Based on the fact he is asking for a discount, I would decline the offer to host him!
Like you I would not hold the 'newbie' tag against him. Some of my nicest guests have been 'cleanskins' but when you accept a reservation you need something more than an email address and the name 'Tuna' to go by!
He seems to strike out on all three major hosting guidelines.
A/. No proper verification!
B/. No past reviews!
C/. He wants a discount!
You guys have been around the Airbnb traps for long enough now to have developed a feel for who is worth hosting and who is not...and from the way I read it, your question answered your question!
You have made your decision already....and I think it is the right one.
All the best to you both.
Cheers.....Rob
