Access to "Sold" Property Price Data in Austin

[Matt Moeller]

I am a real estate salesperson in Houston looking at houses in the Austin market, but I am having trouble accessing the actual sales price on sold properties through my HAR.com (Houston Association of Realtors) portal. I can see active listings, but not the sales prices on the closed listings. Can someone in Austin let me know how I might go about gaining access to the historical MLS database of closed sales prices? Thanks!!!
