How can we prove that any damage is caused by this specific tenant, given multiple residents in the property?

I also have multiple streams of income and the ability to reduce my expenses sharply if needed to payoff a major unexpected expense.

I'm having a hard time finding any estimating tools for this kind of a project, adding a story and multiple BR/1 BA, and wondered if there were any tools, sites or recommendations any of you have for this kind of a project. 

One of the great things about having multiple residents per property per year is that you can iterate faster than with an LTR.

Mark down all the multis you see by looking for two or more doors in front or multiple air handlers outside or gas meters.

There will be multiple issues unfolding at the same time as there are always something going on!

i would do fha and then go conventional to buy multiple properties.

Best advice I received is think in multiples, fix stuff when it breaks quickly, and first few years probably not going to make any money. 

Now I have a portfolio here of STR's and have helped multiple other out of state and new investors do the same, or reach their goals in whatever strategy they are wanting to move forward with (I started house hacking). 

As far as I know, I don't think software like Stessa or Baselane can really track anything related to multiple owners/partners.
