Sorry for the “tough love”, but if you don’t immediately investigate them and take appropriate action, you may not be cut out for managing rentals. 

Looking for advice on payment collection/managment software.

House hacking will also give you some personal "property management" experience.

I do not want spend my W2 income to cover house mortgages, to not have pressure if things like layoffs will happen, so my plan is to buy house in a good neighborhood that may have appreciation and some minimal cash flow after all expenses (management, maintenance and vacation).

I live in the Seattle area, but I work with a team on the ground that helps me locate deals, project manage rehab and provides property management.

I managed to get 1 8 unit and 1 6 unit building over the last few months and have done well with them.

Hi RyanFind a reliable property manager for accurate rent rates to determine how the numbers will work.

Airbnb management?

If you just want to invest and not become a syndicator one day you might want to seek out a group that solely focuses on investing/management.

As the title says, I'm looking for your guy's recommendation on the best software to use in order to collect rent and manage rentals.
