When her 40 year marriage abruptly ends, a professional Nurse impulsively accepts an invitation to caretake a 400 year old cottage on a small Greek Island, to discover that between the eccentric locals and her complicated housemate the journey back to self is far from peaceful. #For Meetup

Pretty good logline, however I don't understand how the "complicated housemate" fits the idea?

I like your story idea, Jax. Some might say that you should be more specific describing how the eccentric locals and the complicated housemate create obstacles that get in the way of her reaching freedom. But I think you've provided enough to pique the curiosity of a reader. But, of course, I could be wrong. I don't claim to be any sort of logline expert. LOL

I've also rewritten your logline. Not necessarily saying it's any better than yours - simply couldn't help myself. LOL again.

After her 40-year marriage disintegrates, a retired nurse embraces her newfound freedom by impulsively accepting a job as caretaker of a quaint estate on a small Greek island ? but between the eccentric locals and her complicated housemate, this late bloomer discovers the road to freedom is far from peaceful.

I've considered that Lee, but thanks to the movies you've mentioned I hope the way has been paved! Much of the comedy would be lost with a younger cast, so it is pivotal.

2nd attempt:
When her 40 year marriage disintegrates a retired Nurse embracing her new freedom impulsively accepts an invitation to caretake an ancient cottage and garden in the Greek Islands - but between the eccentric locals and her complicated housemate this late bloomer discovers the road to freedom is far from peaceful.

As The Best Exotic Marigold Hotel proved, movies with an older cast can do well at the box office - according to IMDB, it cost $10,000,000 and grossed over $46,000,000. But unless your script is good enough to attract the likes of Maggie Smith, Judi Dench and Bill Nighy, make your characters younger if you can. I'm not saying don't do it; I'm saying do it only if your story wouldn't work otherwise.

>>journey back to self

What does that mean? What's the visual of the "self" that will show the audience she's succeeded?

It seems to me that "journey back to self" is akin to logline mistake #6 in the article, "must discover something" and "come to terms with". It's about a subjective need which is internal, out of sight. A logline is about an objective goal, something external, tangible, something that can be visualized.
