Steer clear of older MFH??
Comparing a duplex from 1940 and 2003:
Neither requires immediate rehab.
The older duplex cash flows $550/month (30% ROI all things considered) and the newer one $350/month (14% ROI).
The older one has window a/c units. The newer one has central air. Both in the same town.
What would you prefer and why?
