@hallie4 I was in a very similar situation. Working from home and renting a big house. The land lady wanted to sell it for 2.5 cr, which was beyond my budget at the time. I took the plunge and never been happier. Sure, first year is difficult. You have much much better financials than i had at the time.
While taking a home loan, do dm me, or check out BOB's home loan advantage savings account. And bring the interest rate down till 8.5. Trust me, they will come low. Still 1.5 cr home loan pending for me, but things are better now.
What area in Delhi are you looking at? I used to stay in GK2 and absolutely loved south delhi.
