How to Refinance Co-borrowed Home Loans in Philippines 2026

A co-borrowed home loan — sometimes called a joint home loan — is a mortgage where two or more individuals are listed as co-borrowers and share equal legal responsibility for repaying the debt. Unlike a co-maker or guarantor (who only steps in if the primary borrower defaults), all co-borrowers are equally liable from day one, and all of their income is counted toward the combined gross monthly income (GMI) used to qualify for the loan.

In the Philippines, co-borrowed home loans are most commonly taken out by:

• Married couples — to combine incomes and qualify for a higher loan amount or better terms
• Siblings or adult children with parents — especially for inherited or family properties
• Unmarried partners or live-in couples — though some banks impose additional requirements in this case
• Business partners or co-investors — for property purchased as a shared asset

Because all co-borrowers are named on the Title (Transfer Certificate of Title or Condominium Certificate of Title), any major financial decision about the property — including refinancing — requires the participation and consent of all parties.

Yes, you can refinance a co-borrowed home loan in the Philippines. The process follows the same fundamental steps as refinancing a solo loan — you apply to a new lender, they appraise the property, pay off your old loan, and issue a new one at better terms. However, there are several important differences to be aware of:

• All co-borrowers must participate in the application. Every person listed on the original loan and/or title will need to sign documents and provide their own financial records.
• All co-borrowers must qualify under the new lender's criteria. If one co-borrower's financial situation has deteriorated since the original loan, it may affect your eligibility or the rate offered.
• The loan structure can change at refinancing. You may choose to maintain the same co-borrower arrangement, remove a co-borrower, or add a new one — each option has different legal and documentary requirements.

Philippine banks including BDO, BPI, Security Bank, Metrobank, and RCBC all accommodate co-borrowed refinance applications. Nook works with all of these lenders and can submit your application to multiple banks simultaneously, comparing offers on your behalf — at no cost to you.

Yes — in virtually all cases, both (or all) co-borrowers must consent to and actively participate in a refinancing transaction. Here's why this is non-negotiable:

• Legal liability: Because all co-borrowers are equally responsible for the debt, no single co-borrower can unilaterally replace or modify that obligation without the others' agreement.
• Title requirement: All names on the Transfer Certificate of Title (TCT) or Condominium Certificate of Title (CCT) must sign the real estate mortgage (REM) documents executed in favour of the new lender.
• Bank policy: Lenders will not release funds to pay off the old loan unless all borrowers on the original loan have signed off on the discharge of the old mortgage and the execution of the new one.

If a co-borrower is unwilling to cooperate — for example, in the case of a separation or family dispute — your options become more limited. You would generally need to resolve the co-ownership arrangement through legal means (such as a partition or buy-out) before a bank will process the refinance. If this applies to your situation, it's worth speaking to both a lawyer and a mortgage specialist like Nook to understand what's possible.

If one co-borrower is living or working abroad, they can typically participate via a Special Power of Attorney (SPA) authorising a representative in the Philippines to sign documents on their behalf. Most banks require the SPA to be notarised and authenticated (apostilled if from a non-Hague country) before acceptance.

Yes, refinancing is one of the most practical ways to remove a co-borrower from a home loan in the Philippines — for example, after a separation, or when one party wants to exit the arrangement. The process essentially involves the remaining borrower qualifying for the new loan entirely on their own (or with a different co-borrower), so the original co-borrower's name is no longer tied to any mortgage obligation.

Key requirements to remove a co-borrower:

• The remaining borrower must qualify independently for the new loan amount. The lender will assess their income, creditworthiness, and debt-to-income ratio without counting the departing co-borrower's income.
• If the property title is in both names, a deed of absolute sale or deed of donation (depending on the relationship and arrangement) is typically required to transfer the departing co-borrower's share of the title to the remaining borrower before or in parallel with the refinance.
• Capital Gains Tax (6% of the selling price or zonal value, whichever is higher), Documentary Stamp Tax, and transfer fees may apply to the title transfer, adding to the overall cost.
• The departing co-borrower must cooperate and sign all relevant documents.

