Dominic Wu writes, builds, and maintains everything published on Mortgage Ledger — every calculator, every guide, every glossary entry, and every policy page on this site.
Name
“Dominic Wu” is a pen name, and this site says so plainly rather than implying otherwise. It is used consistently across all content here, and it refers to one real, identifiable person who is contactable at pacificledgerstudio@gmail.com and who is personally accountable for what appears under it. It is not a shared house byline, an AI-generated persona, or a fabricated expert. Readers who need to reach the person behind the byline can do so at the address above.
Background
Dominic Wu’s working background is in corporate real estate operations — the administrative and financial side of commercial property: leases, property financing structures, and the amortization models that sit underneath them. Mortgage Ledger grew out of that work. Running amortization schedules for commercial debt is a habit that transfers directly to residential mortgages, where the arithmetic is the same and the stakes for the individual borrower are considerably higher.
Areas of experience
- Amortization mechanics: payment derivation, interest allocation, principal curves, and how extra principal changes a schedule.
- Loan-cost modelling: total interest, breakeven analysis, refinance and recast comparisons, and the sensitivity of those results to their inputs.
- Reading and reconciling loan disclosures against the underlying math — APR versus note rate, financed costs, and what a term reset actually does to lifetime interest.
- Translating the rules that govern consumer mortgages — the Homeowners Protection Act, TRID disclosures, RESPA escrow limits, mortgage-insurance duration — from the source documents into plain language.
Limitations of expertise
Dominic Wu is not a licensed mortgage loan originator, mortgage broker, real estate agent, attorney, CPA, enrolled agent, CFP professional, or registered investment adviser, and holds no professional license or credential in lending, law, accounting, tax, or financial planning.
He is not qualified to, and does not, advise on whether you should take a particular loan, refinance, buy or rent, or how much house you can afford; interpret your Loan Estimate, Closing Disclosure, or loan agreement; assess your creditworthiness or underwriting eligibility; recommend or rank lenders; or give tax, legal, or investment advice. Nothing published on Mortgage Ledger is personalized advice, and reading it creates no professional–client, lender–borrower, or fiduciary relationship.
Where a question turns on your specific circumstances, the honest answer from this site will always be to take it to a licensed professional who can see your full picture.
