You have to have comnparables and Montana is a big place with numbers all over the Board. Again the best advice is to get a good Realtor. We keep saying it but that is because you need that. I am from Oregon and I bought Property is Montana and I have been going there my whole life. I found out by asking around who was the top agent in the valley.
I called that agent and a couple of others and than I made my move. I looked at comps and it was not easy but it worked out ok. The Realtor helped me a lot in that Scenario. Hopefully this will help! Montana is a great State! Man I loved it up there.
