Loan tenures are about 25 years, so most families take a home and pay the loans during their active service life.
About 10 or 15 years down the line, one or two floors are added to tge house, for rental purpose. Here too, rental is less than half of construction cost. Again, intent is for very long term appreciation of the asset, rather than a passive income source.

Edit 2: An 1800 sft, duplex house, built in a 150 square yard property, cost about Rs. 13 million. And that is in a city like Hyderabad. Costs about double that in Bangalore, the top IT city in India and probably more in a city like Mumbai & New Delhi.
An average salary of an IT employee, with about 10 years of experience is about Rs. 3 million per year. Banks give a loan of about Rs. 10 million on that house, and employees usually source the remaining amount from further loans or high interest borrowings. Cumulatively, with current interest rates (have been stable for a decade now), EMI on a 13 million loan is about 0.13 million per month, meaning more than half of an employees salary, 1.56 million, goes to EMI payments.
Average rental value for that property is about Rs. 25000 per month, or Rs. 0.3 million per year. So hardly enough for covering EMI. Tenure on the loan is usually 20 to 30 years.
So, for most families, with wife and husband working, owning one house is within reach, but two is beyond capacity. With so much of income going to EMI, most choose to stay in the house rather than rent it out.
As it turns out, this is not the case:

FTSE100 appears to have doubled in 20 years, my house in a poor UK city has quadrupled in value. Starting wages have increased by about 70%.
Another reason is lack teeth in laws that implement rental agreements. In fact, most owners hardly take any rental agreements or leases.
This must be great for people who like to move around a lot.
