Technically that is not correct, and could bite us in the butt, but I haven't had to fight it yet....After they vacate the property, within 45 days, you need to send them a final accounting of the damages, cleaning, etc and how their security deposit was applied..

Our securities attorney is working through this right now.The good news is that we'll be offering a SaaS service for principals to use our technology soon.  

In the past, it wasn't worth dealing with an aggressive tenant, so I just waited it out (after experiencing enough loss of sleep).What you might consider is offering the tenant a portion of their security deposit back on the day they hand over the keys (if there's no damage) instead of making them wait, in exchange for cooperation in showing the unit.

I kept getting denied so I got a secured credit card.

Which in theory you can do whatever you want with - but the investor won't have their asset secured by real estate.  

Is there a product available to LLCs that’s very similar to a HELOC, that is secured against the asset, but doesn’t have extreme costs like hard money, typical portfolio loans for flippers, etc.?

Congratulations on securing your first flip.

What I need is someone to inspect the property and report on its condition, secure the property, maintain the property, and oversee any work required to get it into saleable or rentable condition.

I love that Idea by the way.I think CF is going to change everything and we have no idea what the end result will be or the ramifications in Mortgage, Real Estate, Securities, the list goes on and on.  

Since most of my properties are purchased in a distressed state of some sort, My first step is usually to secure the property and then start the trash out process.
