Private Equity Books

[Brandon Roberts]

Hey guys! Just recently purchased my first two properties with conventional 15-yr mortgages. This of course maxed out my debt to income ratio, making it very hard for me to get another conventional loan this year. My goal is to buy three more properties by the end of 2018 by using my parents as private equity lenders since they have a decent amount of cash saved up (over 100k) and are willing to lend me some of the money. Do you have any advice on different strategies about putting a deal like this together or could you recommend any good books/articles to read before I jump into this adventure? 

Thanks in advance for your help!
