@Jughead, you sound frustrated, so I hope that your choice of words and the points you’ve made are only indicative of an incident and not something that is festering.
I see this as 2 separate issues:
- a business relationship with another person (business - keep it business, at least until you’re married)
- her living with you - should she pay you to live there? (personal)
What you decide on point #2 is up to you. I see this forum as trying to help with #1, although I’m sure there are a lot of armchair psychologists that would love to help with that, too.
I have 2 suggestions:
a. figure out how much you want to make on the lake house as a long-term rental. Make it fair to yourself - don’t end up feeling like you haven’t charged enough or you’ll get resentful. Then rent it to your girlfriend for that amount as a monthly rental. If it’s worth more in the summer and less in the winter than charge her accordingly.
Then, let her do what she wants with it. She can put her furniture in, she can charge what she wants, do the cleaning, run her business. You still get your monthly rental no matter what she does. It separates the two businesses - yours as a property owner renting long term, and hers as a short-term rental manager.
b. If you still want to go with a percentage, I would do a 70 (owner) / 30 (manager) split plus she gets paid by the hour for whatever cleaning she does - a fair amount. Believe me it adds up!
My armchair psychologist side is concerned with this statement if you’re working together for the benefit of each other, as a loving couple should. I’m not taking sides, it’s obvious that this is a bone of contention between you. But whatever you furnish it with will definitely get some wear n’ tear on it and will need to be replaced at some point.
In this scenario I think that, as the owner, you should provide the furniture - so purchase the furniture from her (if it is suitable for the house). It then becomes yours, should you end up going your separate ways. In case you do, what you pay and the amount she saves from not having to store it will help to pay for new furniture when she moves out.
