Platforms like Zillow or Redfin can give you insight into comparable properties, and PropStream is great for deeper analysis like liens or ownership history. 

BTW - Are you using both platforms?

Do you know of any websites or platforms where I could go to analyze and practice seller finance and creative finance deals?

Propstream - Data creation + stackingDeal Machine - Driving for DollarsOpen Letter Marketing - Mail ProviderUsing these 3 platforms, you will be able to create lists, research properties, and market to them effectively.

The challenge I found is that with real estate it seems to be much more complicated than giving people encouragement and cheering for exercising.. 

I’m curious to hear if people have done this in the past, how they did it, how they started, etc.Any thoughts / discussion / enlightenment on this is encouraged!

Looking forward to get more familiar with the platform 

This is the best platform as a starting point. 

My top priority is having maximum flexibility with what I can invest in within my HSA, second priority is ease of use and convenience of the investing platform, third is minimizing any account, trading, or management fees charged by the HSA provider. 

I encourage you to dive deep into forums, listen to podcasts, and connect with like-minded individuals.
