Contracts for purchase besides AOS

[Dan Deckelbaum]

Hi, for my more experienced purchasers out there. I’m a Realtor and starting to build a portfolio in Philly. Doorknockers going out next week. Private funds lined up! Do you use a contract besides the state agreement of sale to purchase?  Does anyone have an example, or one they use in PA? Dandeckelbaumgmailcom if you have one to send. 

Im also looking for software for project management and property management if anyone has products they love. 

Thanks in advance!
