Your tenant moved out on Jan 5th.Now, they thought they'd want to stay until Jan 12th, but ended up able to move in the 30 days that would have been required.It doesn't really matter if electronic notice is valid or not, the law still requires the tenant to provide a minimum of 30 days advance notice.

We used HelloSign to get the lease signed electronically.  

I went the free and easy way for electronic rent payments.

If they pay you electronically then if they log in at 12:01 am on the 4th to pay it it's late, if they pay it at 11:59 pm on the 3rd it's not.  

is there any electronic platform like pay pal that she can use.

im looking to have my tenant sign her lease electronically, does anyone have any experience completing a eLease.

Like recurring electronic bill pay, but directly to another person, fee-free?

Your tenants can pay the rent electronically (via Zelle, for example).

There was a small disclosure of an issue in the sales contract, but I will admit to glossing over it in signing the electronic papers (the electronic form of signing itself through its extreme convenience can make this easy to do ... so don't!).   

I live in an apartment now with super nice furniture (seriously, my couches are electric and my bed is too), a 50 and 60" tv, electronics, etc.
