This property also launched my short-term rental journey, running our first Airbnb before transitioning it to a steady cash-flowing rental, allowing us to scale into bigger projects.

I wish you well in your project. 

What happens if the roof has to be replaced?

Draws are almost always held back until you reach certain points in the project or that work is completed.

if your projects were profitable, why not find other investors and pay them the loan and move on? 

If you truly are limited on time or can't make investing a priority, you should look for smaller projects as others have recommended.1) General Contractors are available to run your project, but most are too expensive to make ROI work on smaller projects. 2) A great PMC can act as a Project Coordinator for rehabs, but many won't be transparent about the costs, so you know what you are paying for.

Permitted or not, you want 100% assurance the property is within building code standards for the year it was built, and for any upgrades/ changes - the years those upgrades were made; ie GFICs in wet areas currently, but not required in original construction back in 1950 when they didn't exist.sorry for not replying earlier, I'm rarely on this platformbest of luck on the project

He used to be great from the beginning of the projects.

You can also seek projects through licensed Portals that are using Title III and can accept money from non-accredited investors. 

Look for properties with updated roofs, electrical, and plumbing.
