newbie and need help!

[Oscka Flocka]

I've been saving my money up for a bit now and have been studying/looking into investing in real estate for a while now also. I want my first investment to be a good investment. so there's currently a 2br/2ba duplex for sale with tenants in place for $95,000 (so zillow says, heard zillow was inaccurate) but anyways, was wondering if that would be a good start off investment for me. zillow also says the the estimate mortgage is $500 and estimate rent per month is $785. was wondering if there is a way I can get that confirmed somehow. would love input and feedback from yall! thanks!
