Can I buy 4cr house with 1cr post tax income?

Me and my wife both are working at MNCs in bangalore. I earn about 1.1 cr and she earns 60L per annum pre tax. We want to buy a house of worth 3.8cr but with registration and interior, it will go to about 4.25cr. I am really scared to make such a big deal and not sure if I can really afford it. We have a savings of about 3cr combined (60% equity and 40% debt) and are about 28yo. Also, our current expenses stand at about 24L per year. How should we plan this purchase and how do we calculate the budget we can aim for? PS: I am more scared about this purchase as we recently started making this big of a money and come from a very humble background.
