Taking out a mortgage
I have purchased a 2-room apartment for rent for 110,000 euros and have already paid for it.
Now I would like to take out a mortgage (for renovation and for tax reasons) over 10 years, and then sell the apartment again.
My income (tax class 1) consists of a pension of over 1600 euros net plus 500 euros immediate annuity, with the rent intended to supplement my income.
Is it tax-wise to take out a mortgage of 40,000 euros with 2% repayment or one of 50,000 euros with 1% repayment; each with possible additional repayments.