This process is more administratively complex than a standard refinance, so timeline and costs will be higher. Expect the process to take 3 to 6 months depending on the bank and the complexity of the title situation. Despite the added complexity, the savings from securing a lower interest rate can still make this well worth pursuing.

Yes, adding a co-borrower at refinancing is allowed by most Philippine banks and can actually strengthen your application — particularly if the new co-borrower has a stable income that helps you qualify for a larger loan or a better interest rate.

Common scenarios where borrowers add a co-borrower at refinancing include:

• A spouse who was not on the original loan (perhaps because they were not yet employed or were earning less at the time)
• An adult child who has started earning and wants to help reduce the family's mortgage burden
• A new partner after a separation, once the original co-borrower's name has been addressed

What the new co-borrower needs to provide:

• Valid government-issued IDs
• Proof of income (payslips for the last 3 months, ITR, Certificate of Employment — or audited financial statements if self-employed)
• Latest income tax return (BIR Form 2316 or 1701)
• Credit history check (the bank will pull a credit report)

If the new co-borrower is also being added to the property title, additional legal steps — including a deed of co-ownership and the associated taxes and transfer fees — will be required. Not all borrowers choose to update the title when adding a co-borrower, but banks will clarify their requirements on a case-by-case basis.

The documentary requirements for a co-borrowed refinance application are more extensive than a single-borrower application because each co-borrower must submit their own personal and financial documents. Below is a comprehensive checklist:

For each co-borrower:

• Two valid government-issued IDs (e.g., passport, driver's licence, PhilSys ID, PRC ID)
• Filled-out bank application form
• Certificate of Employment and Compensation (for employed individuals)
• Latest 3 months' payslips
• Latest ITR with BIR stamp (BIR Form 2316 for employees; BIR Form 1701 for self-employed)
• Audited Financial Statements for the last 2 years (for self-employed or business owners)
• Marriage certificate (if married co-borrowers), or birth certificate (for parent-child arrangements)
• Special Power of Attorney if any co-borrower will be represented by a third party

Property documents (shared):

• Original or certified true copy of the Transfer Certificate of Title (TCT) or Condominium Certificate of Title (CCT)
• Latest tax declaration and real property tax receipts (Amilyar)
• Vicinity map and lot plan (certified by a licensed geodetic engineer for house and lot)
• Copy of the existing loan statement showing outstanding balance
• Floor plan (for condominium units)

Banks may request additional documents depending on your specific situation. Nook provides a personalised checklist and helps you prepare everything correctly before submission — reducing delays and back-and-forth with the bank.

The savings potential from refinancing depends on your current interest rate, outstanding loan balance, and remaining loan term. Here are three realistic examples for co-borrowed loans in the Philippines, comparing a current rate of 8.5% p.a. against Nook's best available refinance rate of 5.99% p.a.:

Example 1 — Couple with a 3,000,000 loan, 20-year term:

• Monthly payment at 8.5%: approximately 26,060
• Monthly payment at 5.99%: approximately 21,480
• Monthly savings: approximately 4,580
• Total savings over 5 years: approximately 274,800

Example 2 — Siblings with a 5,000,000 loan, 20-year term:

• Monthly payment at 8.5%: approximately 43,430
• Monthly payment at 5.99%: approximately 35,800
• Monthly savings: approximately 7,630
• Total savings over 5 years: approximately 457,800

Example 3 — Parent and adult child with a 7,500,000 loan, 25-year term:

• Monthly payment at 8.5%: approximately 60,050
• Monthly payment at 5.99%: approximately 48,280
• Monthly savings: approximately 11,770
• Total savings over 5 years: approximately 706,200

Keep in mind that refinancing does carry one-time fees — typically appraisal fees, documentary stamp tax, notarial fees, and mortgage registration — which usually total between 1% and 2% of the loan amount. Even accounting for these costs, borrowers typically break even within 12 to 24 months and save substantially over the life of the loan.

