Frequently Asked Questions

How is my monthly mortgage payment calculated?

Your monthly payment is calculated using the loan amount (property price minus down payment), interest rate, and loan term. The formula accounts for principal and interest payments over the life of the loan using the standard amortization formula.

What is an amortization schedule?

An amortization schedule shows how each monthly payment is split between principal and interest over the life of your loan. Early payments have more interest, while later payments have more principal as you pay down the balance.

How much should I put down on a house?

A typical down payment ranges from 3% to 20% of the home price. A 20% down payment helps you avoid private mortgage insurance (PMI) and reduces your monthly payment. However, many programs allow smaller down payments for qualified buyers.

What is PMI and when do I need it?

Private Mortgage Insurance (PMI) is required when you put down less than 20% on a conventional loan. PMI typically costs 0.3% to 1.5% of your loan amount annually. You can remove PMI once you reach 20% equity in your home through payments or appreciation.

Should I choose a 15-year or 30-year mortgage?

A 15-year mortgage has higher monthly payments but lower total interest costs and faster equity building. A 30-year mortgage offers lower monthly payments but higher total interest. Choose based on your budget, financial goals, and cash flow needs.

What credit score do I need for a mortgage?

Most conventional loans require a 620+ credit score, while FHA loans accept scores as low as 580 (or 500 with 10% down). Higher scores get better interest rates. VA and USDA loans have flexible credit requirements but typically prefer 620+.

How much house can I afford based on my income?

A general rule is that your total monthly housing costs shouldn't exceed 28% of your gross monthly income. Your total debt payments (including the mortgage) shouldn't exceed 36-43% of your income, depending on the loan program.

What's the difference between pre-qualification and pre-approval?

Pre-qualification is an estimate based on self-reported information. Pre-approval involves document verification and credit checks, giving you a conditional commitment for a specific loan amount. Pre-approval carries more weight with sellers.

Should I pay points to lower my interest rate?

Discount points cost 1% of your loan amount and typically reduce your rate by 0.25%. Pay points if you plan to stay in the home long enough to recoup the upfront cost through monthly savings (usually 5-7 years).

What are closing costs and how much should I expect?

Closing costs typically range from 2-5% of your home's purchase price and include appraisal fees, title insurance, attorney fees, loan origination fees, and prepaid taxes and insurance. Ask your lender for a Loan Estimate within three days of applying.

Can I get a mortgage if I'm self-employed?

Yes, but you'll need to provide additional documentation like tax returns (typically 2 years), profit and loss statements, and bank statements. Self-employed borrowers may face stricter requirements and should work with experienced lenders.

What happens if interest rates change after I apply?

You can lock your interest rate for 30-60 days (sometimes longer) after applying. Rate locks protect you from increases but may prevent you from benefiting from decreases. Some lenders offer float-down options for a fee.

Is it better to get a mortgage from a bank or mortgage broker?

Banks offer their own loan products, while brokers shop multiple lenders for you. Brokers may find better rates and terms but charge fees. Banks may offer relationship discounts. Compare offers from both to find the best deal for your situation.

When should I consider refinancing my mortgage?

Consider refinancing when rates drop 0.5-1% below your current rate, you want to switch loan terms, remove PMI, or access home equity. Calculate the break-even point by dividing closing costs by monthly savings to ensure it makes financial sense.

Understanding Your Mortgage Payment Components

Your monthly mortgage payment typically includes four main components, often called PITI:

Principal: The amount that goes toward paying down your loan balance

Interest: The cost of borrowing money from your lender

Taxes: Property taxes collected by your local government

Insurance: Homeowners insurance and PMI (if applicable)

How to Use Our Mortgage Calculator Effectively

Smart Tips for Home Buyers

Down Payment Strategies

While 20% down is ideal to avoid PMI, many successful homebuyers use smaller down payments:

Conventional loans: As low as 3% down for qualified buyers
FHA loans: 3.5% down payment option
VA loans: 0% down for eligible veterans
USDA loans: 0% down for rural properties

Interest Rate Impact

Even small changes in interest rates significantly affect your monthly payment and total loan cost. A 1% increase in interest rate on a $400,000 loan can add over $200 to your monthly payment and $80,000+ in total interest over 30 years.

Common Mortgage Calculator Mistakes to Avoid

❌ Forgetting Additional Costs

Don't forget property taxes, insurance, HOA fees, and maintenance costs when budgeting.

❌ Using Outdated Interest Rates

Interest rates change frequently. Always use current rates for accurate calculations.

❌ Ignoring PMI

Private mortgage insurance adds to your monthly payment if you put down less than 20%.

❌ Maxing Out Your Budget

Leave room in your budget for unexpected expenses and lifestyle changes.

When to Consult a Mortgage Professional

While mortgage calculators provide excellent estimates, consider speaking with a mortgage professional when:

You have unique financial circumstances (self-employed, irregular income)
You're considering complex loan products (ARM, jumbo loans)
You need help understanding different loan programs
You're ready to get pre-approved for a mortgage
