Is Zillow a good place to get quick Comps?

[Todd Lawrence]

I am very new to all of this, and I was wondering, short of bugging a real estate agent (whom I just met) every 10-15 min about a property that I found online, is Zillow a good place to get a quick and easy (not to mention free) comp? For instance, I found a foreclosure for $25,000, went out to look at the property and from the outside, I could tell that there were no indications of foundation problems, could use new shingles (but no need for whole roof rebuild), new windows and probably air-conditioning repair(10-15,000). I looked though the windows (as Im sure everyone does) and the carpet looked in good condition and walls and ceilings looked clean and sturdy(10,000 est). I looked on Zillow and the neighboring houses were going for 65-70. Now at this point I got on the horn with my realtor and said set me up with a looksee and when I did, he told me that the property had already closed that day...never got a comp (well a real one anyway). Just wondering if this was the right thing to do, or was I headed up the proverbial creek with eyes wide shut. Thanks for your time and patience.
