural/suburban buyers (income limits apply). -

Loan that exceeds conforming loan limits (over ~$806,500 in most areas for 2025). -
Non-QM Loan (Non-Qualified Mortgage)
Flexible option for self-employed buyers, high-DTI borrowers, or bank-statement loans.
🧮 Mortgage Payment Breakdown (PITI)
Your total monthly payment includes:
-
Principal – Amount going toward your loan balance
-
Interest – Cost of borrowing
-
Taxes – Property taxes (collected through escrow)
-
Insurance – Homeowners insurance + PMI/MIP if required
🏦 Escrow & Reserves
-
Escrow Account
Lender-managed account for taxes & insurance payments. -
Reserves
Extra savings required by some lenders, usually 2–6 months of mortgage payments after closing.
🔄 Fixed vs. Adjustable Rate Loans
-
Fixed-Rate Mortgage
Same interest rate for the full loan term (15, 20, or 30 years). -
Adjustable-Rate Mortgage (ARM)
Starts with a lower fixed rate, then adjusts based on the market after the initial period.
💸 Rate Buy-Down Options
-
Temporary Buy-Down
Lowers your rate for the first 1–3 years (like a 2-1 buy-down). -
Permanent Buy-Down
Pay discount points upfront to lower your rate for the life of the loan.
