A 3/2 with a detached apartment behind it?

[Matthew Patton]

Hey all,

As I hunt for my first multiplex, I'm coming across 3/2 SFHs with either one or two apartments in a detached building behind it. I'm curious for anyone out with one of these setups. At first glance, it would seem like someone interested in a full size single family home isn't interested in having people live on the same property behind their house and it may prove harder to rent out than the apartments themselves. Or at least, that's my guess. Or am I wrong? I keep coming across a 3/2 SFH with a detached 2 car garage and a 2/1 above it.

The numbers work for me. But I'm concerned about rentability with the front/main house after I move out of it in a year. 

Thanks again!
