What is the ruling on purchasing a real estate unit that includes an annual maintenance deposit, knowing that there is no information about how this deposit is invested, nor is it possible to object to its investment method, and there are no other real estate alternatives that do not include this system?

We have clarified that there is no objection to purchasing a property with a condition for a maintenance deposit, whether it be a portion of the price or separate from it, and even if it is mandated by the state and will be deposited in a usurious bank. The sin in that case falls upon the one who deposits it there, not on the buyer. This is similar to commercial insurance mandated by the state.
