Home Mortgage
A home mortgage is a loan from a bank, mortgage company, or other lender to buy a residence. The property serves as collateral: the lender holds a lien or title interest until the loan is repaid. Because mortgages are secured by real estate, they typically carry lower interest rates than unsecured consumer loans.
Key points
- A mortgage can finance a primary home, secondary residence, or investment property.
- Interest can be fixed or adjustable; terms commonly range from 3 to 30 years (some loans extend 10–40 years).
- If a borrower defaults, the lender can foreclose and sell the property to recover the debt.
- Monthly payments typically include principal, interest, and often property taxes, homeowners insurance, and sometimes mortgage insurance (escrowed).
How mortgages work
Borrowers repay the loan in regular payments that cover:
* Principal — the loan balance being repaid.
* Interest — the cost of borrowing, calculated on the outstanding principal.
Over time, as principal is reduced, a larger share of each payment goes toward principal rather than interest.

Rate types:
* Fixed-rate mortgage — interest rate and monthly payment remain the same for the loan term.
* Adjustable-rate mortgage (ARM) — rate and payments can change periodically; initial rates are often lower than fixed rates but carry interest-rate risk for the borrower.
Legal mechanics:
* The lender places a lien on the property. If the borrower defaults, the lender may foreclose.
* Mortgage insurance (private or government-backed) may be required when the down payment is small to protect the lender.

Main types of mortgages
- Conventional loans
- Not backed by the federal government.
- Can be conforming (meeting Fannie Mae/Freddie Mac guidelines) or nonconforming.
- 
Private mortgage insurance (PMI) is commonly required when the down payment is under 20%. 
- 
FHA loans 
- Issued by private lenders and insured by the Federal Housing Administration.
- 
Lower credit and down payment requirements: for example, credit scores as low as 580 with 3.5% down, or 500 with 10% down (requirements vary by lender). 
- 
Specialty loans 
- VA loans — backed by the Department of Veterans Affairs; designed for eligible veterans and active-duty service members; often offer low or no down payment options.
- USDA loans — for eligible rural properties; can allow no down payment.
- Other specialty products may address particular borrower or property situations.
What a mortgage payment can include
A monthly mortgage payment may contain:
* Principal
* Interest
* Mortgage insurance (if required)
* Property taxes and homeowners insurance (often collected into an escrow account)
Other recurring obligations (e.g., homeowners association fees) may be collected separately or escrowed.
Upfront home-purchase costs are separate and can include earnest money, down payment, appraisal/inspection fees, prepaid items, and closing costs.

Getting a mortgage: typical steps
- Pre-qualification — informal estimate of how much you might borrow based on a summary of your finances; often free and can be done online or by phone.
- Pre-approval — formal application with documentation; lender verifies income, assets, debts, and credit and issues a conditional loan amount in writing.
- Find a home — make an offer and go through inspection and appraisal.
- Loan commitment/closing — lender issues a final loan approval after verifying the property and borrower; documents are signed and the lien is recorded.
Tip: Use a mortgage calculator to estimate monthly payments and total cost over the loan term.
Example
Borrow $300,000 with a conventional 30-year mortgage at 3.5% interest, with a $60,000 down payment and estimated monthly taxes and insurance:
* Estimated principal & interest payment: $1,377.71/month
* Total interest over 30 years: ~$147,974.61
* Example totals (including sample taxes and insurance) illustrate how interest, taxes, and insurance raise the overall cost of homeownership (figures will vary by situation).

Common questions
Is a mortgage the same as a home loan?
* Terms are often used interchangeably. More precisely, a mortgage is a loan secured by real property; a home loan is a mortgage used specifically to buy a house.
What credit score do I need to buy a house?
* Requirements vary by loan type and lender. FHA loans can accept lower scores (e.g., 500–580 range with higher down payments), while many conventional loans prefer scores of 620 or higher. Lenders also consider income, debt-to-income ratio, and other factors.

What happens if I default?
* The lender can initiate foreclosure, sell the property, and use proceeds to satisfy the loan. Foreclosure rules and timelines vary by state and loan type.
Bottom line
A mortgage is the primary way most people finance home purchases. Understanding loan types, payment components, the application process, and how interest and term affect total cost helps you compare options and make informed decisions when buying a home.
