The platform's main focus is processing mortgage documents in their raw form to extract specific financing terms for all properties in the city.

It sounds like you / your parents should just hire a professional property manager for the inherited properties.  

For example Delaware has additional default rights and processes that an investor can follow if they feel they are not getting old books and records.

Quote from @Tyler Kesling: Not to drag this thread out indefinitely but if I were to take your advice and start small, is it the dumbest thing to 1) Hire a PM on a single fourplex and 2) Do a HELOC into a DSCR?

Could you explain that process?

You could then complete the construction and build your primary where you want on the land.It's a bit of a complicated process. 

I’m also in the process of launching a new home inspection company, which I’m confident will help me get back on track financially.

I would suggest giving it up and just hire an agent when you are ready to transact in the future.

@Ryan Bono Sounds like you've built a sweet team and process!

If you just hire the cheapest or first PMC you speak with and it turns into a bad experience, please don’t assume ALL PMC’s are bad and start trashing PMC’s in general.
