For books The Tribe of Mentors and 4 hour work week by Tim Ferris are amazing.

Most of the court cases I have tried recently are requiring additional time for giving notice, and are Not counting Saturday and Sunday as Work Week business days.I know this method maybe a little dated but it is what the courts accept readily and if the Landlord does Not sign for the certified letter then you just send them a follow up email and use the Certified Mail receipt to indicate attempts were made to notify Landlord prior to 30 days of termination of lease.

Refer to the book, Four Hour Work Week by Tim Ferris for info on this topic (I'm not sure if that's the exact title or author name but a Google search will make the book obvious).

Books I would recommend however are Rich Dad Poor Dad, Four Hour Work Week, and Millionaire Real Estate Investor. 

There are also several blog articles on tenant screening, which is hugely important, and Brandon Turner's Ultimate Guide to Tenant Screening is chock-full of great advice.http://www.biggerpockets.com/renewsblog/2013/01/27...As you'll see, the theme of automation (a la E-myth and 4Hour Work Week philosophies) plays a large role in this site. 

@Dean Letfus   I feel that with what we have accomplished while working around a full time job that consist of 40+ hour work weeks, we should be able to fast forward the growth if we dedicated all our time to real estate investing. 

I got the points idea from the book Four Hour Work Week by Tim Ferris back in 2007.

The change in real average hourly earnings combined with a decrease of 0.6 percent in the average workweek resulted in a 3.4-percent decrease in real average weekly earnings over this period.""

Read the 4-Hour Workweek or 80/20 by Richard Koch.

I've spaced my work week out to have quality time to spend on learning this business and I am now looking for the best way to spend that time.
