@Abrahm Dimmitt,PropStream has a lot more data in it. 

The software steers you through most of the data entry.

It offers high accuracy with 80-90%+ correct contact data, which is crucial for reaching homeowners.

You should definately expect a good ROI, but I dont' have data to show how that would effect it would have on revenue.

There is quite a bit of data that home prices are starting to decline in many areas.

You can let the data decide if it's the right market for you. 

Then take that data and skip trace it for numbers email etc.

Maybe there's an angle for seller financing or some other creative approach to get the seller the total return they want over time, but it's hard to say without actual facts and data.

Luckily I am not easily sold on any ideas without some data to back the ideas.

There aren't many co-ops in Southern California, mostly in LA or a senior community in Orange County, but there's not much of a discount between condos and co-ops - at most, 10%.What is your source of the 10% difference data?
