So I've been using Propstream for about 2 months now - the software works well enough for what I need it for, here's my breakdown on the good and the bad:
Good:
1) Comps - it auto generates potential comps for you and then you can sift through them to find which ones you want to use and which ones you don't.
2) Analysis packets - I work with a lot of investors, and the analysis packets that you can put together in Propstream are thorough. You have to be really careful to input the right numbers (garbage in = garbage out), but if done correctly it will give you a very solid analysis on a property.
Bad:
1) MLS and property owner data is not up to date - I called Propstream support and they said that MLS data is updated every 48 hours, but I've seen properties up on the MLS for up to a week before they hit Propstream. Property owner data is alright for the most part, but there are some properties that have been sold 6 months - 1 year ago but still have the previous owner's information as current. I typically will cross reference tax records before reaching out to an owner to verify, and that has worked well.
2) Not a very intuitive platform - It's doable to figure out, but it takes some time to get used to the system. Plan on spending anywhere from 5-10 hours watching youtube tutorials to try to figure out the ins and outs of the system. This is not necessarily bad, as the software is capable of a lot, but it does mean that it will take some time to get used to.
I hope this is helpful! I'm going to give Propstream another couple of months and then I may switch over to REIpro to try it out. Feel free to message me if you have any questions about Propstream!
