Owning a vacation home or cottage can be the perfect weekend escape from a hectic work week and provide countless memories for your friends and family. If the cottage has year round access, and is fully winterized with a permanent heat source, then it can be purchase with as little as 5% down payment. If the cottage does not fit these requirements, but has a kitchen, 3 piece bathrooms, bedroom and a common area, then a minimum 10% down payment will be required. Qualifying criteria for a cottage mortgage can vary depending on the property and its location.
