Commission-Based Sales Professional Home Loan Refinancing Guide

Can Commission-Based Sales Professionals Refinance Their Home Loan?

Yes — and more Filipino sales professionals do it successfully than you might think. Whether you're a real estate broker earning transaction commissions, a pharmaceutical sales rep with quarterly bonuses, an insurance agent building a renewal book, or a top-performing car salesperson, you absolutely can refinance your home loan to a lower rate. The process just requires a bit more preparation than a salaried employee would need.

The good news: the best refinance rate currently available through Nook is 5.99% per annum. If your current home loan is sitting at 8%, 9%, or even 10% — rates that are extremely common for loans taken out 3 to 5 years ago — the monthly savings can be significant enough to change your financial picture entirely.

This guide walks you through exactly what banks look for when evaluating commission-based income, which documents you need to prepare, and how to position your application for the strongest possible outcome.

Why Banks View Commission Income Differently

Banks are fundamentally in the business of predicting future income. When a borrower earns a fixed monthly salary, that prediction is easy. When income is commission-based, the bank has to work harder — and they respond by asking for more documentation and applying more scrutiny to what they receive.

This does not mean commission earners are disadvantaged. It means the way you prove your income matters more than the income itself. A sales professional earning 350,000 pesos per month in commissions who submits well-organized, complete documentation will almost always get approved. The same person submitting incomplete or inconsistent paperwork will face delays, counter-offers, or outright declines.

Understanding the bank's perspective helps you prepare correctly. They want to see three things: consistency of income over time, a credible basis for that income continuing, and tax compliance that aligns with what you're claiming to earn.

The Documentation Strategy for Commission Earners

Bureau of Internal Revenue (BIR) Records Are Your Foundation

For commission-based professionals, your BIR records are arguably the most important part of your application. Banks will look at your Income Tax Returns (ITR) — specifically your BIR Form 1701 or 1701A for self-employed commission earners, or Form 2316 plus 1700 for those employed with commission top-ups — to establish a baseline of declared income.

The critical point: the income you declare in your ITR must be high enough to support the loan you're applying for. If you're earning 200,000 pesos monthly in commissions but declaring only 50,000 pesos in your ITR, the bank will lend based on the declared figure, not the actual figure. This is why tax compliance is not just a legal obligation — it's a financial tool that directly affects your borrowing capacity.

Prepare at least two years of ITRs. Three years is even better, as it demonstrates a sustained income trend rather than a single good year.

Commission Vouchers and Payslips

If you receive commissions through an employer (common in insurance, real estate, and pharmaceutical sales), request official commission vouchers or payslips covering the last 12 months. Compile these into a single organized folder, sorted chronologically. Banks want to see the pattern of payments — the months where income was higher, the slower months, and the overall trajectory.

For agents operating under independent contractor arrangements, your agency or principal company can issue a certification of commissions paid. This is a simple letter on company letterhead confirming your relationship with the company and the total commissions paid over a specified period. Many banks will accept this alongside bank statements.

Bank Statements Are Powerful Evidence

Your personal bank statements for the last 12 months serve as a real-world record of cash flow. Commission deposits typically show up as large, irregular credits — which is exactly what banks expect to see from a commission earner. Make sure the account you submit is the one where commissions are actually deposited.

A common mistake: submitting bank statements from an account used primarily for expenses, where the balance stays low. If possible, maintain a dedicated account for commission receipts that clearly shows income flowing in. A 12-month average of credits in this account becomes a key data point for your loan officer.

Employment Certificate or Principal Relationship Letter

If you're employed with a company (even partly on commission), get a Certificate of Employment that specifies both your base salary and your average commission earnings. Ask HR to include the average commission figure explicitly — "basic salary of 25,000 per month plus average commissions of 180,000 per month" is far more useful than a generic employment certificate.

If you're an independent contractor or broker, a letter from your principal company confirming the ongoing nature of the relationship and typical commission levels serves a similar purpose.

How Banks Calculate Your Qualifying Income

Different banks use slightly different methodologies, but a common approach for commission earners is to average your income over 12 or 24 months. This smooths out the variability and gives the bank a conservative but defensible figure to work with.

Here's a practical example. Suppose your commissions over the last 12 months were: 120,000 / 95,000 / 210,000 / 180,000 / 75,000 / 310,000 / 240,000 / 190,000 / 85,000 / 270,000 / 220,000 / 165,000. The total is 2,160,000 pesos, giving a monthly average of 180,000 pesos. The bank would use approximately 180,000 pesos as your qualifying monthly income and apply their debt-to-income ratio — typically allowing up to 30-40% of this figure for mortgage payments.

