At least that's my current personal opinion/strategy. - John

I personally invest in La Crosse, Wisconsin with a mixture of LTR's and MTR's ranging from single family to small multi-family. 

Unfortunately, common spaces that you use as part of your personal space can't be included in the rental portion calculations. 

I am going to assume that what you mean by "main purchasers" is the majority.Let me finish by saying that I am not a political person, I'm one of the diminishing numbers who believe no politician deserves a flag or a yard sign.

Income taxes vary by person and jurisdiction.

They even in their heart of hearts really want to, and really try, to leave a place "move-in ready" for the next person.

Personally, I'm all in on the location and amenities game for max rental cash flow.

Personally, I prefer the CRM approach (see diagram) since the homeowner communication is critical -- besides, without them, there is no deal.   

It’s crazy that a person who is getting good government assistance doesn’t pay.  

Replicating my experience with “sewer gas” could be a stretch BUT 10 years ago in my apartment building there was a mentally ill person who alway smelled sewer gas when no one else could smell it.
