People resident in India may borrow, both in rupees or foreign currency; but conditions apply. In case of borrowing in INR from NRIs/PIOs, these terms and conditions need to be complied with...
* Borrowing shall be only on a non-repatriation basis.
* The amount of loan should be received either by inward remittance from outside India or by debit to the NRE/NRO/FCNR(B)/NRNR/NRSR account of the lender, maintained with an authorized dealer/bank in India.
* The period of loan shall not exceed three years.
* The rate of interest on the loan shall not be more than 2% above the bank rate prevailing on the date of taking the loan.
* The payment of interest and repayment of principal shall be made only to the NRO account of the lender.
The terms and conditions are prescribed under the Foreign Exchange Management (Borrowing and Lending) Regulations, 2018, for borrowing in foreign currency from NRIs/PIOs. However, a loan from a foreign national in favour of an Indian citizen under the automatic route may not be possible.
Since there are restrictions to lend as mentioned above, you may better lend the amount through your close relatives under a mortgage loan which will be very safe especially if he fails to return the amount, his property can be brought to sale and money can be recovered.
