Quote from @Michael Brzozowski: If you need renovations once you decide on something, im contractor currently looking for investors to work with:) I will keep this in mind.

Fortunately, they should and usually do have local contractors in the area that they turn to for maintenance. 

In my shoes, it would be hard to credit a client for a decision that could have saved you $10k+ in damages, especially when it wasn't something that went to our firm (like management fees or an in-house maintenance contractor).

Also, juggling multiple rehabs often means building a core team of reliable contractors and setting firm project timelines.

I also have great contractors that are familiar with what prices are.I guess all in all it boils down to experience.

Contact a couple contractors to see what the cost would be to add the addition.

No, none of my contractors were labeled/considered to be corporations.

I can come up with money for flips and have a contractor I have been talking to for the work.

That might be our only true recourse.I don't know what State you're in or if you used a builder contract or the standard State contract form.

My partners & I are flipping in Chattanooga so I hung out there for a couple of days, meeting my contractor and agent for the first time; of course I went by and took at our flip.
