Non-Resident Indians (NRIs) in the USA can legally rent out their property in India. The primary method involves granting a Power of Attorney (POA) to a trusted family member, friend, or relative in India. This POA allows the appointed attorney to execute rental and leave & license agreements on your behalf. It's advisable to get the POA attested abroad and validated in India. For added convenience, consider using professional legal services and exploring online platforms for digital execution of agreements, which can be signed electronically.
