MUST KNOW

APR (Annual Percentage Rate)

The TRUE cost of your loan per year, including interest rate PLUS fees. Always higher than the interest rate alone.

Example: Compare APRs, not just interest rates, when shopping for mortgages.

Adjustable-Rate Mortgage (ARM)

A mortgage where the interest rate changes periodically. Starts with a lower rate for 3-10 years, then adjusts.

Example: A 5/1 ARM has a fixed rate for 5 years, then adjusts every 1 year.

Amortization

The process of paying off your loan over time. Early payments are mostly interest; later payments are mostly principal.

Example: On a 30-year mortgage, you won't pay more principal than interest until about year 18!

Appraisal

A professional assessment of a home's market value. Required by lenders to ensure the home is worth the loan amount.

Example: Cost: $300-$600, paid by the buyer.

Assumable Mortgage

A mortgage that can be transferred from seller to buyer, keeping the original rate. FHA, VA, and USDA loans are assumable.

Example: Assuming a 3% mortgage from 2021 can save you hundreds per month!

Balloon Mortgage

Low monthly payments for 5-7 years, then the entire remaining balance is due in one lump sum.

Example: Risky for most buyers. Only consider if you'll sell or refinance before the balloon payment.

Bridge Loan

A short-term loan to buy a new home before selling your current one. Uses your current home's equity.

Example: Typical terms: 6-12 months, 8-10% interest rates.

Buydown

Paying extra upfront to temporarily reduce your interest rate for the first few years.

Example: A 2-1 buydown on a 6% loan means you pay 4% year 1, 5% year 2, then 6% after.

Cash-Out Refinance

Refinancing for more than you owe and taking the difference in cash. Uses your home equity.

Example: Common uses: Home improvements, debt consolidation. Limited to 80% LTV.
MUST KNOW

Closing Costs

All fees paid when finalizing your mortgage: lender fees, title insurance, appraisal, attorney fees, prepaid taxes/insurance.

Example: Expect 2-5% of loan amount. On $400K loan = $8,000-$20,000.

Conforming Loan

A mortgage meeting Fannie Mae/Freddie Mac guidelines, including loan limits ($806,500 in 2026).

Example: Conforming loans typically have lower rates than jumbo loans.

Contingency

A condition in your purchase contract that must be met for the sale to proceed.

Example: Common contingencies: financing, inspection, appraisal.

Conventional Loan

A mortgage NOT backed by a government agency (FHA, VA, USDA). Requires higher credit scores.

Example: Usually 620+ credit, 3-20% down, PMI if less than 20% down.

Deed

The legal document that transfers property ownership from seller to buyer.

Example: Recorded with the county after closing.

Down Payment

The upfront cash you pay toward the home purchase. The rest is covered by your mortgage.

Example: Minimums: Conventional 3-5%, FHA 3.5%, VA 0%, USDA 0%.
MUST KNOW

DTI (Debt-to-Income Ratio)

Your total monthly debt payments divided by gross monthly income. Determines how much you can borrow.

Example: Most lenders want DTI below 43%. Formula: (All debts ÷ Gross income) × 100

Earnest Money

A deposit when your offer is accepted, showing you're serious. Held in escrow until closing.

Example: Typical: 1-3% of purchase price. Applied to your down payment.

Equity

The portion of your home you own—the difference between value and what you owe.

Example: Home worth $400K, mortgage $300K = $100K equity (25%).
MUST KNOW

Escrow

An account where your lender holds money for property taxes and insurance, paid monthly with your mortgage.

Example: Ensures your taxes and insurance are always paid on time.

FHA Loan

Government-backed mortgage insured by Federal Housing Administration. Popular with first-time buyers.

Example: 580+ credit for 3.5% down. Requires MIP (mortgage insurance).

Fixed-Rate Mortgage

A mortgage where the interest rate stays the same for the entire loan term.

Example: Predictable payments that never change (except tax/insurance adjustments).

Forbearance

A temporary pause or reduction in payments during financial hardship.

Example: Missed payments typically added to the end of the loan.

Gift Funds

Money given by family to help with your down payment. Requires a gift letter.

Example: FHA allows 100% gift. Conventional may require some of your own funds.

