I am considering turning an extra space into a short term rental and am considering a Saniflo macerating toilet. 

One thing I heard you say, is that you don’t need to be an agent to access the MLS, but I’m not sure I heard exactly how it is that non agents can access it.

May 1st is still 5 weeks away, you should be able to get the Town in to approve the space (if allowed) before 5/1.

Oakland County has a nice online database you can access at Oakgov.com. 

Some have a clause where they only pay a percentage of CAM for the space they occupy.

This allows you to access home ownership with some of the low down payment options while still furthering your investing goals.

You've accessed the gain through the refinances. 

The thermostat is firmly located in the living space of one unit, which means the second unit would not have control of or access to their heat source.

@Brandon LewisFor investment properties I look for several key indicators- Local businesses/restaurants/shopping centers near by- Easy access to public transportation- Proximity to local schools and the quality of those schools- Investment in the area (is the area being built up/commercialized?)

Now unit sizes that are 5+ will put you in the commercial real estate space.
