Traditional Duplex/Triplex vs. a Converted House Duplex/Triplex

[Matt Gilroy]

Hello BP,

I've been looking at small multi-family investment properties and run into several early 1900's homes that have been converted into duplex/triplex or fourplex rentals.  I'm curios about any downfalls for converted homes.  If it all things were equal, I'd purchase a purpose-built multi-family vs. a converted home.  Am I wrong?  Are there benefits to a converted house?

Cheers,