At 30%, that's 54,000 pesos per month available for your mortgage. At a refinance rate of 5.99% on a 20-year term, a monthly payment of 54,000 pesos supports a loan balance of roughly 7,500,000 pesos. That's meaningful borrowing capacity for most Philippine homeowners.

Which Banks Are More Flexible With Commission Income?

Among the major Philippine banks, there is meaningful variation in how they treat commission-based borrowers. Some institutions have more structured guidelines that make commission income difficult to use fully; others take a more holistic view of the borrower's financial picture.

Generally speaking, universal and commercial banks like BPI, Security Bank, and Metrobank have experienced underwriters who regularly handle non-standard income situations. Pag-IBIG (HDMF) has its own income assessment methodology that can be favorable for commission earners who are Pag-IBIG members with consistent contribution records.

Rather than approaching banks individually — each with their own application process, timeline, and requirements — working with a mortgage broker allows you to submit once and have your profile evaluated across multiple lenders simultaneously. This saves time and increases the likelihood of finding the most favorable terms for your specific income structure.

Real Example: A Sales Manager's Refinancing Journey

Consider a pharmaceutical sales manager in Quezon City with a home loan of 4,200,000 pesos at 8.5% per annum, taken out in 2019. Monthly payments were approximately 36,500 pesos. Her income consists of a base salary of 45,000 pesos per month plus quarterly performance bonuses and monthly commissions that average 130,000 pesos — giving total average monthly income of around 175,000 pesos.

After refinancing to 5.99% through Nook, her monthly payment dropped to approximately 30,100 pesos on the same loan balance and remaining term. That's a saving of around 6,400 pesos every month — or 76,800 pesos per year. Over five years, that's over 384,000 pesos kept in her pocket rather than paid to the bank in excess interest.

The key to her successful application: two years of ITRs consistent with her declared income, 12 months of bank statements clearly showing commission deposits, a Certificate of Employment specifying average commissions, and commission vouchers for the past year organized into a single PDF.

Common Pitfalls to Avoid

• Underdeclaring income for tax purposes: If your ITR shows 60,000 pesos monthly but you're claiming 200,000 pesos to the bank, you will not get approved. Tax compliance and loan eligibility are directly linked.
• Submitting inconsistent documents: The figures in your bank statements, ITR, and commission vouchers should tell a coherent story. Discrepancies raise red flags for underwriters.
• Applying during a low-income month: Because banks often look at recent statements, try to initiate your application after a strong commission period rather than at the end of a slow quarter.
• Neglecting your credit score: Commission income or not, your credit history matters. Clear any overdue balances on credit cards or existing loans before applying.
• Going it alone across multiple banks: Each bank application triggers a credit inquiry. Multiple inquiries in a short period can negatively affect your credit score. A broker submits on your behalf more strategically.

Commission Income vs. Self-Employment: An Important Distinction

It's worth clarifying that commission-based sales professionals who work under an employer are treated differently from fully self-employed individuals. If you receive a payslip — even if most of your income comes from commissions — banks categorize you as employed, which generally means a simpler documentation process and more favorable underwriting treatment.

If you operate as an independent contractor, sole proprietor, or registered professional without an employment relationship, you'll follow a similar but somewhat different path. Our guide on self-employed home loan refinancing in the Philippines covers that scenario in detail, including the specific ITR forms and financial statements required.

Getting Started: The Practical Steps

Here is a clear sequence to follow if you're a commission-based earner ready to explore refinancing:

• Step 1 — Check your current rate: Pull out your latest loan statement or call your bank. Know your current interest rate, outstanding balance, and remaining term.
• Step 2 — Gather two years of ITRs: If these aren't filed or don't reflect your real income, speak with an accountant before proceeding. Amending past returns is possible and sometimes worthwhile.
• Step 3 — Compile 12 months of bank statements: From the account where commissions are deposited.
• Step 4 — Request documentation from your employer or principal: Certificate of Employment with commission details, or principal relationship letter.
• Step 5 — Organize commission vouchers: Last 12 months, sorted chronologically.
• Step 6 — Submit through Nook: Nook is a 100% free service for borrowers. You upload your documents once, and Nook identifies the best available rates across Philippine banks for your profile.

The entire process, when documents are complete, typically takes 4 to 8 weeks from application to loan release. Nook guides you through each stage, liaises with the bank on your behalf, and helps you understand each offer so you can make the most informed decision.

If you're curious whether your debt-to-income ratio might be a concern given variable commission income, it's also worth reading about refinancing options for borrowers with higher debt ratios — that guide covers how banks assess affordability when income is less predictable.

Commission-based income is not a barrier to refinancing. With the right preparation and the right partner, you can access the same low rates available to any salaried borrower — and put thousands of pesos back into your pocket every single month.
