Purchase of duplex Help

[Malvin Cuevas]

Hello everyone,

I'm new to the game and will like to purchase my first property in NJ. I found a duplex for $265,000 in good shape and good location. Rent In the area is $1,200 to $1,300 a month for a two bedroom. Taxes are about 5k to 6k . Do you guys think this is a good investment? What is the best way to calculate to see if it makes sense. Please help
