It helps you learn to spot the "diamonds" yourself.I understand the economics of why real-estate agents can't really take every investor to a hundred properties, but looking at lots of properties (especially with an experienced agent pointing out the benefits & flaws) can help you decide where and what to buy.

If you haven't already attended a local REI event, I would highly recommend you go to the Black Diamond event next week, the local AREIA's and you're welcome to attend my next Unofficial BiggerPockets Networking Event in December.

But good ones are like diamonds among the ore

Over 1,000 sq. ft. with wood-burning fireplace, private deck and garage parking just down the hill from Diamond Peak Ski Resort & within 1 mi. to golfing, Casino & private beach! 

You might take advantage of the MA attorneys who regularly attend our Black Diamond events and discuss these questions at the meetings during networking before and after the meeting.

Most of them aren't very experienced, but sometimes they will find a diamond in the rough.

I have my eye on a piece of property that’s a real diamond in the rough but it’s already listed on the market.

Way to see the diamond through the rough! 

That should be an altogether comforting thought regarding their perspicacity in rejecting you.Working in the sun with no tent...do you still have both your hands, or are you picking through mud beds with only one to find blood diamonds while the overseer looks on with his machete ready?

Quote from @Kathy Diamond: @Tim Delaney just confirming here: buyer brings inspector to look at the property to gauge how much work needs to be done.
