Crash coarse on analyzing rehab costs

[Levin Angeles]

My wife and I are new investors looking for our first break. We had wanted to get more educated and gather more information before we got to this point but right across the street from us, a potentially good deal just opened up.

We just came back from seeing the property and it looks like it needs everything done.  Can anyone point me to the best way for me to quickly breakdown the costs for rehab?  I'm already familiar with the price ranges of the neighborhood since I live here and the asking price is already low enough that I think I can renovate with a healthy profit but I'd like to breakdown the costs item by item to better analyze the deal.

There's already multiple offers for the property and even if I don't get the deal I'd rest better knowing I didn't passively give up just because I didn't try my best with getting even a conservative offer on the table.

Thanks for any help.
