If you pay the GC his or her regular invoiced price for labor, materials and overhead, then the GC's equity share should be zero because the GC is receiving full pay in exchange for its service.  

It's very simple, sooooo dang simple vs any/every other industry I ever have or do "play" in.

And not a 1 of us LEGIT GC's will run around to pickup items you ordered, for among many reasons, were too dang busy running the circus; checking on jobs, designing job's, meeting with inspectors, running a project schedule, trouble shooting, meeting with suppliers, negotiating contracts, holding sub's accountable, vet'ing sub's, hiring, firing, all the everything that goes into making your project build possible that you don't see.   

Dang...sorry to hear this.

Too dang much trouble to change to something else though. 

My opinion is this (formed from personal experience investing in just about every way possible - house flips, wholesaling, short term rentals, long term rentals, new construction, NN commercial, NNN commercial)The most passive way to invest in real estate is buying a NNN property and outsourcing the administrative work (invoicing the tenant, paying the tax bill, etc).

Here's the lowdown:Time Logs and Calendars: Keep a record of your work hours in the real property game, it'll come in handy in the unlikely event of an audit.Contracts and Invoices: Hold onto those contracts and invoices like they're gold.

I guess my goals are pretty dang low by these standards.

Just ask for the invoice from the repair company, assuming you are requiring them to use a licensed and insured contractor.

Given that the "buyer" entered into a contract that he knew he could not perform to, there seems to be a viable claim for fraud.The attorney is going to invoice for his time.
