Corey every buyer I have worked with including some condo/townhome buyers ALL want a usable garage. It is my opinion that taking away your garage could impact the value of your home should you try to sell it. If you decide to proceed with the conversion, try doing something that could easily be converted back. I have friends who put down indoor/outdoor carpet, ran a heat duct for heat, put up a simple wall using about 1/4 of a bay to enclose the furnace, water heater and other garage stuff and this created a HUGE recroom in the other 2.5 bays for the kids, but can be converted back easily at anytime. I think they might have let the kids paint something really wild too, which only needs fresh paint to return to original garage walls.
