Is partnering to cash buy, flip and sell, repeat a good strategy?

[Huzaifa Ahmad]

New to real estate investing and trying to avoid using leverage/loans involving interest due to religious reasons. My wife and I have another married couple friends in the same boat and we thought let's partner and pool money to cash buy and then flip a house, start off cheap like a $100,000 house, flip and sell and use profits to buy a $200,000 house, repeat and rinse until we can afford a 4 unit multifamily to rent out. Ultimately goal is to generate passive income through cash flowing properties without using interest loans. Does this seem reasonable or is there a better strategy with creative financing that does not depend on loans? Thanks!
