We are putting in tons of extra hours contacting tenants via phone, text and email. 

 I would like to know, is there a phone script either through/on bigger pockets, online, or somewhere you can suggest, that I can use to negotiate a deal with a motivated seller to be able to get a contract if so I'd appreciate it thanks?

I got him on the phone, we met up and got to know each other.

Would the contractor need to visit the house or do contractors give general estimates over the phone?

I would say they should limit accounts to 1 per phone number or ip address but I suppose professional trolls would get past that. 

You can also do much of the business through phone calls and email. 

Get a phone number for company and ask if you can contact the property owner for a reference.

You'll have much more success in your search if you tell us in what city and state you operate.Also, specifics help: You might consider listing some of the admin tasks you have performed or can perform.Good luck!

I am willing to help you out with some advice or even chat on the phone if you wish.

One can learn a lot by phone.
