Beautiful property.
Long term stays are not can you tempt but is that a market interest in your area. People looking foe a 3 bedroom house even for 28 days aren't usually a family but a group of employees either trying to save lodging or transportation costs or both. I have had no issues with mine but my setup though I like attractive durability and functionality are also priorities.
I have never tried this but a possible thought is marketing your listing to realtors that might have family clients waiting to close. The realtors could advise you what market price to charge maybe for a minimum 28 day rental.
