Buying a house in gurgaon !!

Hi guys I come from a small town in Punjab. Recently relocated to gurgaon from Pune working in IT and have been searching for house to buy. I come from a decent family background where earning 1 lakh a month was considered achievement. Now coming to gurgaon I have been searching for a house to buy but seeing the prices(which I feel very much overpriced, I am saying coz I have lived in Pune Chandigarh) I still feel very poor in terms of bank balance like for a decent flat they ask anything b/w 1.5 cr to upto 4 cr

Now considering a scenario where if some bank even agrees to give me loan on property value of say 2.5 cr plus gst plus renovation plus society charges, it would come around 3 cr and on a loan of 2.5 cr emi is around 2.2lkh a month for 20 years So my question is to the folks who made it to buy a house in ggn how did you managed it? Was it paternal wealth or some other side hustle or what made you achieve it or maybe any suggestions you have I currently earn 2.3 lkh/mnth n my wife 80k/mnth. We still feel it is unrealistic to take a loan of 2.5 cr with emi lasting 20 yrs. Plus we have to give some black money as well by converting our white money to black
