Home to live in - SFH or Duplex

[Douglas Slingerland]

Hello,

I am looking at purchasing my first primary residence.  I am faced with two options.

1. Purchase a nice SFH nearby work and the kids school. Enjoy privacy, peace of mind.

2. Purchase a duplex (no quads in the area), have half the mortgage paid by tenant.

The pros and cons of each should be apparent.  It's really physical comfort vs. financial comfort as far as I can see.  Can anyone make any stellar arguments for either option?
