Hi welcome I am a user, not a pro, I can agree with Doug.
The 100mm is a well regarded portrait lens, not often seen S/H it tends to be a keeper, but if you are not shooting portraits/weddings it is less good for Macro,Landscapes. The Zoom is BIG and HEAVY whilst being versatile and has a reputation of equalling the prime equivalents, if you are walking around shooting it is a lot to carry for leisure. The H4D40 is a crop sensor, most are, but that is quite a crop, the series was greatly reduced at the end of line in pricing.
As Doug says you may have done your research and this deal is a fit component wise and we are just looking at cost but I remain to be convinced. What are you shooting, what now in gear, what are you looking for in MFD, does this fit those requirements? It reads like a wedding kit to me, but you need a backup for that, is that budgeted for?
I know you came for a quick answer on cost but like you say you need to see it, so would we to judge condition, is the software up to date, has someone cared for the kit or hammered it?
We want a positive outcome for you, it sounds a bit like a friend of a friend deal, that gives you zero return or warranty rights.
On price look at Hasselblad "approved" / used, I am UK but there is a USA site, then look at e-bay completed, draw up a table with the differences, more research, but you may have the cart in front of the horse, a deal is not a deal worth having if that zoom sits unused and you end up selling on with more hassle. Finally don't dismiss a Phase One back on a H body many find that the best of both worlds and other threads here attest to the deals to be had on their older backs.
Final tip: take that gear list and ring a dealer, say you are selling what's the offer? Remember there is a floor on the price as Hasselblad have a trade in price against new gear for the body.
