A refinance replaces your current mortgage with a new one, ideally on better terms. Done right, it can save you real money or free up cash for a goal. Done on autopilot, it can cost you more than it saves while feeling like a win, because the savings are visible and the costs are buried. These are the five mistakes that catch people most often, and avoiding them is mostly a matter of doing a little math before you sign.
A lower rate is not automatically a good deal, because refinancing has closing costs just like your original loan. The number that matters is the break-even: divide what the refinance costs by how much it lowers your monthly payment, and that tells you how many months until you come out ahead. If the refinance costs $6,000 and saves $200 a month, you break even at 30 months. Refinance and then move or refinance again before that point, and you simply lost money. Always run the break-even, and be honest about how long you will keep the loan. Josh's team shops nearly 100 investors on every loan, and even the sharpest rate on the board fails this test more often than people expect.
If you are five years into a 30-year mortgage and you refinance into a fresh 30-year loan, you just added five years back onto your payoff. Your monthly payment might drop, but you could pay more total interest over the life of the loan even at a lower rate, simply because you stretched the timeline back out. It can still be the right move, but you have to look at the total cost, not just the monthly payment. One fix is to refinance into a shorter term, or to keep making your old higher payment on the new lower-rate loan so you stay on track.
A no cost refinance does not mean there are no costs. It means the costs were either rolled into your loan balance or covered by accepting a higher rate through a lender credit. Either way you are paying, just not at the closing table. That can be a perfectly good choice, especially if you expect to refinance again or move before the higher rate adds up, but only if you know that is the trade you are making. Treating it as genuinely free is how people end up surprised.
A cash-out refinance lets you borrow against your equity and take the difference in cash, which is useful for the right purpose, like a value-adding renovation or wiping out high-interest debt. The trap is using it to convert short-term spending into a 30-year obligation. Rolling credit cards into your mortgage can make sense mathematically, but if you run the cards back up you have doubled your problem and put your home behind it. And paying for a vacation or a car over 30 years means paying for it many times over.
Cash-out is a tool for building or consolidating, not for spending.
A refinance is a full loan, which means full underwriting. The same rules that applied when you bought apply again: the lender checks your credit, income, and equity, and re-verifies things late in the process. People relax because they already own the home, then open a new credit card, finance a car, or change jobs mid-refinance and watch their rate or approval change. Until the refinance closes, keep your financial life stable, just as you would on a purchase.
Before you move forward, answer three questions honestly.
A refinance that passes all three is usually a good one. A refinance that only looks good because the monthly payment dropped is exactly the kind that costs you. The math is not complicated, and running it is the difference between a smart refinance and an expensive one.

Stop guessing what you can really afford
Tell Josh and his team your situation, and you'll get the exact price range you qualify for, the loan that gets you the most home for your money, and a step-by-step plan to close. They handle your loan directly, never a referral, and go far beyond a basic pre-approval, so you stop second-guessing, tour with confidence, and write offers sellers take seriously.
Build my Roadmap →Run the break-even: divide the total cost of the refinance by the amount it lowers your monthly payment to see how many months until you come out ahead. If you expect to keep the loan longer than that, it likely makes sense. Also check the total interest over the life of the new loan, not just the monthly payment.
It can. Refinancing into a new 30-year loan resets your payoff timeline, so if you were several years into your old mortgage you add those years back. Your payment may drop while your total interest rises. Refinancing into a shorter term, or continuing to pay your old higher payment, avoids this.
No. The closing costs are either rolled into your new loan balance or offset by a higher interest rate through a lender credit. You still pay, just not up front. It can be a smart choice if you expect to move or refinance again soon, as long as you understand the trade.
It depends on the use. Borrowing against equity for a value-adding renovation or to consolidate high-interest debt can make sense. Using it to fund spending like vacations or cars stretches short-term purchases over 30 years, and consolidating credit cards backfires if you run the balances back up.
Yes. A refinance goes through full underwriting, and lenders re-check your credit, income, and employment, sometimes right before closing. Opening new credit, financing a large purchase, or changing jobs during the process can change your rate or sink the approval, so keep your finances stable until it closes.
