What to know about a mortgage in Downtown St. Catharines
Many homes in Downtown St. Catharines are condos. Lenders include your monthly condo fees when they work out what you can afford, and your lawyer will review the building’s status certificate, which shows the reserve fund and any upcoming special assessments.
If you’re buying new construction in Downtown St. Catharines, plan for builder deposits paid in stages and closing dates that can move. Your mortgage approval needs to be ready, or renewable, for the actual closing date, and the final price can include adjustments you won’t see in the purchase price.
Older homes in Downtown St. Catharines often need updates. A thorough inspection helps you budget, and if you plan to renovate, ask about a purchase-plus-improvements mortgage, which adds the cost of the work to your mortgage up front.
