I wouldn't be giving that information out without an appointment guys! This is part of the reason some homeowners think it's easy to sell a house as a FSBO and then wonder why their house sits and sits or gets a low-ball offer from an investor. Just quoting PPSF doesn't tell you if the homes that sold had a fireplace, a bigger garage, sprinklers in the yard, wood flooring, granite counters, etc, etc.
Realtors get paid to help with transactions because they are supposed to be the expert in their area, not the used car salesman peddling broad information over the net.
Not all homes comp the same in a given radius, sometimes you have to broaden your reach and then the individual properties may require further look at tax information and county records to ensure it's apples to apples. Not to mention comps don't tell you everything you need to know about what's going on in the CURRENT market. Some parts of Austin are in a seller's market right now, but not all! I've seen some really great looking homes sit for over 90 days because they aren't staged right, over-priced and under marketed.
Unless your a real estate expert (Realtor, Broker, Savvy Real Estate Investor, etc), hire a realtor. Just my 2 cents.
