Yes. I am also an NRI and I sold my paternal property six months ago. S2NRI.com helped me a lot in finding the suitable buyer of my property at Lajpat Nagar in New Delhi. I dropped an email to this portal. But on getting no instant response, I called on the number which is mentioned on the website. Lastly, I interacted with one of the staff members of S2NRI in Mumbai. We had later chat on skype about how to make the property deal. I got the money in Indian currency but was satisfied as it handled the entire deal by self. I got more amount that that of my expectations.
You too can go through that portal.
