The calculation of affordability is used by the lending financial institution as security before granting a mortgage. Affordability is expressed as a percentage and provides information on the ratio of current financing costs to the gross income of the mortgage borrower. The resulting costs should not exceed one third of the gross income, otherwise the lender will be unlikely to approve the financing project. There are, however, providers who will accept higher affordability values in individual cases. In addition, very good affordability values can result in a discount on the mortgage rates. Financing costs include interest and amortization payments as well as maintenance costs.
To calculate the interest costs, the bank uses an imputed interest rate of usually 5%. This interest rate is intentionally set at a high level to ensure that the customer is able to meet his or her payment obligations even if interest rates should rise. The amortization period is usually set to 15 years for the calculation, but there are also providers who use a different duration for the calculation. Side costs include expenses for water and electricity, insurance costs and possible repair work expenses - these costs are combined in the affordability calculation and are measured at one percent of the value of the property.
Banks consider a number of different factors when calculating the income of a potential mortgage borrower. Bonus payments, for example, i.e. income that is not guaranteed in the long-term, may be considered in a different way depending on the provider. Another factor is the professional situation of the borrower: how good are the chances of finding a new job with an equivalent salary if the job is lost? In the case of young couples, it is also the case that banks "imply" a desire to have children, which would temporarily reduce the total income of the couple. With this theoretical assumption, it often does not matter whether a child is actually planned.
