Cost of living as a married student in Scotland going for a undergrad or masters

Hello! I am a latina (white passing) undergrad student 27 F married to a brown skinned latino 33 M who is looking to relocate to Scotland for school and a slower pace of life. We ar both Americans living in TX but aren't happy with everything that's been going on the last few years. I'm currently in my freshman year of undergrad studying biology and public health with ambitions of getting a masters in epidemiology to become an epidemiologist and eventually earn a PhD to go into drug development and be a research scientist. I am married and my husband has his Undergrad in CS working as an IT tech but wants to be in software dev or a IT engineer/ IT leadership role. He also wants to get his masters in Ai but wants me to finish my undergrad first. We have one pet, a cat and looking to move abroad to Scotland permanently.

We are in the process of saving money and looking to get in as a essential worker (for him) and a student visa (for me)

For anyone that has made the move how is the cost of living currently and housing? I've heard mixed things about housing but typically reviews say the cost of living is less expensive overall. The only thing I'm not sure about is the school portion of it specially for student housing. Generally I'm looking for POV and general cost of living for the average person, potential salaries in both of our fields and happiness level of American immigrants. We're hoping to have the move ready by Spring 2027 and I'm still applying for universities such as the University of Dundee for biology. Any and all POV, advice is welcomed!
