I tried to use an app called melio to pay some of my contractors with a credit card and it cost me more headache than planning for my rehab project.

If you have cash on hand to fund the rehab and want to extract it soon after the project is done, you can use delayed financing.

I'm looking to finance the project long term in a way that is helps me create positive cashflow.

Has anyone done such a project before?

Investing in single-family residence fix-and-flip projects in New York involves purchasing distressed or undervalued single-family homes, renovating them, and selling them at a profit.

- Most real estate investing projects have negative cashflow for the first few months - if not the first few years.Keep listening to the podcasts, but pay attention to WHEN THEY WERE RECORDED!

This one was strange because I ended up splitting the companies and partners involved in the deal so we liquidated halfway through the project. 

The best projects I've seen from my desk are folks who are doing hyper-targeted, well-researched deals that are generally in higher cost of living (there are exceptions) areas. 

I only charge markup on maintenance if it's a larger project that requires more coordination, supervision of the work, and inspection after completion.

It's very hard to say if a 50/50 cash flow split is good without seeing the numbers for the project.
