How to file investment losses on an investment house flip? No profit made just a loss on the property, part of a group and I paid upfront and also made monthly payments.

I invested my own personal money, no LLC. Was part of an investment group where we pooled money, bought and flipped a house, paid upfront investment and monthly loan and utility payments and then we were cut out by the main investment holder. Can I claim the upfront investment and monthly costs and if so how?
