This led me to a town called South Amboy in NJ.

You're not sharing thew whole story, and it only your side of the story, so it's difficult to give advice.Time is money, and no one wants to work for free, so the PMC probably feels that they want something for all their time invested in taking pics, writing an ad, publishing and taking all the phone calls and handling showings. 

Shoot me a DM and we can set up a call. 

The disadvantages would be the high interest rate, the need to refinance, and the lower ROI given the expensive cost of the money, resulting in a lower amount of profit each month.Then, there is your personal line in the sand, where you have to make the judgment call of “is the investment worth it”?  

(Cold call, mail etc)

If he goes (or I go) and we determine the job is to big for him (or I) to handle, then we call out a service guy and materials and labor is charged.

most of the calls coming are having only child support  or $1000 to $1700  income per month . 

Open houses, Door Knocking, cold calling, etc.

Have a phone call with the Net Lease Group at Cushman Wakefield.

I have one client who buys new and gets the 5 year warranty on all appliances and tapes it on there so if there is ever a problem the tenant calls the warranty company.
