About Housizz

Built by someone who has seen what happens when homeowners are left without guidance.
My name is Tina Colizza, and I built Housizz because I kept watching the same thing happen.

After ten years as a realtor in Ottawa, I saw homeowners arrive at the selling stage unprepared — not because they were careless, but because nobody had ever helped them think about their home strategically. They’d owned their home for years, maybe decades. They’d invested hundreds of thousands of dollars into it. But they had no clear record of what had been done, no plan for what should have been done, and no idea whether the improvements they’d made had actually added value.

Before real estate, I spent years in construction project management, working with trades and contractors on complex projects. Before that, I worked as a business process analyst for consulting firms — helping organizations find the gaps in how they worked and fix them. I have an MBA. I understand how projects should run, what quality looks like, and what a properly managed asset looks like.

I built Housizz to bring all of that together for you. When you're ready to sell, your Home Property Passport means you arrive at listing day completely prepared — and if it makes sense, I can represent you.

What we believe

Your home is likely the largest financial asset you will ever own. Most homeowners treat it like a place to live — which it is — but not like the investment it also is.

That gap is expensive. When repairs are deferred, costs compound. When improvements are made without a plan, money is wasted on the wrong things. When records are not kept, value is lost at the moment of sale. And when homeowners try to navigate contractors, timelines, and decisions alone — without expertise behind them — the risks are real.

Housizz exists to close that gap. We believe every homeowner deserves the same quality of strategic thinking about their property that investors apply to every asset they own. Not just at the moment of sale. Throughout the entire time you own it.

What Makes Housizz Different

Housizz is not a contractor. We are not a marketplace or a directory. We are your property advisor and project coordinator — the professional layer between you and the complexity of home ownership.

Every project we manage is overseen from scope to completion, with clear pricing agreed before work begins and documented records of everything done.

Every client receives a Home Property Passport — a living record of their property’s condition, improvement history, estimated value, and maintenance records. It builds automatically every time Housizz touches your home.

Every client receives ongoing property intelligence — quarterly value updates, neighbourhood market snapshots, and seasonal maintenance guidance. We are not the right fit for homeowners who want the cheapest option. We are the right fit for homeowners who want the best outcome
