Debt free investors

[David Avila]

I am looking to get advice from any one that started in the rental business debt free. I am saving up to buy property with cash and no partners or investors. 

My questions are:

Was there a benefit to going debt free?

How much money did you start your venture with?

How much should I be prepared to save for costs other than the property itself, such as maintenance and insurance?

Thank you for taking your time to answer.
