I’m planning to buy a pre-owned apartment for around ₹90 lakhs. The owner wants ₹20 lakhs in cash and the remaining ₹70 lakhs documented legally. I’m a regular salaried person and it’s tricky to manage such a large cash payment. I have the funds in my bank account, but I can’t withdraw such a huge sum at once. I also plan to sell my current flat for ₹65 lakhs. What’s the best way to proceed with this purchase, keeping in mind the cash component? Any advice would be greatly appreciated.
