It's similar to those tenants who pay by mail; they have to factor in delivery days.I would be very careful refunding tenants who paid by PayPal Service. 

Make sure you consider delivery and installation. 

Gas delivery fees alone are about $200/month. 

You want to make sure to give proper notice in terms of time and delivery. 

You can get paid $20-30/hr in most areas for anything from cleaning to tutoring to pet/baby sitting to food delivery.

The notice needs to have the correct language and must be delivered by one of the four allowed methods of delivery for it to be valid in Cook County.

Delivery workers, property workers, landscapers, contractors, your mailman, your garbage man, your meter readers, etc., are great for this because they are driving neighborhoods everyday anyway.

They have a very small footprint but the counterpoint is they bring a strong level of service to their delivery.

Complicate that by the fact that those investors will pay in advance for a promise 3-6 months down the line for delivery and you may not be the turn key guys favorite customer.They want easy sales!!! 

Good news is he didn't say no and I learned that I really need to work on my negotiation and delivery skills.
