About
Hi, I'm Pete Diamantakos.
I'm a licensed mortgage agent based in Kelowna, and I help people across British Columbia, Alberta, and Ontario buy, refinance, and renew — with first-time buyers being the work I care about most.

A mortgage is the biggest financial decision most people ever make, and too often it gets handled like a form to be filled. I built Onyx Mortgage to do it differently — to be the agent who actually explains the why, builds a real strategy, shops hard on your behalf, and treats your goal like it matters. Because it does.
Working as a mortgage agent means I'm not tied to any single lender's products. I compare options across a wide network to find the fit for your situation, then handle the paperwork and negotiation so you don't have to. For most standard residential mortgages there's no cost to you — the lender pays the agent — so you get an advocate in your corner without a fee for the privilege.
First-time buyers hold a special place in how I work. There's real help available for people buying their first home, and it's far too easy to leave it on the table simply because no one walked you through it. Finding those advantages, and building a clear plan around them, is what led me to create the Onyx Homeownership Blueprint — a simple way to see your readiness and follow a path to the keys.
How I work
A few things I hold to.
Straight answers, always
No jargon, no upsell, no telling you what you want to hear. If a move doesn't make sense for you, I'll say so — even when it's the one that pays me.
A wide network, not one shelf
A bank can only sell you its own products. I shop a broad network of lenders to find the one that actually fits how you earn and what you're buying.
First-time buyers first
Guiding someone from I don't know where to start to holding the keys is the part of this work I love most. It's where I do my best.
In your corner to the end
From the first conversation to closing day, you get one person who knows your file and keeps it moving. No handoffs, no chasing.
