Has anyone worked with them before and can shed a little more insight into how they work and operate? 

I'd love to get my feet on the ground and be in the rooms with people putting in the work and doing deals! 

Unless the property needs work and the seller is desperate, you're not going to find a seller willing to do any sort of seller financing on their end. 

Hiring someone to do the work will likely cost too much (I would charge a small fortune, it's an incredible amount of work) and doing things as cheaply as possible will bite you in the *** later when you start having issues with your own shoddy work and/or materials.

If I didnt monitor and didnt correct mistakes the job would've cost me the same but with lower quality work and craftsmanship

Below is my estimated scope of work and timeline.

There’s no shortcut to experience, but you can accelerate your learning by leveraging other people’s experiences.One of the best ways to do that is by attending meetups.

It’s a solid way to leverage equity, but as with any financing, make sure the numbers work and you’re comfortable with the risk.

Most of them just hire a key employee to run the technical work. And

In other words, I think that a lot of people look for shortcuts - or at the very least look for convenience.
