02 What you need to know
Why a future refinance isn’t guaranteed
A refinance replaces your current mortgage with a new one, usually to get a lower rate or payment. It’s a brand-new loan, so you have to qualify again.
Rates may not cooperate
No one knows where mortgage rates will be in a year or five. They can fall, stay flat or rise.
You have to re-qualify
Even if rates drop, approval depends on your situation at that time:
- Credit: a lower score can mean a higher rate or no approval.
- Income: a job change, reduced hours, or a dip in self-employed income can change what you qualify for.
- Home value: a new appraisal decides your LTV (loan-to-value, the loan amount as a percentage of the home’s value). If values fall, you may not have enough equity.
- Property eligibility: a condo project’s approval status or the property’s condition can change.
- Seasoning: some programs require you to have owned the home or made payments for a set time before refinancing.
Refinancing costs money
You’ll usually pay lender fees, title, appraisal and escrow fees, plus prepaid interest and a new impound deposit. The question is how long it takes your monthly savings to cover those costs, called the break-even point.
| Item | Amount |
|---|---|
| Refinance costs | $6,000 |
| Monthly payment savings | $250 |
| Break-even ($6,000 ÷ $250) | 24 months |
Assumptions: hypothetical costs and savings for illustration. Your actual costs and savings depend on your loan, rate and property.
If you sell or refinance again before month 24 in this example, the refinance cost you more than it saved.
03 Real-world example
Example: stretching for a payment that needs rates to drop
Say you borrow $800,000 on a 30-year fixed loan at a hypothetical 7% rate. You’re comfortable with the payment you’d have at 6%, so you plan to refinance once rates fall a point.
| At hypothetical 7% | At hypothetical 6% | |
|---|---|---|
| Monthly principal & interest | $5,322.42 | $4,796.40 |
| Monthly gap vs. your comfortable budget | $526.02 | $0 |
| Gap over 1 year | $6,312.19 | $0 |
| Gap over 3 years | $18,936.57 | $0 |
Assumptions: $800,000 loan, 30-year fixed, principal and interest only (taxes, insurance and HOA not included). Rates are hypothetical and illustrative, not current offers. “Comfortable budget” is the 6% payment.
If rates don’t fall, you cover an extra $526.02 every month for as long as it takes, nearly $19,000 over three years. And even if rates do fall, you’d still need to qualify and pay refinance costs.
04 What most people overlook
What buyers overlook about refinancing later
- Prepayment penalties. Some loans, especially Non-QM and DSCR loans, can charge a fee if you pay off or refinance within the first few years. Ask before you sign.
- Your life may change. Going self-employed, taking leave or changing careers can make re-qualifying harder, even with good credit.
- A new loan restarts the clock. Refinancing into a new 30-year loan resets your payoff date, and closing costs can eat into savings.
- There are other ways to lower an early payment. A temporary buydown or paying points can reduce your payment now, without depending on future rates.
Buy with a payment you can live with today. Treat a future refinance as a bonus, not a requirement.
05 How I’d approach it
How I’d plan your payment without counting on a refinance
If rates drop, great, we’ll look at refinancing. But your budget should work on the day you close.
First, I ask what monthly payment you’re truly comfortable with, including taxes, insurance and HOA. Then I work backward to a price range using the payment calculator.
Next, I compare options that lower the payment now, like a seller-paid buydown, which I model in the buydown calculator.
Finally, I make sure the loan has no prepayment penalty, or a limited one you understand, so refinancing stays an option if the numbers ever make sense.
