Is it time to sell my 1st Rental Property in NJ?

[Armando Paz]

Hi all! 1st time poster here, but lurked for quite a while.

I currently have my first rental property (3 family in Paterson, NJ) that is fully rented and going strong so far. With the market being in favor of sellers here, is it time for me to let it go? I've had the property for about 4.5 years and maintained it myself. If I did decide to sell it'd be with the intention to reinvest in another area when property prices go back down and houses appreciate more. I'm not planning on retiring soon (29 Y/O). Any advice is greatly appreciated. 

Some details:

3 fam, mortgage of $2100 (taxes are about $8,600 and climbing), Monthly gross income of $3,100, balance of $160k and estimated market value from what I've seen is $340-350k. If it sells for $345k I'll be netting about $120k give or take after taxes and fees.
