Advice on going for a Master's or PhD

I got into the Master's program at my undergrad(A) but was just offered yesterday to be a PhD student at another institution(B).

I should be clear that I didn't apply for the PhD. My would've been advisor at A quit to work at B and wants me to go with him. He's essentially ensured that I'm guaranteed into B and that he'd be my advisor. We've known each other for the past 2 years and have worked professionally for the past year. If I were to accept his offer, I think he'd make a great advisor. I have early June to make my decision.

This is my last year studying biomedical engineering as an undergrad and until yesterday I hadn't seriously thought about getting a PhD. I honestly wasn't planning on worrying about it until after working in industry for a while. I really enjoy the field I'm in and I can't not see myself doing research. This would also be a tremendous opportunity to grow as a student while also living in a new area; A is on the west coast, B is on the east coast of the USA. At the same time I'm unsure by whether I'm ready for this type of commitment and work.

I don't want to regret my decision so I'm making a thorough pros and cons list:

Things I have to consider so far:

• Degree (What do I want out of it)

• Financial Burdens (tuition, cost of living, stipend, health insurance)

• Quality of Education (research focused, institution reputation, access to funds/equipment)

• Time (degree completion)

• Job Market Post degree (industry, professor, more research)

• Location (how far is family, access to the outdoors, how safe the area is)*

Does the gradschool community have any thoughts on this?

What else should I find out before making a decision?

If you've been in a similar position, how did you make your choice?

Any advice would be appreciated! Thank you.
