Question 5: Is your chosen property affordable for you?
Just as important as capital is the question of affordability. This determines whether or not you can afford your property in the long term.
The following rule of thumb applies: the costs for your property should not exceed one third of your gross income. Property costs consist of interest, mandatory amortization and the property’s running costs (maintenance, repairs, etc).
When deciding whether a property is affordable for you in the long term, lenders don’t use effective interest, but rather a higher imputed rate of interest, currently at around 5 percent. This should ensure that customers will be able to afford the property even if interest rates go up.
Therefore, the affordability calculation is:
5 percent of the mortgage amount + mandatory amortization (repayments) + running costs at percent of the property’s purchase price (running costs) ≤ one third of gross income
