Common Types of Mortgage Loans
Mortgage loans come in various types, each with unique features designed for different financial situations. Understanding the differences between these options is crucial for selecting the right mortgage for your needs.
| Mortgage Type | Description | Best For | Pros | Cons |
|---|---|---|---|---|
Fixed Rate | Interest rate remains constant throughout the loan term | Long-term homeowners who want payment stability | Predictable payments; Protection against rising rates | Higher initial rates than ARMs; Can't benefit from falling rates |
Adjustable Rate (ARM) | Rate adjusts periodically after initial fixed period | Short-term homeowners or those expecting falling rates | Lower initial rates; Potential for lower payments if rates drop | Payment uncertainty; Risk of rates increasing |
FHA Loan | Insured by Federal Housing Administration | First-time buyers with limited down payment savings | Lower down payment (3.5%); More lenient credit requirements | Mandatory mortgage insurance; Higher overall costs |
VA Loan | Guaranteed by Department of Veterans Affairs | Eligible veterans, service members, and spouses | No down payment required; No mortgage insurance | VA funding fee; Only for qualified service members |
Jumbo Loan | Exceeds conforming loan limits | Buyers of higher-priced homes in expensive markets | Finance high-value properties; Competitive rates | Stricter qualification requirements; Larger down payments |
Which Mortgage Type Is Right For You?
When comparing mortgage types, consider how long you plan to stay in the home, your comfort with payment changes, and your financial situation. Use our calculator to compare different loan scenarios and see which option aligns best with your budget and goals.
Understanding Mortgage Payment Components
Your monthly mortgage payment typically consists of multiple components, often remembered by the acronym PITI: Principal, Interest, Taxes, and Insurance. Understanding each component helps you better plan for your total housing costs.
The portion of your payment that reduces the original loan amount. Early in your loan, this is a smaller part of your payment, but gradually increases over time.
The cost of borrowing money from your lender. Initially, this makes up the largest portion of your payment, but decreases over the loan term as your principal balance reduces.
Property taxes assessed by local government. Often collected monthly by your lender and held in escrow until tax payments are due. These vary by location and property value.
Includes homeowners insurance and possibly mortgage insurance (PMI). Like taxes, these are often collected monthly and held in escrow until payments are due.
How Mortgage Payments Are Calculated
The principal and interest portion of your mortgage payment is calculated using a formula that accounts for the loan amount, interest rate, and loan term. Our calculator uses this standard formula:
M = P [ r(1+r)^n / ((1+r)^n)-1) ]
With each payment, a portion goes toward interest and the remainder reduces your principal. Early in your loan, more of your payment goes to interest, but this balance shifts over time, with more going to principal as your loan matures.
Factors That Influence Mortgage Rates
Mortgage interest rates fluctuate based on numerous economic and personal factors. Understanding what influences rates can help you time your home purchase or refinance more effectively.
Economic Factors
Federal Reserve Policy
When the Federal Reserve adjusts the federal funds rate, mortgage rates often follow. Rate increases typically lead to higher mortgage rates, while decreases can result in lower rates.
Inflation
Rising inflation erodes purchasing power, causing lenders to raise rates to maintain profit margins. Low inflation typically results in lower mortgage rates.
Economic Growth
Strong economic growth and low unemployment can lead to higher mortgage rates, while economic downturns often result in lower rates to stimulate borrowing.
Bond Market
Mortgage rates typically follow the yield on 10-year Treasury bonds. When bond yields rise, mortgage rates usually increase; when yields fall, rates tend to decrease.
Personal Factors
Credit Score
Higher credit scores typically qualify for lower interest rates. Lenders view borrowers with excellent credit as lower risk, offering them more favorable terms.
Down Payment
A larger down payment often results in better interest rates. Putting down 20% or more can eliminate PMI and may qualify you for lower rates.
Loan Term
Shorter-term loans (e.g., 15 years) typically have lower interest rates than longer-term loans (e.g., 30 years), but monthly payments will be higher.
Loan-to-Value Ratio
The ratio of your loan amount to the home's value affects your rate. Lower LTV ratios (meaning more equity) generally result in lower interest rates.
Tips for Securing a Better Mortgage Rate
Improve Your Credit Score
Pay down debt, make on-time payments, and correct any errors on your credit report. Aim for a score of 740+ for the best rates.
Save for a Larger Down Payment
Aim for at least 20% to avoid PMI and potentially qualify for better rates. Each additional 5% can sometimes further reduce your rate.
Compare Multiple Lenders
Shop around and get quotes from at least 3-5 lenders. Even a 0.25% difference in rates can save thousands over the loan term.
Consider Paying Points
Discount points are upfront fees paid to the lender to reduce your interest rate. Each point costs 1% of the loan amount and typically reduces your rate by 0.25%. Paying points makes sense if you plan to keep the loan for a long time, allowing you to recoup the upfront cost through lower monthly payments. Our calculator can help you determine if paying points is cost-effective for your situation.
Lock Your Rate
When you find a good rate, consider locking it in. Rate locks typically last 30-60 days and protect you if rates rise before closing.
Consider Different Loan Types
Compare fixed-rate and adjustable-rate options. ARMs often start with lower rates, which may be beneficial if you plan to move within a few years.
Frequently Asked Questions
How much house can I afford?
Most financial experts recommend that your mortgage payment (including principal, interest, taxes, and insurance) should not exceed 28% of your gross monthly income. Additionally, your total debt payments (including mortgage, car loans, student loans, etc.) should not exceed 36% of your income. Use our calculator to determine a comfortable monthly payment based on your income and existing debts.
Is it better to get a 15-year or 30-year mortgage?
A 15-year mortgage typically offers lower interest rates but higher monthly payments. You'll build equity faster and pay significantly less interest over the life of the loan. A 30-year mortgage has lower monthly payments, making it more affordable month-to-month, but you'll pay more interest over time. Consider your budget, financial goals, and how long you plan to stay in the home when deciding between the two.
What is private mortgage insurance (PMI)?
PMI is insurance that protects the lender if you default on your mortgage. It's typically required when your down payment is less than 20% of the home's value. PMI usually costs between 0.5% and 1.5% of your loan amount annually and is added to your monthly payment. Once you reach 20% equity in your home, you can usually request to have PMI removed.
How do points work when getting a mortgage?
Discount points are fees paid upfront to the lender to reduce your interest rate. Each point costs 1% of your loan amount and typically lowers your rate by 0.25%. Paying points makes sense if you plan to keep the loan for a long time, allowing you to recoup the upfront cost through lower monthly payments. Our calculator can help you determine if paying points is cost-effective for your situation.
Should I pay extra on my mortgage?
Making additional payments on your mortgage can significantly reduce your loan term and save thousands in interest. Even small extra payments can make a big difference over time. However, consider your overall financial situation first: prioritize high-interest debt, emergency savings, and retirement contributions before making extra mortgage payments. Use our calculator to see how additional payments could impact your loan.
When should I refinance my mortgage?
Refinancing may make sense if: (1) Current interest rates are at least 0.5-1% lower than your existing rate; (2) You plan to stay in your home long enough to recoup closing costs; (3) Your credit has improved significantly since your original mortgage; or (4) You want to change from an adjustable to a fixed-rate loan. Use our calculator to compare your current mortgage with refinancing options.
