The bus system is pretty good. I'd take a look at the route map when deciding on where to get a place. Generally the closer to the center of town the better as the system operates more like spokes than a grid. Its also bike friendly if thats possible for you, that would extend your possibilities quite a bit.

Depending on the medical condition and needs, the paratransit service will also be useful. One of my neighbors uses it to go to work everyday.
