An NRI or Person of Indian Origin (PIO) can own both residential as well as commercial properties in India and there is no restriction on the number of properties you can buy. However, you cannot purchase any agricultural land, farm house and plantation property. You can have ownership of such property only if they've been gifted or inherited.
Also, the monetary transaction must be in Indian rupees (INR) and through normal banking channels using an NRI account.
Funding the Purchase:
Lenders will be more than happy to fund your purchase provided you are eligible and the property papers are clean. It will be wise to get the papers verified by a lawyer before going ahead. Make sure to check the title papers of the property, especially if it is inherited or jointly held, and take a bank release in case it was at any point of time under mortgage. Also, take a no dues certificate from the seller at the time of purchase to ensure there is no water, electricity or any other pending bills with the authorities. For new constructions, land title should be clear and the builder should have taken all approvals and permits from the civic authorities in terms of construction. Also, education qualification and profession play a role in deciding your loan eligibility. Like, only graduate NRIs can avail home loans in India.
