SIP vs buying house(BLR edition)

When we started living in Bangalore in 2015, we were living in Bellandur. 3 years later when we wanted to change our rented house, we had to move to Harlur road. At that time, Harlur road felt like really far but we had to move because the rates and availability were making Harlur road infeasible. Post pandemic when I moved back to Bangalore, it was really painful to find a decent rented place. I had to move houses 2-3 times in a year. Paid 75K in brokerage and the same amount in painting charges. Plus loss of time and random policies from people. Finally I bought a home on Sarjapur Road and I couldn’t be happier. My dad used to ask me to buy a house since forever and I could easily afford one since 2019 but I wanted to put money in SIP. If I would have bought a house on Harlur road that time, I wouldn’t have been pushed to Sarjapur Road. If I would have not bought a house even now, I would have been pushed even further in 2-3 years. Now I can move out to India and even come back in the craziest of bull markets knowing that I can get a place in 30 days notice. Now you tell me which financial model can incorporate all of these variables. My checklist for house buying would be: 1. If you know that you will be working for a foreseeable future and not going for a PHD, masters or starting your own thing. 2. You have a mid size corpus. A bit of backing from your family doesn’t hurt. 3. If you can comfortably pay the EMI for a 15-20 year loan period. 4. You’re older than 26-27 and you have stayed in Bangalore for 2-3 years.
