How to evaluate a rental property

[Raymond Ali]

How do you determine if a rental property is worth purchasing or not?

I understand that the 50% rule is a guideline for analyzing rental properties but what if the properties expenses are taking 80%-90% of the annual income? is that normal?

for example if a property's annual income is $45,000

and the annual expenses are $39,600,

thats nearly 90% of the income going towards expenses.

would this be a potential investment?
