You could hire property management and probably still do well although I am not sure of the options in that city.- If I use a 1031 Exchange, does the next property also have to be a duplex?

If you don't have experience, hire a public adjuster.

I just recently got hired for DSNY (New York city department of sanitation) my base pay is 43,000 with alot of overtime opportunities so I do not see myself making any less than 60,000 for my first year.

I hire a contractor to jet the line. 

You probably do not qualify for REPS, but it has nothing to do with 1099s.

How do I navigate this situation and any recommendations for hiring professional for furnishing and for taking photos. 

You hired a management company?

Here is a guide for our water company that walks you through it:  https://www.portland.gov/water/water-efficiency-programs/fin...I'm guessing it would be pretty similar for you, and if you determine that there is a leak by looking at the meter, then you may want to hire the leak detection company.As someone else pointed out, maybe just ask your tenants as well if any toilets are running or "ghost flushing" or if they have noticed any drips.Good luck!

Quote from @Jeff Brogan: I would hire a trusted expert to get you real numbers, someone that does it in that area all the time (rents out properties/property management).
