PITH Explained: What Lenders Really Look At in St. Albert
Buyers tend to fixate on the mortgage payment. Lenders look at a bigger number — PITH — and understanding it keeps you from overreaching.
What PITH Stands For
When a lender in St. Albert, Edmonton, or Sturgeon County decides how much you can borrow, they don't just look at your mortgage payment. They look at PITH:
- Principal — the part of each payment that pays down what you borrowed.
- Interest — what the lender charges you to borrow, set by your rate.
- Taxes — municipal property taxes, which vary meaningfully between the City of St. Albert, the City of Edmonton, and rural Sturgeon County.
- Heating — the estimated cost to heat the home, which matters in an Alberta winter and which lenders include as a set estimate.
Add those four together and you get your real monthly cost of carrying the home — not just the piece you send to the bank.
Why Lenders Use It
PITH feeds into the ratios lenders use to decide whether a mortgage is safe to give you. The main one is the Gross Debt Service (GDS) ratio — the share of your gross income that goes to housing. Add other debts and you get the Total Debt Service (TDS) ratio.
Lenders set limits on these ratios so borrowers don't take on more than they can carry. The exact thresholds shift with lending rules and your specific situation, so your mortgage broker is the right person to tell you where you actually stand. The point for you as a buyer is simpler: the bank is measuring the whole cost of the home, and so should you.
Why It Hits Differently Depending on Where You Buy
Two homes at the same price can carry very differently once you fold in PITH:
- Property taxes vary by municipality. St. Albert, Edmonton, and Sturgeon County each set their own rates. A home in one can carry a noticeably different tax bill than a similar home in another.
- Heating depends on the home. An older, draftier house costs more to heat than a newer, well-insulated one. Over a year, that difference is real money — and it's baked into the lender's math.
This is exactly why I tell buyers not to shop on list price alone. The cheaper house isn't always the cheaper house once the taxes and heating are in.
Beyond PITH
PITH is the lender's framework, but your actual budget should also include:
- Condo fees, if you're buying a condo
- Home insurance
- Maintenance and repairs — always budget for these
- Other utilities — electricity, water, internet
None of those are in PITH, but all of them come out of the same paycheque.
How to Use This
Before you fall for a listing, get pre-approved and ask your mortgage broker to walk you through your PITH-based numbers for the kind of home and area you're considering. Then I can help you shop within a range that's genuinely comfortable — not just one you technically qualify for. Those are two different numbers, and the gap between them is where a lot of buyer stress lives.
A Word on Advice
I can help you understand PITH and factor local taxes and heating into your search. For your actual qualification, ratios, and borrowing limit, rely on your mortgage broker — those numbers are theirs to run for your specific situation.
