OP, it sounds like you are a PT or "second position" pastor right now. So, in evaluating this, I would look to see how many staff are employed at the church with the offer.
My church has one FT pastor (making closer to what your DH makes), and 1 part time admin, a contract janitor, and a contract musician. That's it. Everything else is volunteer. Vacation coverage is often lay services.
This means that if there is an evening call for hospital visit, or funeral services, that the Pastor is called out to deal with highly emotional situations at all hours... creating a constant feeling of not being able to detach. In response, we provide extremely flexible hours so that she works only 9-3pm each day, has Friday / Sat off, and only a 1/2 day on Sunday. And she works from home one day a week. (Okay, I am a bit side eye at the minimal hours she puts in for the pay). But still, we know that mentally she is "on call" at all times. For very stressed out people at emotional points in their lives.
The other thing, is that as the only employee, she is also like a VP or COO of a business -- having to propose and implement all the programs, engage people, deal with conflict, tend to spiritual needs, etc... with no one to off load most of the extra work (or work that is not in her preferred skill set) to.
She came from a position as a 2nd pastor and as a single mom, found it very stressful to transition. You have tons of support with a spouse, but it is something to consider. I definitely think it is an ideal role when you have kids, for the flexibility and the generous pension and benefits.
I would 100% take the position for a year, and evaluate it. But go in with eyes wide open.
