Sch C expennses

Hello , 

LLC was set up as a  construction business in 2019( flipping houses). Mortgage was taken on my name and started remodeling. I will sell the house in 2020. Can I take all expenses that occurred in 2019 this year 2020( including car expenses and business launches). I did not have any income this year. I I take those w\expenses in 2019 on Schedule C can I take NOL carry over for 2020 taxes to lower my income from selling a house. 

Thank you
