Investment properties are generally owned by pension funds, real estate resumes, (listed) real estate funds, real estate holding companies or (private) businessmen. Investment properties are generally rented for 5 to 10 years. Sometimes such investment objects are paid rent-free. Investment properties can be found in shops, offices and smaller industrial halls. Real estate investors have always focused on high returns. Do you want a 10% return every year? The annual net rental income (rental income minus taxes, maintenance costs and interest) must therefore amount to at least 10% of the total purchase value.
