We would highly recommend her services to others.
She and her team is immensely knowledgeable, highly experienced, very professional and proactive. She is easily reachable and very prompt in her service.
Fortunately, a trusted friend recommended Tanuja Sinha to us. We were extremely impressed with her services. During our approximately two-hour meeting, Tanuja provided a comprehensive explanation of the entire selling process, and I subsequently signed the necessary paperwork. From that point onward, Tanuja efficiently managed all aspects of the transaction, including obtaining a PAN card, completing the mutation process, handling tax payments, and setting up a bank account. Her attention to detail was truly remarkable.
Tanuja also connected us with a highly competent real estate agent, who proved instrumental in securing a sale at a price that exceeded the market value by ten percent for a comparable flat.
The service we received from Tanuja exceeded our expectations. The entire experience was stress-free, and working with Tanuja was a pleasure. I wholeheartedly recommend Tanuja without any reservations.
