Brandon. Congratulations you have taken the hardest step in this process. Which is starting. Awesome! I work am in the la crosse area I would love you to give you some advice if you would be interested in it. "motivated sellers" is a something that is a interesting thing/ niche to qualify. Using a data service isn't necessarily the way to find a motivated seller. people are motivated by many factors. If you are looking to "BRRRR" for a small multifamily it is something that is unlikely to pop up on a data service. Not saying that it is impossible just not very likely.
You can use keyword searches. check out of state property owners, code violations something that you can get from local governments, tax liens, pre foreclosure, variable rate loans when the interest rates are rising, properties that are interfamily transfers, water shut off list. properties that are owned for multiple years, owners that own multiple properties. Failed MLS listings these are things that I am finding some success with. These keywords are not the end all be all.
I personally use prop stream for my data service, however I am not the happiest with them in the la crosse market their data doesn't seem to update enough.
