There's nothing wrong a slab foundation in fact they are more energy efficient typically.

We've never had a rental property before, but we are handy and I do have some time/energy to put into such a thing.We have a house in the Boston metro area that's worth around $900k.

The efficiency of a solar installation is dependent on many factors - location (or average daily sun hours), house orientation (15deg SSE ideally), roof inclination, shade obstructions (on the roof and/or around the house), consumption, components used, inverter or microinverters, hail resistance, warranty, utility payback vs net metering.
