The profitability of the usual rent is calculated using the formula:

PROFITABILITY OF USUAL RENT= (TOTAL CAPITAL INVESTED-INCOME-EXPENSES) ×100

For example, if you rent a property in Fuerteventura for 900 euros per month (10,800 euros per year), with annual expenses of 1,800 euros and an acquisition cost of 140,000 euros, the return would be 6.42%.
