Everyone has a very different opinion and honestly it is whatever your preference and comfort zone.

This comes down to your goals and investment preferences. 

They sometimes have one that they prefer and as long as that title company is reputable...it's all good. 

They do however you prefer you are a "member" as it pertains to Credit Union.

I really prefer a SFH or townhouse.

I've looked into RUBS/sub-metering companies, as my preference would be to have a 3rd party handle the billing for utilities (I heard about this on a BP podcast, and it sounded awesome).  

I recommend minimum 4 coats with poly.  2 seal coats with buffing between and 2 final coats  You can use water base as  well if you prefer, finishing will dry faster allowing for more coats.

What is your preferred investment strategy and why?

@Jin KimAs you can see from the comments above there is no one answer, especially when your own dwelling preferences are involved.
