It is about a woman whose husband leaves her with no money. She doesn't have a job. She rents rooms in her house to survive. All of the renters become a family and help each other.

Could this be a British movie called "Saving Grace?" Here's a brief plot summary:

A widow (Brenda Blethyn) discovers after her husband's suicide that he has mortgaged everything they own and the banks are ready to foreclose. Faced with impending doom and little working knowledge except her ability to grow plants, she struggles to save her home. Enter her gardener (Craig Ferguson), who is struggling to make a few marijuana plants grow in a hidden location and suggests that she use her green house to help grow the plants and sell them to make the money both need. He is wanting to get married, but needs capital. What he doesn't know is that his girl friend (Valerie Edmond) is pregnant and thus fears that they will be busted for growing marijuana. While supposedly working, the whole village including the local constable is well aware of the endeavor and is hoping for their success. When the plants come in, Grace takes the crop to London and tries to sell it to a ruthless, but charming drug dealer (Thcheky Karyo). Everything busts loose from there.

Even if this isn't the one, it's worth seeing. It was hilarious!
