@Nick Fitzpatrick thanks for the speedy reply! You touched a some points that I'm currently in the process of researching, so I appreciate your insights.
I need to do more research, but I believe some HML, like Lendinghome, have an option for draw requests, but I have to ask more questions to be 100% certain. Also, we're looking into contractors who are willing to work with renovation loans and will, hopefully, take payment directly from the lender at the time of draw. I recently learned that LOWES offers whole home renovation services, and after talking with a project manager we learned that they will accept payments at the time of draw. So that's one plus, but I think we may need other contractors, so we're working on that piece of the equation. In Chicago, it's common for contractors to work this way, but I'm not sure how that works here in ATL.
Do you have any recommendations for lenders who specialize in renovation loans, or other reputable HMLs?
