Fair share with financing partner

[James R Dean]

I have a couple BRRRR's and am looking to partner with another investor that is not interested in day to day dealings. She has experience but is older and is looking to slow down some. If I find deals and run the property management part, finding tenants, managing property, etc., and she would finance the down payment and the loan is paid by the house, is it normal to assume a 50/50 split of profits or what would be a fair share in this case. I am doing most of the work, and they are providing all of the money. Basically, Investor brings the money and I bring the deals and manage the property with a tenant-in-kind title on property. That way we are not technically partners I believe and don't have to share a tax return I understand. I have better deals than I can afford at this time. Thanks in advance. Other choice is to just borrow from this private lender and not split the profits.
