Analyzing my first rental buy - Duplex and house

[Chase Griffin]

First of all, thank you to those who read this post and offer advice! I am looking to make a move and buy my first rental, an exciting and nervous time for sure! I have found a house that comes with a duplex in my local market that is listed for 400K. I am not sure if this is a good deal or how to go about calculating expenses like taxes, and how to calculate how much I could rent it out for. Any advice on how to analyze this deal and any first time buyer advice would be really appreciated, thank you!