Most major Philippine banks accept co-borrowed refinance applications. Here's a quick overview of key lenders and their general stance on co-borrower arrangements:

• BDO — Accepts co-borrowers who are immediate family members (spouse, parents, children, siblings). Non-related co-borrowers assessed case by case.
• BPI — Accepts spousal and family co-borrowers; has a streamlined process for refinancing existing BPI loans and competitor loans.
• Security Bank — Known for competitive rates; accepts co-borrowers and is generally flexible on co-borrower relationships.
• Metrobank — Accepts family co-borrowers; thorough underwriting process with competitive fixed-rate periods.
• RCBC — Accepts co-borrowers; offers competitive re-pricing deals for refinances from other banks.
• UnionBank — Digital-forward process; accepts co-borrowers and has competitive promotional rates.
• PNB — Government-affiliated bank with competitive rates; accepts family co-borrowers.
• Chinabank — Accepts co-borrowers; known for efficient processing in some branches.
• Pag-IBIG (HDMF) — Government fund that accepts co-borrowers for both its own loans and for refinancing Pag-IBIG loans to private banks. Note that Pag-IBIG requires co-borrowers to also be Pag-IBIG members with sufficient contributions.

Each bank has slightly different maximum loan-to-value (LTV) ratios, income requirements, and eligible co-borrower relationships. Rather than applying to each bank separately, Nook submits your profile to multiple lenders and presents you with the best offers — saving you time and keeping your credit inquiries to a minimum.

This is one of the most common concerns for co-borrowed refinance applicants. When two co-borrowers have significantly different financial profiles — for example, one has a strong credit score and stable income while the other has a patchy credit history or irregular income — the bank will assess the combined application and typically base its decision on the weaker of the two profiles in terms of risk.

Here's what this means in practice:

• Lower credit score co-borrower: If one co-borrower has missed payments on credit cards or other loans, this can result in a higher interest rate being offered or the application being declined altogether by certain banks. Some banks focus more on payment history on the existing home loan itself rather than unsecured credit behaviour.
• Irregular income co-borrower: Self-employed or freelance co-borrowers may face stricter income verification requirements. Banks typically want to see 2 years of consistent income as evidenced by ITRs and financial statements.
• One co-borrower is unemployed or retired: Some banks will simply exclude that co-borrower's income from the calculation rather than penalise the application, particularly if the remaining borrower qualifies on their own.

If bad credit is a concern for one of your co-borrowers, it may be worth reading our guide on refinancing with bad credit in the Philippines for strategies that can help strengthen your overall application before you apply.

Nook's mortgage specialists assess your combined profile before submitting applications, so we match you with lenders most likely to approve your specific situation — avoiding unnecessary rejections.

A standard co-borrowed refinance — where the borrowers and co-borrower arrangement remain unchanged — typically takes 6 to 10 weeks from application to loan release, assuming documents are complete and no complications arise.

Here is a typical timeline breakdown:

• Week 1–2: Document preparation and submission. All co-borrowers gather their requirements and submit to Nook, who packages and forwards to the chosen bank(s).
• Week 2–3: Bank credit evaluation. The bank reviews the combined income and credit profile of all co-borrowers. This stage may involve back-and-forth for additional documents.
• Week 3–4: Property appraisal. The bank sends an appraiser to assess the current market value of the property.
• Week 4–5: Loan approval and offer letter. Once approved, the bank issues a Letter of Approval (LOA) detailing the rate, term, fees, and conditions.
• Week 5–7: Legal documentation. Loan documents are prepared, reviewed, and signed by all co-borrowers. A notary public is involved.
• Week 7–10: Loan release and registration. The new bank pays off the old lender, the old mortgage is discharged, and the new real estate mortgage is registered with the Registry of Deeds.

Timelines extend when co-borrowers need to arrange a Special Power of Attorney (adding 2–4 weeks if the SPA must be apostilled from abroad), when title issues need resolution, or when a co-borrower change is involved (removing or adding a co-borrower can add 4–8 weeks due to title transfer requirements).

Working with Nook helps keep the process on track — we follow up with the bank on your behalf, flag missing documents early, and coordinate all parties to avoid unnecessary delays.
