21 year old looking to my first property (Duplex)

[Avery Evans]

Hello! Discovered bigger pockets a few months ago and I'm learning a ton. This is my first post on the forum, and hopefully some of you with more experience could take a look at the numbers of the duplex I'm looking at in Lexington, KY. The duplex is $164,500 and is one-story with 2 identical units. It's in a decent suburban area in Lexington and sits on a street with single-family homes, so the street is well kept. The inside has been updated within the past 5 years. One unit is occupied renting at $750 a month (which I feel like could really be $900) and the other is vacant. My goal for this would be for my wife and I to move into the vacant unit, saving us our current apartment rent of $1,090. This would allow us to get an FHA loan, which is ideal because, at 21, our current ability to pay a down payment is limited to about $15,000. From my calculation, the mortgage would be $700, taxes $115, utilities $100 (for our side) and general expenses $100. This is $1,015 per month minus rent income of $750, so our out-of-pocket would be $250-300 a month, saving us a lot from paying $1,090 and also at the same time gaining small amounts of equity in the property. Is my analysis on this correct? Am I forgetting anything?

Thanks!
