Quote from @Niranjan Sathish: Hello, I am Sathishkumar, have been learning about Real Estate through books and podcasts for the past couple of years. 

Here's a detailed guide on how to screen applicants: Application Screening Guide

I’ve read a couple books but I am always willing to learn… Also if you were 21 , what would you have done differently?

Here's a guide that describes what good cash flow looks like and how to analyze a property.https://www.biggerpockets.com/blog/rental-property-cash-flow...

Read a book, or even a blog like this one:  Application Screening GuideIf the landlord had called the previous landlord (me) they would have immediately denied her."

I suggest listening to the BP podcasts and reading through the blogs and books they offer.

Should I just jump into it and try to invest in my first property with not much experience besides the many investing books I've read?

That's the opportunity.I also recommend engaging an 'investment focused' realtor (not the general residential ones) to guide you through the process and provide you with market intelligence. 

I would suggest starting with reading the IRC book all the way through multiple times.

We don't have any issue getting it booked up for the season.
