«طَمَعَنْجِي بَنَى لُهْ بِيتْ فَلَسَنْجِي سِكِنْ لُهْ فِيهْ»

A grasping man puts up a house hoping for rent, but the person who moves in has no money at all. The building is occupied yet earns nothing, and the expected income never comes. Both figures are named for their character and circumstances, not for any trade.

The saying targets someone whose greed is extreme and who meets a turn of events that wipes out what he hoped to gain. It presents the loss as a fitting result: profit was the whole plan, and the plan ran straight into an empty pocket. The scorn falls on the greedy builder, not the penniless tenant.

Say it, with some irony, when someone eager for profit invests in a venture and the only tenant, buyer, or borrower turns out to have nothing to pay. The ridicule falls on the greedy party, not on the poor one.
