What are the best lenders in the Chicagoland area?

[Angel Moreno]

I currently bought my first duplex I am house hacking. I have very little expenses, no debt, and make a decent income. I plan to save money to be able to do my first flip in 2023. Who are the best lenders in the Chicagoland area that work with house flippers and about how much cash will I have to save to be able to qualify for a loan on a fixer upper? 

Thank you in advance!
