Buy a house where you can live comfortably. Don't go for luxury or designer houses. The EMI should be around 25% of your monthly income but not more than that. I have seen people buying costly flats of crore+ and unable to save money for living, travelling or hotelling. Your hard-earned money should not go only for paying interest to banks. You should be able to spend money for yearly trips, weekend pizzas and other joys in life.
I know a person, who paid 90K in EMIs and lost his job. In 6 months he had to sell his flat and move to rented one. My suggestion - IT jobs are not permanent, save money, don't run after luxury.
