I prefer assets that make me a high return for the lowest amount of work possible (semi-passive involvement). And assets that pay me in several unique ways. Cash flow is only one way RE makes money for me. I also get principal reductions, appreciation, tax advantages (depreciation), and I control the rental increases on a yearly basis. Plus a majority of the capital is provided by the secondary market on 30 year fixed low interest rate debt.
The particular strength of this sub-sector is in precision cutting, polishing and processing small diamonds (below one carat). India is also a hub for processing of larger diamonds, pearls and other precious stones. Statistically, 11 out of 12 diamonds set in any jewellery in the world are cut and polished in India. It is also a major hub of gold and other precious-metal-based jewellery. Domestic demand for gold and jewellery products is another driver of India's GDP.
For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
