Okay to use e-mailed PDF of signed lease or is wet ink required?

[Jason Krawitz]

I'm meeting one of my two new tenants at the property on Saturday to sign the lease and collect the deposit and 1st month's rent. His wife still lives in Florida and is the co-applicant. Is it okay for me to accept an e-mailed copy of her signature on the lease or should I ask that she overnight mail a copy with wet ink on it? Does it matter?

Thanks!
