It should be fine to electronically sign it,  but yes you do have to sign it.   

In the future, you could send it electronically using a free service like hellosign.

I have a 4 unit property that I AirBnB the basement out of and already pay for internet at the property. The buzzer system has gone bad and I have been quoted 2.5-3k+ to essentially put in a new, but still same techno...

I ended up having success by getting on the county's distribution for their weekly electronic taxes due file.

These days, if I'm not reading about real estate, I use my free time to pick up new hobbies (SCUBA, woodworking, hobby electronics, HAM radio), tinker in the garage, work out, and of course play with my son. 

@Jason RyersonThe Self-Directed IRA and Solo 401k Differences CONTINUEDThe solo 401k business owner can serve as trustee of the solo 401k;The self-directed IRA participant/owner may not serve as trustee or custodian of her IRA; instead, a trust company or bank institution is required;When distributions commence from the solo 401k a mandatory 20% of federal taxes must be withheld from each distribution and submitted electronically to the IRS by the 15th of the month following the date of each distribution;Rollovers and/or transfers from IRAs or qualified plans (e.g., former employer 401k) to a solo 401k are not reported on Form 5498, but rather on Form 5500-EZ, but only if the air market value of the solo 401k exceeds $250K as of the end of the plan year (generally 12/31);When funds are rolled over or transferred from an IRA or 401k to a self-directed IRA, the amount deposited into the self-directed IRA is reported on Form 5498 by the receiving self-directed IRA custodian by May of the year following the rollover/transfer.Rollovers (provided the 60 day rollover window is satisfied) from an IRA to a Solo 401k or self-directed IRA are reported on lines 15a and 15b of Form 1040;Pre-tax IRA contributions on reported on line 32 of Form 1040;Pre-tax solo 401k contributions are reported on line 28 of Form 1040;Roth solo 401k funds are subject to RMDs;A Roth 401k may be transferred to a Roth IRA (Note that from a planning perspective, it may be advantageous to transfer Roth Solo 401k funds to a Roth IRA before turning age 70 ½ in order to escape the Roth RMD requirement applicable to Roth 401k contributions including Roth Solo 401k contributions and earnings.)

They can swing by the branch, mail it, electronic transfer. 

I would like to do it electronically.  

The lease was electronically signed on April 1st, however the tenants wanted an amendment to the lease.

But I wonder if the electrical sytem could really handle base boards in every room plus any electronics the tenants would plug in.This is the wording from the email from ConEd.
