Q: I teach piano lessons in my rented duplex. When I told my landlord about it, he said OK, but insisted that the presence of my students would increase his exposure to lawsuits. So now he's asking me to pay an additional deposit. Can he do that? --Jane C.
A: To answer your question, we'd need to know first whether your state regulates the amount of the security deposit a landlord may require. Many states set a maximum as a multiple of the monthly rent (twice the rent is common).
