Complete Beginner in Real Estate Investing

[Corazon B.]

Hi,

I have never invested on a property before and I would like to get in the game just for passive income because I think it might be good for long term wealth/retirement. 
Next year, I am planning to invest on a property, and I believe I will be able to purchase a condo on which I will use to rent out. Currently, I have 70k in my savings and next year I should have enough money($120k) to pay cash for the condo. But what I am scared about is not purchasing the right condo at the right price and at the right location. And paying thousands of dollars on a property is daunting especially if I am not that knowledgeable in real estate. I read a few books and spoke to a few people yet I am still not that confident. How exactly do I know if the condo that I will purchase is a good deal? How do I know if what I am buying is at the right location and at the right price? I live in Fort Myers, Florida. Does right location mean there is low crime rate, no flood zone, and low unemployment rate? Does right price mean I must know what is the average per sq ft for houses in Florida and do my calculation on condos being sold making sure I get the best deal? Also, are condos better for rentals than single family homes? 

Any tips/advice would help.
