House hack with 3 brothers - How to structure equity %

[Aidan Jones]

We are 3 brothers that are looking at getting into real estate investing together. We would like to get community input on how to structure this investment. We are at different levels with regards to cash on hand and have varying needs with regards to living situation. An example property is 3 units, Unit 1 (rent $1,800/mo) - 1bed/1bath, Units 2&3 (rent $2,600/mo each) 2bed/1baths. Purchase price $1,200,000 with 3.5% down FHA loan. Estimated PITI $9,000/mo.

Brother 1 would provide capital to down payment and for rehab

Brother 2 would live in Unit 2 & provide capital to down payment and for rehab

Brother 3 would provide capital to down payment and for rehab

Based on the above, how would you structure the equity % breakdown for this investment?  Should brother 2 pay market rent?
