Convert basement into ADU or another unit?
My wife and I are currently looking at townhomes in DC. Every house that we're looking at has the zoning code that allows for a second unit. Would it be more beneficial in terms of equity when we go to refinance to put an ADU in the basement, or turn it into a duplex? Most houses that we're looking at are currently 3 bed and 1-1.5 bath with the below grade space allowing for 1 (maybe 2 with a tight squeeze) bedrooms and a bath. Any help is greatly appreciated!
