Sell or hold rental duplex

[Justin Sidwell]

Considering selling my duplex with high prices vs hold. Owner for 3 years, bought for 140k. House hacked and renovated units. All in for 165k. Could sell for 300k ish, mortgage is 830/month at 2.8%. Added detail, I’ve lived there 3 years so I can cash out without paying capital gains. I already bought another house. Rental income is 1800/month. Don’t mind either option, just what is best? I feel like it’s over valued market at this time, my area is growing though and the rental market is good in foreseeable future. What do you guys think?! Hold or cash out. Thanks for input!
