I keep hearing bits and pieces about a rental strategy that is best called "Renting to the Disabled by the Room for Above Market Rent" that goes something like this: (1) Buy a house with as many legal bedrooms as you can that still has a decent sized common area, (2) rent it out to the relatively high functioning disabled crowd, (3) via some [unnamed] Government program the State pays above market rents for each of the tenets. (4) Send a house keeper 1-2 times per week to ensure the place stays clean and otherwise make sure there are no issues.The up side is: you get above market rent with a much higher than average tenant count.
