Context - Buying as an investment, don't plan to live there. I plan to live on rent. Current rent is 17k/month.
I'll keep it short for max input. I'm looking at some flats priced around 60-70L for a 2BHK. Rent in the area will be ~30k. If I pay 20L down and take a home loan for 40L, EMI will be approx ~65k for a period of 7 years (I want to pay it off ASAP, to pay the least amount of interest).
I earn around 1.5L per month. Personal expenses are ~50k per month. Assuming I get 30K as rent I'll have to pay a maximum of 40K as emi. This is a very recent thought on which I've just researched for a couple of hours so apologies if I missed anything important but honestly this looks quite doable to me.
