I can't work with them at all because they refuse to provide the original purchase and sale agreement.

Michelle,In the NYC market, i think our best search resource is Streeteasy, it's the most up to date and provides the most accurate historical sales data. 

I can't quite figure out where the pinch points are happening. 

Once that happens, you figure out that cash flow can't touch appreciation.

You guys should also be aware that this can happen when you list a house for sale as well.We listed my grandmother's house for sale last year after she passed away, and within just a couple days, our listing agent was getting calls about "the house for rent."

The idea that you can build wealth without putting any money into it is a recipe for disaster and the sales pitch of gurus trying to steal your money.

Is there opportunity to put some money into your current home to increase the equity and sell (you would need to get more than $1 back in the sale for every $1 put into it)?

@Dominick Tonnarini, The only issue with your plan is that you will have to pay a sizable tax on the sale of that property when you do sell. 

Reverse engineer that and you can figure out how many properties you will need to reach that goal.Best of luck
