Any advice for my first eviction in MN?

[Jennifer Rysdam]

I have a drunk, disruptive, rude, pot smoking, 65 year old tenant on a month-to-month that I gave 30 days notice to last month. He decided not to pay the rent, so I gave him the $25 late fee and then a 14 day notice to pay or quit. He's still there. He's been saying he was moving out on the 30th but might need more time because he had to wait for someone else to move. Now he says he bought a house and is closing the end of the week. All lies. I'm charging him double rent since the 20th, per the lease agreement, and now I need to file the eviction. Any advice?? I'm hiring an attorney. He says it could cost up to $1500 but that it will be cut and dry since it's a month-to-month lease and I gave him the proper notice.
