How would you split the ownership on this joint venture

[Daniel H.]

There are two business partners (John and Sean) who jointly purchase a rental property.

Sean found the rental property and identified it as a good investment.

John invests 100k to purchase the property completely (no mortgage).

Sean invests 20k to rehab the property and handles all the hands on work of managing contractors, and renting out the property.

How would you split the net rental income and ownership of the property?

Thanks.
