In this method the profit should be calculated only according to the investment of each person, i.e. the person who put 50,000 gets 50% of the profit and the other 2 get 25,000 of the profit.There is a third option that is the combination of the other 2 options that is to make a percentage of the money of the bank as it was equally belonged to each partner and the other part according to the percentage of each one invested.Thank you for reading.Your answer might be really helpful for us.

If I was making this post a few years back, I would certainly be leaning towards the House Hacking method, but I don't think she'd go for living in a duplex/triplex with other tenants, and considering we have two Australian Shepherds.Anyway, this is where my head is at for our first strategy: Buying our first live-in home as a fixer-upper and kinda/sorta implementing the BRRRR strategy. 

Is anyone currently practicing this method in this area?

Are you using cash for keys or any other methods for tenants with expired leases to prevent delays with holdover filings?

I just prefer the option method.
