When searching for a condo in Calgary, you may come across properties built with post-tension cable (PTC) construction. This building method was commonly used in high-rise, concrete-construction condos during the 1970s and 1980s. While it offers some structural advantages, there are also important considerations to keep in mind when buying a condo in a PTC building.
What Are Post-Tension Cables?
Post-tension cables are steel cables encased in plastic tubing that are stretched under high tension within concrete slabs. This construction technique allows for more open floor plans without the need for support pillars, making for spacious and modern layouts. While primarily found in concrete high-rises, PTC construction can also be present in some wood-frame buildings with concrete slabs above the parkade level.
Potential Risks of Post-Tension Cable Buildings
While PTC buildings offer design benefits, they also come with potential drawbacks, particularly concerning long-term maintenance and financing. Over time, the steel cables inside the concrete can corrode, leading to costly repairs and ongoing monitoring requirements.
Most condo corporations in Calgary that manage PTC buildings have implemented routine inspections to monitor cable conditions. Depending on the building, these inspections may take place every year or every few years, with necessary maintenance costs factored into the condo's operating budget.
Challenges with Financing and Resale
One of the most significant challenges with post-tension cable buildings is obtaining mortgage approval. Many lenders hesitate to approve financing for condos in PTC buildings, and mortgage insurance is typically required regardless of the down payment amount. Among Canada’s three major mortgage insurers, one does not insure PTC buildings at all, while the other two consider them on a case-by-case basis.
Due to the financing restrictions, selling a condo in a PTC building can be more challenging. A smaller pool of eligible buyers often results in lower resale values, which is why many 1970s and 1980s condos in Calgary appear to be great deals at first glance.
Should You Consider a Post-Tension Cable Condo?
Every buyer's situation is unique, and there are advantages to purchasing a condo in a PTC building. If resale value isn’t your primary concern, these condos can offer a lot of space in desirable locations for a lower price. Additionally, many PTC buildings in Calgary are well-managed, with regular monitoring and maintenance plans in place.
Before making a decision, it's essential to weigh the benefits against the potential financing and resale challenges. If you’re unsure whether a PTC building is the right fit for you, consulting with a knowledgeable real estate professional can help you make an informed choice.
