as a car salesman told my DAD in 1964 (I was there at 13) -----when my dad said "" I can pay in cash !!" ----- at the end it is all cash money (yes today the dealership might like avoiding the 3%)
investors use cash --- but so does everyone who uses a WIRE at closing - it is 100% cash to the seller
And the investors CASH is not 100% equity capital (they would be crazy to waste capital that way) --- it is cash as raised by them (investors) from bonds and who knows - maybe even F and F
