Mobile Home Flip - Where do I enter this?

Brock_626

We purchased a mobile home in February 2024 to flip and sell. We are still working on it now, as of March 2025, but should be done within the next couple of weeks. Do I need to enter this anywhere on my taxes for this year? We haven't made any money off of this yet, but we have spent a lot of money working on it. Would this be a schedule D or C? Do I report it on our 2024 taxes or just wait until we sell it and report it on our 2025 taxes?
