They may also be able to get together and file a lawsuit blocking the action.

Your phone number gets blocked as "SPAM" nowadays.

@Marc Jackson what would you call the average performance (gross income and net income) from a PCB Townhome within say 5 blocks of the water?

They are building a new town center at the corner of my block (literally) with over 1300 new apartment units, 250k sq ft of office, and retail space.

We are currently working on another house a block away that will be a 4bed/3bath w/ 1800 sq/ft and in the last year, 3 full gut Renovations on the same block have sold for 475k, 465k, and 450k.

Six lots up from me on the corner a Broker sold a 3/2 block home, without a garage or fence for $383,000 six months ago in one week.

Appfolio or Buildium will be a good building block for your growth.

From there you can dive into more advanced books, but if you don't have the building blocks, those may be overkill.Also consider buying Michael Blank's analyzer tool, comes with video training.Also consider buying David Toupin's analyzer tool, then find his walk-throughs on his youtube channel of how to use it.

I thought about just blocking the vents on the second floor, but it can mess up the air handler if I reduce the CFM its meant for? 

If you "live in a good-ole-boy town where we were given this opportunity because we knew some people and I don't think they would sell it to our friends", that means they will figure out what you are trying to do and block it.
