If you're interested in real estate investment and willing to do trivial math, I'd recommend Frank Gallinelli's book ( http://www.amazon.com/Every-Estate-Investor-Financial-Measur... ) for the basics.

He comes across as a great guy (heard him interviewed on a podcast before I bought the book), has a really readable style (seriously, it makes real estate financials "light reading"), and generally seems focused on helping people (he was apparently teaching when a publisher approached him to write a book - he told them he wouldn't write the book they wanted because he thought it would be useless, but he would write them a book on what he thought would be most useful).

And absolutely: if you're from a comp-sci background, the real estate math is all trivial plug and chug. But it is worth learning the accepted ways of doing things so you can properly compare and model your properties.
