What do you know about duplexes?

[Aaron St. Clair]

I am interested in learning the market around the Lubbock area.  My wife and I are living in a single family home that we moved in to back in nov 2019.  I have aquired equity in the home and the thought of using said equity to start investing in real estate has crossed my mind.  I am not sold on it but while reading Brandon Turner's books he is constantly using the phrase "think 'how can I do this,' not 'I can't do this.'"  So in the spirit of embracing this new mindset I am think "How can i use the equity we have acquired to invest in real estate and grow our money?"  One thought is to sell our home and move into a duplex, triplex, or even quadruplex.  I am just using the thought process if a duplex for now to avoid paralysis of analysis.  All this being said, what are some advantages, disadvantages, and insights you have with duplexes?  Any and all responses are welcome however I am particularly interested in learning from people with knowledge about duplexes in my area.
