I've been flipping houses myself since 2003, and I also learned a lot reading (and rereading it). 

I recently went back and re-read the Millionaire Real Estate Investor by Gary Keller.  

@Elle SwansonI just reread what I said about the rental market in CDA.

please re-read the post, because it specifically suggest a LAP SIDING GUN AND A FINISHING NAILER.

After re-reading your post, I see your question was a little more in depth, specifically, related to saving a lot of money in interest over the long term. 

After carefully rereading our rental agreement section 17 on termination says:The leasing period has not expired.

Hi Maria,I agree with Mike re: reading the Blog/Forum posts.

I just finished reading "the book on rental property investing" by Brandon Turner and he goes quite in-depth with it but going back and rereading a chapter every time I want to analyze a property seems very time-consuming.

I just reread my post. 

I just re-read Tom Wheelwright's 'Tax Free Wealth' which does such a great job of pointing out all of the awesome tax "loop holes" for real estate investing.
