Pretty much every property that I've tried to analyze becomes impossible to do so due to not being able to figure out everything that needs to be done.Ex: I can look at a picture and see that it needs a complete rehab, but I can't really measure the counter space to find out rough costs, or measure the flooring to do the same, or know what pipes are going to need to be replaced, or how much open square footage of wall space there is in the kitchen that needs to painted to calculate that.

I have told business partners before that I may suffer from a ready, fire, aim mentality, and I definitely lean towards the GSD mentality!

My typical approach is ready, fire, aim, but have been working on switching those last two pieces.

I know how to use AutoCad, so I will be able to take measurements and modify.

Aah okay, I was not sure what numbers were conservative, which is what I was aiming for.

About the market here: entry level places start around $500k in San Francisco and I'd be aiming for that ballpark.

Since CoCR is only measured during the first year, based on the initial cash you put into the deal, you should start measuring it immediately.Also, ROI is a mixture of actual profit and a variety of imaginary, hopeful financial gains. 

Personally, I aim for 2% and the closer the deal is to that, the more excited I get.

As investors we aim to make 10-12% net per year from a deal, where is the best area to concentrate on?

Going to be hard to answer this without more information - but a general goal post to aim for (I believe Brandon Turner does) is $100-$200 per month after ALL expenses per door.
