This definitely depends on where you are (I am assuming a larger state), but I will use Colorado for example because thats where I am. 

Have to agree with @David Barnett and @Mark Fries, if you are an investor you are a business person, i do not know your project and what is involved, but just your attitude in this post tells me i would not want to do work for you and would jack up my price pretty high if i knew i had to deal with you. part of the pricing difference goes into the "illegal" contractor, not a registered co with no insurance i am sure and no payroll to speak of, because any help he will have is paid in cash. there are costs to run a construction co and it is not cheap, just to step in your door on day one to start any work those costs can be as much as $500. i am not agreeing that $10,000 is a fair price, especially if it is just a shower, but you can not compare a licensed contractors price to someones price that just does not care to work legally.

I intend to use the LOC to pay for rehabilitation, down payment, and/or holding costs that will be necessary to buy, rehabilitate, and then immediately resell residential properties for profit in Colorado Springs, Colorado.

Purchase price: $1,150,000 Partnered up on a 1031 into a mid size commercial MF in Anchorage (16 units) - no further cash required due to 1031.

With that said, for my friends first flip he contacted a co-worker and was able to access money from the friends IRA. 

You also don't have to deal with deductible or co-insurance if your tenant's insurance pay for a small kitchen fire.

I think you may be referencing single family here, but my interest lies in mid size multi-family units so maybe you could give an example for: 1.
