Principal
The amount you borrowed. Early payments are mostly interest; later payments retire more principal.
How a mortgage works
A mortgage is a loan secured by the home. You make monthly payments of principal and interest (often plus taxes and insurance in escrow). Miss payments long enough and the lender can foreclose.
Interest rate
What you pay for the loan. Credit, down payment, loan type, and market rates all matter.
Term
Usually 15 or 30 years. Shorter terms cost less interest but raise the monthly payment.
Equity
Home value minus what you still owe. Built by payments and (sometimes) rising prices.

Common mortgage types
Conventional
Not government-backed. Often needs stronger credit. PMI may apply with under 20% down.
FHA
Lower down-payment path with mortgage insurance. Helpful for first-time buyers; know the ongoing costs.
VA / USDA
Special programs for eligible veterans or certain rural buyers — often competitive terms when you qualify.
Fixed vs. ARM
Fixed rates stay put. Adjustable-rate mortgages can start lower, then change — great or risky depending on your timeline.
When a mortgage is a good decision
Often smart when…
- You’ll likely stay 5+ years (to absorb closing costs)
- Payment fits a written budget with room to spare
- You have emergency savings after the down payment
- The home’s total cost beats renting in your market over time
- Job / income outlook is reasonably stable
Often not smart when…
- You’re stretching for the maximum approval amount
- You need to move in 1–2 years
- Buying would wipe out your cash reserves
- Maintenance, HOA, or repairs aren’t in the plan
- You’re buying mainly from social pressure or FOMO
Leverage cuts both ways
A mortgage can build wealth if you can sustain the payment and keep the home. It can also amplify stress if income drops, rates reset, or repairs pile up. “Approved” is not the same as “affordable.”
Getting a loan: pre-approval, rate locks & points
These steps happen between “I want a house” and closing. Knowing the difference helps you shop lenders without surprises.
Pre-qualification vs. pre-approval
Pre-qualification is a rough estimate based on what you tell a lender — quick, but not verified. Pre-approval involves document review (income, assets, credit pull) and carries more weight with sellers. Get pre-approved before serious shopping so you know your real budget.
Rate lock basics
A rate lock holds your quoted interest rate for a set period (often 30–60 days) while you close. If rates rise, you’re protected; if they fall, you may not get the lower rate unless your lock includes a float-down option. Ask how long the lock lasts and what happens if closing delays.
Points vs. rate tradeoff
Discount points are upfront fees that buy a lower rate — each point is typically 1% of the loan amount. Paying points can make sense if you’ll keep the loan long enough for the monthly savings to exceed the upfront cost. Run both scenarios in our mortgage calculator before deciding.
Compare Loan Estimates
Lenders must give you a Loan Estimate within three business days of application. Compare the same loan type, term, and rate-lock period across at least two or three lenders — not just the rate on a billboard.
Questions before you commit
Ask each lender: What’s my all-in monthly payment including taxes and insurance? What’s the rate lock period? Are there prepayment penalties? Can I talk through the numbers with someone who isn’t selling the loan?
Costs beyond the sticker price
-
1
Closing costs
Origination, appraisal, title, prepaid taxes/insurance — often thousands upfront.
-
2
Property tax & insurance
These can rival the principal & interest in some areas. Model them explicitly.
-
3
Maintenance & HOA
Budget a percentage of home value annually for upkeep — plus any association fees.
-
4
Opportunity cost
Money in a down payment isn’t invested elsewhere. Run both paths honestly.
