Best Electronic Signature Software??

[Brian Green]

Hi Bigger Pockets,

My wife and I manage some university apartments and a triplex. We just took over the management for these family-owned properties and in the past, all of the lease agreements were physically signed. We would like to digitize this process and I was wondering if anyone has any recommendations for software? Obviously, there is Docusign but I'm guessing it's expensive for small business?

What do you use? 

Thanks!!
