loan amount pay per share

How do I caculate individual partnership share to pay on a real estate
transaction, where each is paying diffrent amount to meet the downpayment,
and then pay the appropriate amount on the loan every month.

Why would it not be proportional to each contribution? For example,assume a purchase of $100,000 is planned with a 25% downpayment and four investors (partners) are planning the following contributions to the $25,000 deposit:
Investor A $4,000; Investor B $5,000; Investor C $6,000 and Investor D $10,000 resulting in the following share proportions of all financial obligations and benefits: Investor A = ($4,000/$25,000) = 16%: Investor B = ($5,000/$25,000) = 20%; Investor C = ($6,000/$25,000) = 24% and Investor D = ($10,000/$25,000) = 40%.
As previously stated, the Investors, adding up to 100%, share each individual proportion of costs that are incurred throughout the holding of the asset as well as benefitting in the same proportionss resulting from the eventual sale of the asset.
I hope I've covered everything. GeorgeF
