Read the classic- rich dad poor day by Robert Kiyosaki.

Classic example of a prohibited transaction.

Two titles I like on practical advice are: (1) Leigh Robinson's Landlording, it has an iconic yellow cover and is a classic (about any recent edition works)2)  And for more on acquisition and adding value to rentals of the type you mention (even creative strategies) I also recommend Jay P.

The color is classic.

Now I'm looking to find a 100 plus doors to take to the studs, and breath some new life into yet another classic property!!!

"Correlation is not necessarily causation," classic from econometrics.

It is time to do some upgrades (carpeting getting worn, etc.) and I am contemplating repurposing the property as a "Vacation rental home" to make available to people who spend the weekend for games, parent weekends, etc.  

Sounds like you're doing all the right things - so don't do the classic newbie/neverbe thing and be afraid to act.

A classic book for this is Dale Carnegie's 'How to Win Friends and Influence People'.

As a Real estate agent, I do a lot of cold calls and i'm familiar with expired listing, fsbo,and just classic cold calls..so I started to create a buyer database that might be my potentials buyers in the future.
