@Chris Seveney: You seem to be fair minded and I beleive you are not an agent.

Fair question. 

Then, there is an adjustment for the tenant's income and finally an adjustment for the area Fair Market Rent.

What do you want out of a GC:  Someone who has lots of quality sub connections, someone who doesn't soak you with their fee on top of Sub costs, someone who will be there to oversee manage the quality and speed of your project at least 3x per week and be in constant communication through calls and pictures. 

I came across a fairly creative deal. 

However save every single communication you have with them.

That changes the math a fair bit.I'd also be shocked if anyone is insuring this for $65/mo.

I love the fair and consistent style of communicating around this.

Fairly consistent rents for properties spanning realistically in the 100-250 range, with a healthy mix of SFH and MFH.  

A significant challenge was managing the renovation process while ensuring minimal disruption to existing tenants, which required careful planning and communication.
