Feel free to pm me if you want to be in touch with me and a couple of other ladies who are trying to be moms, investors, breadwinners and maintain our sanity!

So I have the opportunity to rent a 20x100 cement pad at a friends well maintained RV park for only $200 a month.

That is what you need to concentrate on. 

Then you'll have to sign up with a NJ brokerage to maintain your license, for which you'll pay a minimum of $200/year in errors and omissions insurance.

After the great recession, FNMA and FMCC were about 100%... they maintained liquidity virtually single handedly after Lehman Brothers and other investment banks (major firms securitizing home loans) collapsed.

During the course of the 7 years, a caretaker will live in the basement and will maintain the property and perform other duties in exchange for a reduced monthly charge.  

—In all criminal cases, contempt cases, and other cases filed pursuant to this chapter, if a party has sold, leased, or let real estate, the title to which was not in the party when it was offered for sale, lease, or letting, or such party has maintained an office bearing signs that real estate is for sale, lease, or rental thereat, or has advertised real estate for sale, lease, or rental, generally, or describing property, the title to which was not in such party at the time, it shall be a presumption that such party was acting or attempting to act as a real estate broker, and the burden of proof shall be upon him or her to show that he or she was not acting or attempting to act as a broker or sales associate.

I'm actually an advocate for raising dues a little every year as it allows the HOA to maintain the property in an attractive manner to bring in excellent tenants.  

concentration, mental awareness and a survival instinct are very much in order.
