Apart from the applicant's financial standing, employment, and mortgage situation, the age and location of the subdivided unit are important factors to consider. If the property is in an older building, the applicant should be aware of its age, as the loan-to-value ratio for the subdivided unit mortgage may decrease with the building's age. Generally, banks calculate the maximum mortgage term by subtracting the building's age from 80, such as 80 minus 55, resulting in 25. In this case, the longest mortgage term available would be 25 years.