HELOC

Home Equity Line of Credit. A revolving credit line secured by your home equity.

Example: Works like a credit card—borrow as needed, pay interest only on what you use.

HOA

Homeowners Association. Manages community and collects fees for shared amenities.

Example: Fees range $100-$1,000+/month. Factor into your budget!

Jumbo Loan

A mortgage exceeding conforming loan limits ($806,500 in most areas for 2026).

Example: Usually 700+ credit, 10-20% down, lower DTI ratios required.

Lien

A legal claim against your property. Your mortgage is a lien.

Example: If you don't pay, the lender can foreclose.

Loan Estimate (LE)

A standardized form showing estimated rate, payment, and closing costs. Provided within 3 days of application.

Example: Compare Loan Estimates from multiple lenders to find the best deal.
MUST KNOW

LTV (Loan-to-Value Ratio)

Your loan amount divided by home value. Determines PMI requirements and affects your rate.

Example: $320K loan on $400K home = 80% LTV (no PMI required!)

Rate Lock

A guarantee your interest rate won't change for a set period (30-60 days) while you close.

Example: Lock when comfortable with the rate. Longer locks may cost more.

MIP (Mortgage Insurance Premium)

FHA's version of PMI. Includes upfront (1.75%) plus annual premiums (0.55%).

Example: FHA MIP lasts for life of loan. Conventional PMI can be removed at 20% equity.

Mortgage Broker

A middleman who shops multiple lenders on your behalf to find the best rate.

Example: Pros: Access to many lenders. Cons: Additional fees.

Negative Amortization

When your payment doesn't cover all interest due, and unpaid interest adds to your balance.

Example: Avoid! Your debt grows instead of shrinking.

Origination Fee

A fee charged by the lender for processing your loan. Typically 0.5%-1% of loan amount.

Example: Often negotiable, especially with strong credit.

PITI

Principal, Interest, Taxes, and Insurance—the four components of your total monthly payment.

Example: Always calculate PITI, not just P&I. Taxes/insurance can add $500+/month!
MUST KNOW

PMI (Private Mortgage Insurance)

Insurance required when down payment is less than 20%. Protects the LENDER if you default.

Example: Adds $100-$400/month. Can be removed at 20% equity.
MUST KNOW

Points (Discount Points)

Upfront fees to lower your rate. One point = 1% of loan, typically reduces rate by 0.25%.

Example: On $400K loan, 1 point costs $4,000, saves ~$60/month. Break-even: 5.5 years.
MUST KNOW

Pre-Approval

A lender's conditional commitment to lend based on verified income, credit, and assets.

Example: Much stronger than pre-qualification. Essential in competitive markets.

Prepayment Penalty

A fee charged if you pay off your mortgage early. Rare on standard mortgages today.

Example: Check your loan documents to be sure.

Principal

The amount you borrowed (or still owe), not including interest.

Example: Each payment reduces your principal balance.

Refinance

Replacing your current mortgage with a new one for a lower rate, different term, or cash out.

Example: Makes sense if you can lower rate by 0.75%+ and stay 3+ years.

Second Mortgage

An additional loan against your home while you still have your first mortgage.

Example: HELOCs and home equity loans are types of second mortgages.

Seller Concessions

When the seller agrees to pay some of your closing costs.

Example: FHA allows up to 6%, conventional 3-9% depending on down payment.

Streamline Refinance

Simplified refinance for FHA/VA/USDA with reduced documentation and no appraisal.

Example: Faster and cheaper than standard refinancing.

Title

Legal ownership of a property. A title search ensures no claims or liens before you buy.

Example: Title insurance protects against defects discovered after closing.
MUST KNOW

Underwriting

The process where a lender verifies your income, assets, credit, and property to approve your loan.

Example: Takes 1-3 weeks. Don't make major financial changes during this time!

USDA Loan

Government-backed mortgage for rural/suburban buyers with no down payment. Income limits apply.

Example: Many suburban areas qualify as "rural" for USDA purposes.

VA Loan

Mortgage guaranteed by VA for veterans and active-duty. No down payment or PMI required.

Example: 0% down, no PMI, competitive rates. One of the best programs available.
