Hello, we've purchased a historic building downtown DC that came with no C of O.

Especially w first few deals, the sweat-equity partner may only contribute 30% of value, so 30-70 is the arrangement, especially if it's a short-term JV...I think we hear the 50-50 talk from established investors who have built a long-term relationship w investor-partners.Yes, we could get into the minutiae of tracking the dollar-value the "worker" brings to the table over time, which I guess is the spirit of the "mini-mortgage" approach: Estimate the value of their sourced-deal if wholesaled; set an hourly wage for office-work/time spent renovating; charge a leasing fee for tenant placement and 10% of rent or whatever each month for PM moving forward...
