The reason why I am saying this is if you do enclose that garage, and turn it into an "Accessory Dwelling Unit" (that's the formal name for them, sometimes called ADU) will you harm or help the value of your home? 

I visited it and also, no disrespect, but it didn't hold up to the "Millennial test"- there was a real lack of bike lanes and easy of transportation. 

do most of the other townhomes similar to yours have enclosed yards? 

Department of Transportation's (USDOT) first-ever Smart City Challenge, Columbus was awarded $50 million in grant funding and leveraged that into $500 million of funding.

Transportation is well organized going to the Downtown and Oakland areas.

All are walkable main streets with good access to public transportation. 

Your commander in chief cut off the keystone pipeline causing a spike in oil leading to increased gas prices, which led to increased costs of transportation for goods. 

It's surrounded by stable & diverse communities with access to major transportation and amenities easily.3.  

@Eric Oszczypala, let me address the problem with bringing in used homes, it often costs way more to transport and set up than to just rehab what you already have and with the issues of affordable housing you could remodel a 40 year old home and still make great money selling or renting, good luck with whatever you do with the home I vote just rehab what you have 

@Ruika Lin This is true that condos do not appreciate at the same rate as SFH or townhouses in Northern Virginia and yes it includes even the ones in great location and access to public transportation.
