Renting out a residential property in an Ahmedabad cooperative housing society on a 5-year leave and license agreement to a proprietary firm requires careful consideration. While a 5-year agreement is possible, it's crucial to first confirm with the housing society committee if commercial use is permitted, as many societies prohibit it. If allowed, ensure the agreement is registered if it exceeds 12 months, and be aware of potential renewal or surrender procedures upon expiry.
