Your residency in Maine ended on February 2. None of the other dates matter.
It doesn't matter where your bank is. Pension payments or IRA distributions that you received on or before Feb. 2 are Maine income, and any payments or distributions you received after Feb. 2 are not Maine income.
The sale of the house in Maine is Maine income, and you have to report it on your Maine tax return. Any profit on the sale is subject to Maine income tax, in addition to the pension payments and IRA distributions that you received on or before Feb. 2. I don't know if Maine follows the federal rules for excluding gain on the sale of your home. You might not actually have to pay any tax on it. The TurboTax interview for Maine should lead you through figuring it out.
