Partners - determining who brings more cash

[Brandon Archambault]

Hello everyone, first time poster here. I have a modest 11 unit portfolio myself and am looking to start investing with my (unmarried) life partner. We thought the best way to do this would be to start and LLC together 50/50. We now need to determine how much each of us will bring to the closing table for our first property.

The situation: I am in part time commission only sales role and am a RE broker. I have time to source deals, walk through the properties, do broker activities (like write many offers), handle the financials, do the admin work, manage the loan process, renovate, and manage the property. My partner has a very demanding job and is a high earner. She's looking to be more hands off, but doesn't mind painting or helping with the reno. 

My questions is how do we decide how much cash each of us brings? I'm sure my time and expertise is worth something, I'm just not sure what. It's also important to me this is mutually beneficial to both parties. I'm open to hearing your thoughts and appreciate any advice you may have.

Thanks in advance!
