However one thing I didn't anticipate was, while the aged sewer line could easily hand two people living in the property, when my tenants moved in and when the load on the sewer system went to five people, it couldn't keep up.Turns out the line had been damaged over time (orangeburg pipe) and was too narrow, so I had to pay to get it replaced. 

i'd keep saving and keep learning.

The key, imo, will be to keep an eye on NYC residents entering the NJ home buying market.

But as my track record of success grew I was able to keep more for myself.

But I am quite a bit younger than you and tend to keep my properties leveraged.

Alongside Seller negotiation I think you have to keep in mind the financing for the deal and it's requirements as well as the interest rate.

:1) First, buy the land and a mobile home within 60 days of each other and have the mobile home moved there, keeping the hitch and axle and wheels in place 2) Second, get a perimeter wall or concrete pillar every 8 feet built under the  frame of the mobile home.

But fear not, my fellow investors, because these issues are slowly but surely getting better, and with the simple diligence of keeping an eye on those sneaky property taxes, along with the ever-increasing insurance costs, you will do great.Speaking of golden opportunities, the MHC market has become more institutional, meaning more opportunities for those of us with a keen eye for quality investments.

I am wondering if I should keep the water meters in my name and get rid of one water meter and let each meter service 2 apartments?

Thanks for the input @Russell Brazil, I'll definitely keep that in mind, as I would really like my place to appreciate over time, even if it's a little bit.
