The Perfect Apartment Unit Mix

The most common apartment investor request is for a building with a predominance of two bedroom units. Don't show them a building of 1 bedrooms and, the horror, a building of studios. I'm going to step out on a limb here - I love studios and 1's. One bedrooms tend to have overall low occupancies. This is important when the landlord pays for water, garbage, etc. Realistically less toilet flushes (ok, sorry, but true) which means less plumber calls and lower utility bills. Studios are even more so this way. If I was in need of crashing at a friends apartment, I would choose the friend with the most ample space. Reasonable? Or I could definitely be swayed by location.... sure. Something to think about.
