Should I reject these applicants and keep looking?

[Jack B.]

I tried ABNB out with one of my rentals last year and am converting it back into a long term rental and also trying mid term rentals until I find a long term tenant. 

Applicant A: Mid term. Travel nurse and her husband plus dog (I don't like dogs and usually don't accept them). They would rent for 3-5 months at 2K a month. It left a bad taste in my mouth that they tried to negotiate the rate down so they could pocket more of the 4K a month the employer is paying for their lodging....plus he's an insurance adjuster so I worry about him trying to pull some kind of "injury" scam while he is here.

Applicant B: Long term. Entitled grown man. Asked if I'd be willing to buy a carport for his parking spot at my expense. I'm like, ugh, no.

Or....option C is I keep it as a short term for now and give ABNB another try this summer. It was booked solid last summer. I'm getting inquiries from insurance companies for my place too, 7K for a 50 day stay...but no deal yet.

So would you rent to Applicant A? Or?
