Questions about this calculator
Which annual taxes does it cover?
IMI every year and AIMI where the property value crosses its threshold, plus the tax on rental income if you let the property out.
What is the monthly reserve for?
Condominium, insurance and maintenance, planned as one monthly figure. Ownership costs arrive irregularly, and the reserve is how they stop being surprises.
Does it include the lease stamp duty?
Yes - the one-off stamp duty on a residential lease enters the plan beside the recurring costs, so the yearly figure is complete.
