And the split is whatever you decide on. 50/50 is what a lot of people usually do.

Let your criteria do the filtering for you.Regarding retention and renewals, the only time I have asked people to leave is when they have had rent payment issues and/or damaged the property. 

Most people assume that house hacking means living in a 2 bedroom 1 bath duplex.

There are also horror stories about people loosing their property in Spain. 

Then I work with a local insurance broker give them a valuation of the property, explain that the property is being rented and by how many people.

One fire they had lit under and under pass and weakened it and it failed :)  Also they burn up their RVs and campers pretty often then the basic tent fire...

Every tax season, I see people unintentionally overpaying the IRS.

Your goal is to build a passive real estate portfolio (we can discuss what passive means to you), so while I don't condone throwing $100k into a deal without even a basic understanding, alternatively doing so will teach you far more lessons than reading a book will.  

@Jason Sinclair, having a designer for a wife, I would answer that it really depends heavily on each house, the flow and usability of the spaces as they are, and the overall use of space in the house as a whole.That being said, while there may be a small shift towards more separated spaces, "open concept" is by no means dead, and in many markets, most people seem to still want to have connectivity between their communal spaces.In fact, my wife's current flip is a split level (although technically it is a split-foyer), and she is taking out a structural wall to connect the kitchen, dining and living areas.  

So thanks for contributing because you have helped more people than you know!
