Questions Clients Ask
Short answers.
Who handles my application?
Thomas himself and his immediate associate team. One point of contact from first call to settlement and beyond.
Why "Smooth is fast"?
Careful preparation up front beats speed of typing: files are compared across thousands of lending options, which is why 96% get approved on first submission.
What happens after settlement?
Lifetime service: personal finance reviews every six months to keep the rate below market average and grow the property profile.
What is Thomas good at?
Commercial and development lending (No.1 settlement volume in Australia), investment portfolios, SMSF structures, and first-home buyers who want the paperwork done once.
Do brokers charge a fee?
Many brokers are compensated by lenders, so borrower cost is low or nil. Confirm the structure upfront — we do.
Broker or go direct to a bank?
A broker compares across lenders rather than one bank's shelf, and negotiates on your behalf through to settlement.
Want to join the industry?
Thomas has coached more than 25 successful mortgage brokers since 2015 — reach out if you want a mentor and a partner.
