Looking at properties and getting estimates

[Charles Sawyer]

Hey guys, quick question. Im planning to start looking at homes to flip soon (first one tomorrow). Since I dont have experience estimating rehab costs, should I have my contractor meet me at the property when the agent shows it too me? This seems like the only logical time to have him there to get an estimate so I can work the numbers and place an offer quickly. I cant imagine that many contractors would be willing to do this that often if I am looking at at large number of properties. But if there isnt one there, how the heck can I learn about estimating?! Is the solution to pay a contractor to walk the houses with me until I get the experience?  Seems costly for a newbie with no money, but I dont see another way. Please tell me I'm missing something.
