If this is what concerns you hire a buyer's agent because you are focused on the wrong things altogether.

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.

The next level up is hiring a revenue management company or VA to do this for you.

Or hire a professional who specializes in selling this type of asset.

Be professional, kind and firm. 

Horrible tenants increase cautiousness and interaction with insurance Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

When it comes to being a real estate professional, it actually doesn’t have anything to do with your job title or profession.

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?

Do you have the professionals you need to start an LLC, do the proper real estate/tax accounting, solid contractors to rehab or prepare the property, and a property manager to handle the day-to-day operations? 

Maybe they are bad communicators.Assuming you still want the place, I would do anything you want to reach out via the renal address or professional websites, but home addresses and personal social media is going too far.
