Selling duplex to capitalize on equity?

[Thomas Santos]

So a little bit of a rundown, I purchased a duplex in early 2017 for for 299k i used a fha loan. I currently owe 285k on the property and similar homes are selling in The 450-460k range is this to much to pass up on? I don’t need to sell the property it currently produces a 12% cap rate (if i move out) my plan is to buy another investment property which i almost have enough for a down payment. so i guess it’s really a matter of will the profit help me purchase more investment properties a bit quicker however ill be losing a great investment property in the mean time. It’s a very tempting paycheck just want some feed back, Thanks.
