Complete Guide to Refinancing Your Mortgage
Learn how refinancing works, when it makes sense, and how to get the best rates to save money on your mortgage.

What is Mortgage Refinancing?
Mortgage refinancing is the process of replacing your existing mortgage with a new loan, typically to secure better terms or tap into your home's equity. When you refinance, you pay off your current mortgage and take out a new one, often with a different interest rate, term length, or loan amount.
At Homebux, we've helped thousands of homeowners successfully refinance their mortgages to achieve various financial goals, from lowering monthly payments to funding major expenses or investments.
- Lower your interest rate and monthly payment
- Shorten your loan term to pay off your mortgage faster
- Convert from an adjustable-rate to a fixed-rate mortgage
- Access home equity for major expenses or debt consolidation
- Remove private mortgage insurance (PMI)
Refinancing makes sense when:
- Interest rates have dropped significantly since you got your mortgage
- Your credit score has improved, qualifying you for better rates
- You plan to stay in your home long enough to recoup closing costs
- You have significant equity in your home (typically 20% or more)
Types of Mortgage Refinancing
There are several types of refinancing options available, each designed to meet different financial goals.
Rate-and-Term Refinance
The most common type of refinancing, a rate-and-term refinance replaces your current mortgage with a new one that has a different interest rate, term length, or both. The loan amount typically remains the same (except for closing costs, which may be rolled into the new loan).
Best for:
- Lowering your monthly payment by securing a lower interest rate
- Shortening your loan term to pay off your mortgage faster
- Switching from an adjustable-rate to a fixed-rate mortgage (or vice versa)
Cash-Out Refinance
A cash-out refinance allows you to borrow more than you currently owe on your mortgage and receive the difference in cash. This option taps into your home's equity, converting it into funds you can use for various purposes.
Best for:
- Home improvements or renovations
- Consolidating high-interest debt (credit cards, personal loans)
- Funding major expenses like education or medical bills
- Investment opportunities
Cash-In Refinance
The opposite of a cash-out refinance, a cash-in refinance involves bringing money to closing to pay down your loan balance. This reduces your loan-to-value ratio, which can help you qualify for better rates or eliminate private mortgage insurance.
Best for:
- Eliminating private mortgage insurance (PMI)
- Qualifying for a lower interest rate
- Reducing your monthly payment
- Homeowners who are underwater on their mortgage
Streamline Refinance
Available for FHA, VA, and USDA loans, streamline refinancing offers simplified documentation requirements and often doesn't require a home appraisal. These programs are designed to make refinancing faster and less expensive for qualified borrowers.
Best for:
- Current FHA, VA, or USDA loan holders
- Homeowners who want to minimize closing costs
- Those seeking a faster, simpler refinancing process
When to Consider Refinancing
Timing is crucial when it comes to refinancing. Here are some scenarios when refinancing might make financial sense:
Interest Rates Have Dropped
One of the most common reasons to refinance is when market interest rates fall significantly below your current mortgage rate. As a general rule, consider refinancing if you can reduce your interest rate by at least 0.5 to 1 percentage point, though even smaller reductions can be worthwhile in some cases.
Example Savings:
On a $300,000, 30-year mortgage, reducing your interest rate from 5% to 4% could save you approximately $170 per month and over $60,000 in total interest over the life of the loan.
Your Credit Score Has Improved
If your credit score has increased significantly since you took out your original mortgage, you might qualify for a better interest rate now. Even if market rates haven't changed much, your improved creditworthiness could lead to substantial savings.
You Want to Change Your Loan Term
Refinancing can help you adjust your loan term to better align with your financial goals:
- Shortening your term: If you can afford higher monthly payments, refinancing from a 30-year to a 15-year mortgage can help you pay off your home faster and save tens of thousands in interest.
- Extending your term: If you're struggling with high monthly payments, refinancing to a longer term can provide immediate relief by lowering your monthly obligation (though you'll pay more interest over time).
You Need to Tap Into Home Equity
If you've built up significant equity in your home and need funds for major expenses, a cash-out refinance might be appropriate. This can be a cost-effective way to access funds compared to other forms of borrowing, especially for:
- Home improvements: Renovations that increase your home's value can be a good use of equity, potentially offering tax benefits as well.
- Debt consolidation: Replacing high-interest debt with a lower-rate mortgage can save money and simplify your finances.
- Education expenses: Using home equity can be less expensive than some student loan options.
You Want to Switch Loan Types
Refinancing allows you to change between different types of mortgages:
- From adjustable to fixed-rate: If you have an adjustable-rate mortgage (ARM) and interest rates are expected to rise, or you simply want more payment stability, refinancing to a fixed-rate mortgage can provide peace of mind.
- From fixed to adjustable-rate: If you don't plan to stay in your home long-term, switching to an ARM with a lower initial rate could save you money during your remaining time in the home.
- From FHA to conventional: If you've built up 20% equity and improved your credit, refinancing from an FHA loan to a conventional loan can eliminate mortgage insurance premiums.
Calculate Your Break-Even Point
To determine if refinancing makes financial sense, calculate your break-even point—the time it takes for your monthly savings to exceed the cost of refinancing:
Break-Even Point = Total Closing Costs ÷ Monthly Savings
For example, if refinancing costs $4,000 and saves you $200 per month, your break-even point is 20 months. If you plan to stay in your home longer than that, refinancing likely makes sense.
