Guru talking about buy and hold, renting rooms to gov. agencies for handicapped at 3 X market rents?

[Kevin Romines]

I was listening to a podcast on REI club today about a guru, cant remember his name, but was touting a technique about renting SFR and multi-units by the room to gov. agencies for the handicapped at 3X the market rents?

He paid for all things, utilities, cable, garbage, water sewer, internet, maid service, lawn care.

Has anybody heard of this, or done it? I would like to know more, or determine if its all hype?
