When your bank offers to refinance your home loan, it can feel a little puzzling. Why would a lender want to give you a lower interest rate? Isn't that less money for them? The truth is, refinancing is a two-sided transaction — banks have very clear business reasons for offering it, and when you understand those reasons, you become a much smarter borrower. This guide breaks down the lender's perspective in plain language, so you can walk into any refinancing conversation knowing exactly what's on the table.
Whether you're currently paying 8%, 9%, or even 10% on your existing home loan, knowing why banks refinance loans gives you the insight to negotiate better terms, choose the right lender, and — most importantly — stop overpaying. Nook works with leading Philippine banks to find you the lowest available rate, currently as low as 5.99% p.a., completely free of charge to you as the borrower.
Banks offer refinancing primarily to win and retain customers. When a competitor offers a lower interest rate, your current bank risks losing your loan — and all the interest income that comes with it — entirely. By offering to refinance your loan, either at a lower rate or on better terms, they keep you as a customer and continue earning interest revenue over the remaining loan term.
For banks that don't currently hold your loan, refinancing is a powerful customer acquisition tool. They're essentially saying: "Switch to us, and we'll reward you with a better rate." In a competitive lending market like the Philippines — where BDO, BPI, Metrobank, Security Bank, RCBC, and others are all fighting for mortgage business — this competition works directly in your favour as a borrower.
Yes — in almost every case. Even if a bank offers you a lower interest rate than you're currently paying, they are still earning a spread (profit margin) between the rate they offer you and the cost at which they fund that loan. For example, if a bank offers you 5.99% p.a. but their cost of funds is 3.5%, they're still earning approximately 2.49% annually on your outstanding balance.
Banks also earn ancillary revenue from refinancing through processing fees, appraisal fees, mortgage registration fees, and the cross-selling of related products like home insurance, credit cards, or savings accounts. So while it may look like generosity on the surface, refinancing is a calculated and profitable business decision for lenders — which is exactly why the offer is always available if you know where to look.
There are several reasons a bank may offer you a lower rate than your current one. First, market interest rates change over time. If you took out your home loan five or seven years ago, rates may have been significantly higher than they are today, and a new lender can offer current market pricing to attract your business.
Second, your financial profile may have improved since you first borrowed. If your income is higher, your credit history is stronger, and your loan-to-value ratio has decreased (because your property has appreciated or you've paid down principal), you are now a lower-risk borrower. Lower risk means lenders are willing to offer you a better rate. Third, competition among banks means that winning a good borrower — someone with an established repayment track record — is valuable enough for a lender to price aggressively. You've already proven you can service a home loan. That makes you a desirable customer.
Most major Philippine banks offer home loan refinancing, including BDO, BPI, Metrobank, Security Bank, PNB, RCBC, UnionBank, Chinabank, PSBank, Robinsons Bank, and EastWest Bank. Government-backed lenders like Landbank and Pag-IBIG (HDMF) also have refinancing programs, though their terms and eligibility criteria differ from private banks.
It's worth noting that the rates, lock-in periods, and fees vary significantly from one institution to another. A rate advertised by one bank may come with a two-year lock-in and a 2% pre-termination penalty, while another bank's slightly higher headline rate might offer more flexible terms. This is exactly why comparing across multiple lenders — rather than approaching just one bank directly — leads to better outcomes. If you're currently on a Pag-IBIG loan, for instance, refinancing your Pag-IBIG home loan to a private bank can unlock significantly lower rates that Pag-IBIG itself doesn't offer.
These two terms are often confused, but they are meaningfully different. Repricing is when you renegotiate the interest rate on your existing loan with your current bank — the loan itself stays the same, only the rate changes. Refinancing involves taking out a completely new loan, often with a different bank, to pay off your existing loan. The new loan comes with new terms, a new rate, and typically a new loan period.
Repricing is simpler and faster, but your current bank has less incentive to give you the best possible rate because you're already their customer — they know it's inconvenient for you to leave. Refinancing introduces genuine competition: you're shopping your loan to multiple lenders, and the one that wants your business most will offer the sharpest rate. In most cases, borrowers who refinance to a new bank secure lower rates than those who simply reprice with their existing lender.
Yes, absolutely — and this is often where the best rates are found. You are not obligated to stay with your current lender. As long as your lock-in period has expired (most Philippine home loans have a lock-in of one to three years), you are free to refinance with any bank that approves your application.
The process involves the new bank paying off your outstanding loan balance to your current bank, after which your mortgage is registered under the new lender. There are costs involved — mortgage cancellation and re-registration fees, documentary stamp tax, and possibly a processing fee — but in most cases, the monthly savings from a lower interest rate far outweigh these one-time costs within the first year or two. Nook helps you calculate this break-even point so you always know whether switching makes financial sense before you commit.
Banks assess refinancing applications using largely the same criteria as they use for new home loan applications, though the fact that you have an existing repayment history works in your favour. Key factors include: your current income and employment stability, your debt-to-income ratio (how much of your monthly income goes toward all debt payments), your credit history and any missed payments, the current appraised value of the property (which determines your loan-to-value ratio), and the remaining balance on your existing loan.
Banks generally prefer a loan-to-value ratio of 80% or below — meaning your outstanding loan is no more than 80% of your property's current market value. If your property has appreciated significantly since you first purchased it, this ratio may have improved considerably, making you a stronger refinancing candidate than when you first applied. Having a clean repayment record over the life of your existing loan is one of the most important signals you can send to a prospective new lender.
Not always — and that honesty matters. Refinancing makes strong financial sense when: the new interest rate is meaningfully lower than your current rate (generally 1% or more), you have enough remaining loan term to recoup the switching costs through monthly savings, and your lock-in period has already expired so you won't face pre-termination penalties from your current bank.
Refinancing is less likely to be worth it if you're very close to paying off your loan (because interest costs are already low at the tail end of an amortising loan), if the switching costs are unusually high, or if the new loan comes with a very long new term that increases your total interest paid over time. A good mortgage broker will run the numbers honestly and tell you if refinancing doesn't make sense in your specific situation — even if that means they don't earn a referral fee. At Nook, we show you the full picture before you decide.
The savings can be substantial. Consider a borrower with an outstanding home loan balance of 4,000,000 pesos and 20 years remaining, currently paying 8.5% p.a. Their monthly repayment would be approximately 34,732 pesos. If they refinance to a rate of 5.99% p.a. on the same remaining term, their new monthly repayment drops to approximately 28,621 pesos — a monthly saving of around 6,111 pesos, or more than 73,000 pesos per year. Over a 5-year period before the next rate review, that's over 366,000 pesos in savings, even after accounting for typical switching costs of 60,000 to 100,000 pesos.
For borrowers on even higher rates — and many Filipino homeowners are still paying 9% or 10% on older loans — the savings are even larger. The exact figure depends on your outstanding balance, remaining term, current rate, and the fees involved, which is why a personalised calculation is always more useful than a general estimate. Nook provides this calculation for free, with no obligation to proceed.
