Attics & Basements in 1900-built duplexes

[Tom Henderson]

I'm currently purchasing my 4th rental property in Minneapolis. It is 2 bed-1 bath up/down. I'm curious how many of your duplex investors have built out the upper unit's attic? It would probably cost between 12-15K (lots of sweat equity after framing, electrical, plumbing work). 

Would you rather use your capital to build out and maximize your investment, or continue purchasing other investments (go horizontal with more properties), and then in the future, enhance your portfolio by building new bedrooms in basements and attics?

Thanks!

Tom
