Shelly,
Is your financial partner willing to pay for the acquisition and the rehab costs? I would not agree as the financial partner to pay a "salary" for the work that needs to be done. I would be more comfortable paying for certain things getting done. You and your money partner could agree in advance how much your husband will get paid for what particular work he completes.
Having said that, what are you and your husband bringing to the table for this deal? If you are going to get half the profit at the end of the deal what are you doing for your half? If your husband is getting paid for the work he is doing on the property he is getting compensated for his time. So is your half of the profit based on you finding the deals, and negotiating the deals? I bring up those questions to highlight that I would look at it from your money investors view point to make sure you keep him or her happy. Would he or she be better off to hire their own contractor and pay them to do properties and not have to split the profit with you or anyone else?
I have done a lot of deals where I had a money partner, but I have never taken any pay for work I did on the property. I find the deals, negotiate the deals, plan and oversee the rehab, get supplies, coordinate for utilities, and have did a lot of rehab work on the properties over the years. From my perspective I earn my cut whether that is 50% or whatever is decided by doing those things. I don't take a salary or pay for my labor and half of the profit. Which means I have to have money to live on or other sources of income to keep me going during a project. I should only make my money (profit) when the deal is successful and my money partner gets their cut.
Having said all of that, as long as both parties agree to the terms then there should be no hurt feelings.
