Please feel free to reach out to me and my team if you would like to come up with a game plan and build your buy box. 

My goal is to rent it out to start generating some cash flow.I’m planning to remodel the kitchen soon, and once that’s done, I’d like to move out to make the apartment available for renters.

Now I am brand new to real estate so this could be dumb but I'm reading Brandon Turners "Rental Property Investing" book and I was intrigued by chapter 3 where he list out 4 plans to start with when getting into real estate.

Generally there are multiple units for each "zone" if you will when I've seen them installed.Regarding your problem at hand, I personally would simply adjust your plan to move and make your initial plan to get the current issues resolved, while costly now, in the long run holding onto the unit will likely pay off. 

I currently have my investment portfolio all in North Jersey and planning on purchasing a number of units in Syracuse.

I use this for tax and insurance which all properties have)Expenses (general business like admin/legal and by unit for repairs, trash, utilities...)EBITDA (earnings before interest/taxes/depreciation/amortization.

Let me know if you plan to make it so I can let the owner know and he can make sure they are properly prepared.
