How to Maximize Cash-Flow and Reduce Expenses!?

[Brett Robinson]

Hey BP Community.

I have been in the RE game for around 5 years and it's going really well.
I own 5 properties that equal 9 units now that I rent out furnished and usually shorter term (1-4 months).

I manage the places myself and charge pretty high rents since its shorter term and furnished.

I pay for all utilities, and wifi etc. 
I am looking for ways to maximize my cashflow by reducing my expenses.

Curious for suggestions that make a difference!  Thank you for your time and suggestions :)
