What's the best thing to do to a relative who lends you money but puts 5% interest every month? :(

If I were him I would pay what I owe and refuse to pay anything else. I would add up all the payments and work out if I had paid off the debt by now.

Obviously your dad wants to do the 'right' thing, but at what cost to him and all of you? Unless there is legal documentation that your dad signed whereby your dad could be sued for non-payment what is the relative gonna do? Send the goon squad? Screw that.

Then I would cut off contact completely. To me they would cease to be family.

You should apply for your own student loans, 60 percent APR is nothing less than debt slavery..

you should tell your father not to borrow anymore money from this person.. get a part time job and help pay it back..
And don't forget to say thank you to him for doing this..

That’s very extreme

5% every month? That's 60% a year if we don't count compound interest. That's insane.

Have them arrested for loansharking

Only an asshole lends momey to a family member at 5% interest.

Dont take a loan from them.
