Is refinancing worth it? Trade-offs for homeowners

Key takeaways

• Refinancing comes with real upfront costs, typically 2% to 3% of the loan amount, so the break-even point should always be calculated before moving forward. 
• The financial benefit depends heavily on how long a homeowner plans to stay. The longer the stay, the more time there is to recover costs and benefit from a lower rate. 
• Equity, credit standing and current tax implications all affect whether refinancing is possible and whether it makes financial sense.  

If you’re a homeowner with no plans to move anytime soon, refinancing can be an appealing way to lower your monthly payment or adjust the terms of your mortgage. But while refinancing can make financial sense, it isn’t always simple or cost effective.

When a homeowner refinances, the original mortgage gets paid off and replaced with a new loan. The new loan comes with its own interest rate, term length and monthly payment. The goal is usually to improve at least one of those factors — though the right trade-off depends entirely on the homeowner's financial situation and long-term plans.

Refinancing isn't always the right move, but there are clear scenarios where it works in a homeowner's favor.

• Interest rates have dropped significantly: A common guideline is that refinancing becomes worth considering when the new rate is at least 1% lower than the current one. The larger the difference, the faster the upfront costs get recovered through monthly savings.
• A long-term stay is in the cards: The longer a homeowner stays, the more time there is to benefit from a lower payment. If the break-even point is three years and there are no plans to move, that's a solid case to move forward.
• Switching from an adjustable to a fixed rate makes sense: Adjustable-rate mortgages, or ARMs, can start with lower rates, but those rates can rise over time. Refinancing into a fixed-rate loan provides stability and protection against future rate increases.
• The goal is to shorten the loan term: Some homeowners refinance from a 30-year to a 15-year mortgage. The monthly payment might be higher, but far less interest gets paid over the life of the loan and equity builds faster.
• Cash flow needs some breathing room: If financial circumstances have changed and a lower monthly payment would meaningfully help the budget, refinancing could be worth the upfront cost even if the rate difference is modest.

Many homeowners are surprised to learn that refinancing isn’t free. Even though you’re replacing an existing loan, lenders typically treat a refinance much like a new mortgage. That means borrowers may have to pay for closing costs, which often run about 2% to 3% of the loan amount.

On a $150,000 refinance, that could mean roughly $3,000 to $4,500 out of pocket. Those costs may include lender fees, title insurance and an appraisal. Some borrowers roll those expenses into the loan balance, but doing so increases the total amount borrowed and the interest paid over time.

Homeowners who itemize their deductions can deduct mortgage interest, which lowers taxable income. Refinancing to a lower interest rate typically reduces the amount of interest paid each year and with it, the size of that deduction.

For some borrowers, the impact is minimal. For others, especially those with larger loans, the change could be more noticeable. Homeowners concerned about the tax implications of refinancing may want to consult a certified public accountant before moving forward.

Most lenders require an appraisal during the refinance process to verify the home’s market value. Appraisals typically cost several hundred dollars and are paid by the homeowner.

In some cases, lenders may waive the appraisal requirement, particularly if the borrower has strong credit and significant equity in the home. But homeowners shouldn’t assume an appraisal will be skipped, especially if home values in the area are uncertain.

Lenders generally require homeowners to have a certain amount of equity to qualify for a refinance. Equity is the portion of the home you own outright, calculated as the home’s market value minus the remaining mortgage balance.

Homeowners who owe more than their home is worth — often referred to as being “underwater”— may not qualify for a refinance. Equity requirements vary by lender, which is why speaking with a loan officer early in the process can help set realistic expectations.

Due to refinancing coming with upfront costs, it works best for homeowners who plan to stay put long enough to recoup those expenses through lower monthly payments. If you sell the home after just a year or two, the savings may not outweigh the cost of refinancing — especially when you factor in closing costs paid again at the time of sale.

Some homeowners try to reduce upfront costs by accepting a slightly higher interest rate in exchange for lender credits that help cover closing costs. That approach can make sense for borrowers who expect to move in the near term, but it typically results in higher payments over the life of the loan.
