When discussing his favorite book, Warren Buffett, who reads approximately five to six hours a day, remarked, ‘‘I can’t remember what I paid for the first copy of 'The Intelligent Investor.' Whatever the cost, it would underscore the truth of Ben [Graham]’s adage: Price is what you pay; value is what you get. Of all the investments I ever made, buying Ben’s book was the best.’’

Investing with No Money Down

"The Book on Investing in Real Estate With No (and Low) Money Down" (2014), by Brandon Turner

Unlike stocks, bonds, and mutual funds, investing in real estate requires a significant amount of money. Even if an investor plans to finance the acquisition or development of a property with debt, he or she will still need to have enough money to make a strong down payment to secure a loan.

Although this might sound like a deal breaker for investors who simply do not have large cash reserves, "The Book on Investing in Real Estate with No (and Low) Money Down" provides practical strategies to overcome such dilemma. These include forming partnerships with individuals who have money to invest and using hard money lenders. The book was written by Brandon Turner, who is the co-founder of BiggerPockets.com, an online social network with more than 400,000 rental property investors.

How to Manage Rentals

"The Book on Managing Rental Properties" (2015), by Brandon and Heather Turner

"The Book on Managing Rental Properties" was also written by Brandon Turner, along with his wife, Heather. It serves as a comprehensive guide for rental property owners after they have closed on their deals. In the book, the Turners provide advice on a wide range of aspects associated with the day-to-day property management. This includes how to actually find and screen tenants, how to properly collect rent owed to you, as well as important clauses to include in your rental lease and bookkeeping tips.

Considering Cash Flow

Protect Yourself

Taxes

"Every Landlord's Tax Deduction Guide" (2015, 12th ed.), by Stephen Fishman J.D.

Every year, many rental property investors overstate their net income. This results in a higher than needed tax bill. Jamaican Billionaire Michael Lee-Chin once remarked that in order to be a successful investor, one needs to "minimize their taxes." "Every Landlord’s Tax Deduction Guide" shares a long list of available deductions that are often forgotten by real estate investors. Knowing this can help reduce an investor’s tax liabilities while staying on the right side of the IRS.

Grow Your Empire

"Multi-Family Millions" (2008), by David Lindahl
