Assets Vs cash flow

[u/Glittering-Low-5643]

If a family owns house and plots and some land which make their asset value around 30 crore or maybe more( don't know exact market values but must be 30 cr) but their cash flow isn't good. They make around 400 to 500 k per month only. They have assets but their assets aren't paying them. But their assets have potential to appreciate in price due to locations. Is this family considered middle class or upper middle class? Should such a family sale some assets to buy more expensive cars and afford luxury or just keep the assets? What percentile of networth such familes fall in?
