What tools or processes have you implemented to estimate rehab costs more accurately and avoid scope creep in BRRRR projects?

And yes, that's a rather accurate measure. 

Having worked in corporate architecture firm for 13 yrs before opening my own firm, I understand your basis @Jay Hinrichs and it's totally accurate.

Many of the BP calculators want you to put in 5% but this is not always accurate.

I have been practicing my deal analysis daily, but it's hard to tell if my numbers are accurate without comps. 

If it is very rural having contractors and completing on time and accurate numbers can be challenging.

If it is a breach of contract to do such action, no, it's not true or accurate to say a person "can" do that anymore than it is to say a person "can" rob a bank.

While you present a very interesting response (not accurate of course, but interesting)I'm not aware of a case where the judge dismissed the case because the defendant stated "I didn't know it was illegal"This is no longer for you.

Wells Fargo ultimately turned me down because my specialist was completely clueless in general, and because she failed to accurately relay what I was telling her to her "internal contact" on the phone. 

It's a gamble either way.
