I’ve found a four plex that i think 2 units would pay the mortgage with the other 2 as monthly income. I watched a lot of videos lately on real estate but would like to get other sources on whether it would be worth my time.

First of all you need to talk to the mortgage lender validating your conclusion with all documentations. 

@Darrell Brock it is worth your time. The worst case scenario is you own a property and you have to rehab a bit to turn it into a flip as opposed to doing it as a rental property. Im not saying buy a bad deal but use the BP calculators to run the numbers on the property to see if its worth the money and as @Sam Shueh said talk to your lender first to see if you qualify for that deal.

@Darrell Brock I agree with @Anthony W.  Use the calculators and ensure your numbers works. In the if the deal works then try it. I also agree with @Sam Shueh to get your financing lined up if you haven't. As an investor I always make sure I have multiple funding options available for multiple situations. When you see a deal you want to spend the time analyzing the deal not financing it.
