Inaccurate Propstream data

Has anyone had recent problems with PropStream data? I use PropStream for list pulling and comps (mainly comps) and have found that in the least few months their system is providing wildly inaccruate data. And before I explain where the inaccuracies are, let me explain how I know they are inaccuracies and not just "lagging data." I asked Propstream directly, and they said records of sales are pulled from the county level and updated DAILY. But this has proved false, and when running comps, this is a big deal. 

I'm finding when I look at a given property, I get inaccurate comps in two ways: 1st, a property will show up in the list as a comp to my subject property but have a REALLY low sale value; upon investigation I find that the property acutally hasn't sold in 10+ years but PropStream thought it was comp; 2nd, a property will show up as "Sold" in the MLS status, but all ownership and transaction history tab don't reflect the new data. And yes, I checked county records and the county DOES show updated data. And we're talking sales MONTHS old.

Obviously, if I'm trying to comp a property and Propstream gives me stuff with sold prices and ARV's from 10 years ago, that doesn't give good comps. And if houses are showing an owner having been there for 10+ years when that owner actually sold 8 months ago, then I might market to a completely unqualified lead.

I'll post a link to ONE example of many I've found recently, along with one to county records for refernce. Propstream shows old owner. An investor bought this in February of '24, and flipped and sold in July of '24. County records updated, Propstream did not.

    We use propstream and have found their valuations are always all over the place and take them with a grain of salt, but will look at the sales in the area/neighborhood. While i state this, i also had a licensed appraiser just give me an appraisal that was a complete joke. The best way to gauge value is to do it yourself based on reviewing comps taht were sold and condition and come up with your own number is what I have found.

     @Chris Seveney I always take their valuations with a grain of salt, but we're not even talkin valuations. Their sales data is wrong. I can gauge my own evaluation by looking at recently sold comps, their condition, exact location, etc. But if they are showing properties that haven't actually sold recently, or not reflecting recent sold data, then that's a problem and will throw off my own evaluation process.

     yes that is a bigger problem for sure. I have not run into that yet, have you contacted them to share with them this misinformation? Typically companies like this actually want stuff like this reported so they can see if its a bug or what is going on with their system.

    @Jonathan Boyd Hi Jonathan, do you have an idea where propstream gets it data from directly?
