Yearly cost of a license?

[Tyco Bronye]

I don't know why I can't find this answer. I would like to rehab houses. I live in Minnesota and I would like to get a license to have MLS access and for selling my own properties that I rehabbed.

I am wondering what the yearly costs of this would be?

I thought I read on J scotts blog that his wife paid 300 per month which seems like a lot. I don't know if that was including broker commissions on the sale of a house.
