I've connected with wholesalers and turn-key companies to find deals, but now I'm not sure how to move forward with verifying everything that is presented electronically. 

 I have them electronically pay rent  via ACH transfer, have them set it up at their bank.   

Our local recorders and treasurers websites are all electronic here so you can do a lot of your own research to make sure the lien is in first position and see if there are any special assessments or anything.

The investor is looking at a prospectus, the trust is just receiving the electronic chattel paper, and the issuer is not going to be reviewing chain of title as they create pools.

A lessor of residential real property, containing 5 or more units, who has received a security deposit from a lessee to secure the payment of rent or to compensate for damage to the leased property may not withhold any part of that deposit as compensation for property damage unless he has, within 30 days of the date that the lessee vacated the premises, furnished to the lessee, delivered in person, by mail directed to his last known address, or by electronic mail to a verified electronic mail address provided by the lessee, an itemized statement of the damage allegedly caused to the premises and the estimated or actual cost for repairing or replacing each item on that statement, attaching the paid receipts, or copies thereof, for the repair or replacement.

@Anil Samuel If it is a lease renewal and you are just working on the mechanics of signing the lease, you might consider using an electronic signature service like  Adobe EchoSign.  

It is still recommended, even though in some cases it is not required.And an important exception: no need for 1099s if you paid your contractors via electronic means like credit cards or PayPal.There're more rules related to 1099s, which is why it's best to ask your own CPA about your own situation.  

I am reluctant to go electronic with rent collections because......If I am evicting somebody - serve them the three-day, file an eviction, and then they pay me ten bucks through the service and spoil the eviction....?  

All electronic key-pad locks look like a good option.

Another warning: Zelle payments are not considered electronic payments and they DO require 1099s
