E-signature software for leases in PDF format?

[Benjamin Lenz]

Hey everyone! 

I'm wondering what programs people are using for tenants who don't live in the area yet and need to sign the lease remotely via e-signature. I currently use LawDepot to download my state specific California residential and then save it in PDF format, but then want to e-sign it myself. I'm not as concerned with how the future tenant will e-sign it as they can always print it out on their end and sign it, scan it, and send it back to me, but with that said I'm not even sure if that's legally binding? Any suggestions would be helpful. Thanks!
