How would you organize this real estate partnership?

[Nick Burns]

I'm not sure how to design this business partnership. 

Scenario: 2 deeded properties that abut one another that share a driveway with a 14 car parking lot (the parking lot is split in the middle, but the driveway is now considered a right of way.)  8 - units, can rent seasonally as it's located in a tourist town for beach rentals. 

Ideally my brother and I would buy the property together and form an LLC and run as a business.

However, my wife doesn't want to enter a "business" relationship with my brother, but instead suggests that we purchase the properties individually (since they are both on seperate deeds).

One property has a commerical space in the front that historically has been used as a take-out food stand, which could be profitable.  This same building has an ocean view and is listed $25,000 more than the other builiding which is priced at $425,000. This building clearly is the better of the two because of the ocean view and commerical unit. 

Therefore, a partnership makes sense so that the entire 8-units and commercial space is run by one entity which splits the income and expenses appropriately.

Since my wife doesn't want to engage in a direct business relationship with my brother, she would prefer for us to purchase the properties seperately; how would you suggest to organize this purchase so that both parties are satisfied?

We could share expenses such as cleaning company, property management, supplies, etc. 

The tricky part is the commercial space which could be very profitable since there is a lot of tourists and foot traffic in the area.  

How would you suggest organizing this purchase so it makes sense for both parties?

Any suggestions would be greatly appreciated.
