Hi Carla,
If it were me, I'd sit down with the potential partner (over a business meal to make it a little more relaxed) and discuss upfront the things that the two of you think might cause the partnership to go wrong. Get those questions out in the open and try to solve them ahead of time.
You can discuss:
- Profit splits.
- Depreciation splits.
- Who is going to pay for what percent of the startup costs.
- Who is going to do what.
- What happens if someone cannot do their part.
- What happens if someone does not do their part.
- Who will cover any losses.
- What if one person cannot cover a loss.
- How will you handle any added money that is needed in the future.
- etc...
Then when you have some of that hashed out, both sit down with an Real Estate Attorney who form LLC's and talk to him about it.
Good partnerships are about good communication.
As far as splits, rather than think what is good for you, maybe think what is (fair) for her, and go from there. That might give you some additional thoughts in this very important subject.
I like Olive Garden after the lunch rush.
Good Luck!
