its all about cash flow money in and money out monthly
think about how much the real cost of owning the property maintance fees, taxes,one month without rent till you get your first tenant,think about managing the place if u live away or abroad paying someone to collect your rent and thats another month of rent gone,think about insurance,think about repairs every 3 years on the other side you have rent coming in if there are ppl willling to rent your property take away from the rent the profit you give to the bank intrest rate take away depreciation of the property
do all the math and you get the real picture
is it worth it??yes if you know what you doing otherwise stay away
and one more thing i forgot your tenant might not pay after few months e.g students
good luck
