Should I by a shop adjacent to my SFR?

[Morgan Reinart]

I just received an email update from a local realtor with a ~20'x30' shop with alley access listed for $30,000. This shop is located directly behind a single family rental that I own. It's insulated, has electricity, and a loft. 

My gut reaction was to look into the property to add value to my rental. The future could be one of two routes for this property. 

1. I continue to rent the house and I could rent the shop out as well. 

2. I've thrown around the idea of selling the property later this year or next year (1031 exchange) to pursue a small multifamily. 

Any suggestions?
