adding garage to duplex for flip

[Bruce Runn]

Just bought a duplex to renovate in Uptown in Minneapolis (Hip area) and it doesn't have a garage.  Since most duplexes are bought by investors, is it worth the $15,000 to put in a 2 car garage?  I get it makes it more marketable but really only  adds  $50/stall to rent/income.   Thoughts?

My bids were $18,000 and $20,000 from garage builders to my specs.  I ran the numbers with my carpenters who do my renovations and with me being the General Contractor, pulling permits, buying all materials, subbing out concrete and electrical, the cost would be about $12,000 or $27/sq ft instead of approx. $40 -45 sq ft.   I don't put a price on my time/overhead/profit as a garage contractor has to but essentially the price for that looks to be about $6-8,000.  A builders overhead is real so I assume that's about 10% which makes the margin/profit a minimum of $4,000/garage.   As I'm working on two more possible purchases right now, it's up in the air whether the garage will happen in Spring/summer based on my schedule since its more of a nice to have versus a need.
