Is there any obligation to take down your mezuzot if a house you own (and live in some of the time) is rented to Gentiles for an extended period of time (e.g. over 30 days)?
I ask because I recently heard someone doing so, and they were under the impression that this was halachically required, but I have never before heard of this being done. And if this is not required, are there sources who suggest doing such as a best practice, or a chumrah?
