How to analyzing rental deals without a pro account
Good afternoon all,
What is a good resource or formula to use to analyze rental deals? I know the best way to analyze deals would be to upgrade to a Pro account but that is not feasible for me right now. I would like to get some practice at work while we are slow. Is there a website with a formula that I could use? Also, what are the most important numbers to use? I know rent price, insurance, utility, taxes; anything else? Thank you guys for your time and sorry about all the questions.
