With this deal, the biggest problem I can think of that can't be quantified on the spread sheet is budget over run.

Just way too much fraud, waste, and abuse to quantify. 

Trying to game the system with timing tricks is unlikely to yield you a result that you could quantify.

Part of the reason risk is not talked about as much as Return is because, unlike Return, Risk is hard to quantify and is subjective to each investor.Both Risk and Return form a framework which I use to make investment decisions.

This causes improper ideas to emerge and the reinforcement of improper ideas.We seem to measure or quantify the content of a given book or program by the amount of endorsements it receives.

Scott :) I have no way of quantify how many are after insurance work.

Engineer's main problem is not being able to make decisions while trying to quantify risk with some certainty.I wish you could buy a property with ZERO risk, but you can't. 

@Kevin Hill I've been following this post and thought I would weigh in on a couple points:There's been a lot of references to 'crazy low interest rates' but I thought it would help to quantify that for the newbies.

Once you get a few that see you're doing ok and show interest in RE, you can vaguely let them know that you have 'a couple more' properties, so they get an idea that you're expanding and still doing ok, but until they can talk to you like another investor, I see no reason to quantify a count of doors for them, because it's just too much for them.

This is a lot of money, which you need to quantify.
