You need to understand what kind of support you're going to have to help you build a practice from the ground up. If there's another group in town, everyone is already going to be calling them for hospital consults and sending their outpatient referrals to them. You need time and support to build a practice in a situation like this.
If the location is good for you, the pay isn't terrible. I'd ask for a 3 year guarantee on the base. And I wouldn't buy a house there until I had 5 or 6 quarters of solid production above the base.
Your money isn't going to come from hospital coverage, it's going to come from infusion. So what's the current/future infusion situation?
What's the support system like in clinic? MA, RN, Infusion staff, pharmacist, SW? Just because somebody wrote "cancer center" on the door in Sharpie doesn't really make it one. I would want, at a minimum: 2 MAs, 1 onc certified pharmacist available to me...not just in the hospital somewhere, 4 RNs, at least one of which is primarily dedicated to triage and coordination but can also cover infusion when needed (and at least one of the other RNs cross-trained for that job), a SW at least 0.5 FTE to start out with an agreement to move to 1.0 when the clinic gets ramped up. If that kind of staffing is in place, or they're willing to pony up for that, I'd say go for it. If they offer you 1 MA, 1 RN and the pager numbers for pharmacy and the hospital SW, just walk away.
