New Investor from Indianapolis, Indiana

My name is Beau Benjamin and I am a brand new real estate investor.  I am getting married in less than a month and then will be moving into a house given to us by my fiance's dad.

I've always wanted to rent properties and I bought the house I am currently living in with that in mind ~5 years ago.  Now when I move into our new house, I will want to start renting mine.  I'm not really sure what all that entails, but I'm here to learn.

My fiance also has a condo that she owns that I want to rent out as well.  

I am really excited to start this stage of our lives and want to try to get all of the advice possible to reduce my mistakes, etc.

Thank you for any tips you might provide in advance.

Beau
