So when rents move up from $500 per apt back in the year 2000 to around $1,900 today for one of my buildings, the value of the building increased from $140k back in 2000 to $1.4 Million today.NYC is a Future Value (FV) play.

@David Cruice Primarily because i like the cash flow on the property where it is so i don't want to increase the monthly payment or see a rate increase. 

You'd be better off partnering with one or two other people in a deal this size to increase returns for everyone.

When the cost of money rise (higher interest rates) cap rates increase. its simple investment fundamentals.  

As for learning how to increase your current cash situation you should listen to the BP Money podcast. 

I have recently requested to have my PMI dropped on my primary residence because I believe the value of the property has increased enough to merit the PMI cancellation.

I have rent increases annually at 7% a year to get to market rate by year 4.

Can you imagine, an 8+% rent increase for sales tax? 

The first in Santa Rosa have created an increasingly large housing shortage, providing opportunity to developers. 

I have a great tenant in there (going on 3 years with slight rental increases every year).
