I noticed their business is listed as an LLC on their Zillow profile, and we also found that they have a few other unrelated LLC businesses that didn’t seem to work out for them over the years and were short-lived.

A squatter can see it's listed for rent with a sign or without so I don't think that'd be a huge concern.

HOWEVER; if you aren't going to use your full last name, then it's important to upload a pic to your profile (which you have) The reason being, when someone has a common name, with an initial and you are trying to @mention them, if you have a list of 5 David R's with the stock icon, it's impossible to know which is the correct one. 

They list only either the opening bid for the property they are auctioning off ($50,000) or they don't list a number at all3.

You can simply list it as a $300k sale and list Seller Finance as one of the financing options in the MLS.

Would love to see some of those listings.

Go to AirBNB app and research which areas have the most listings, that usually means that its a HOT area and if you run it right you can succeed.  

Focus on areas with strong rental demand, like Broad Ripple, Fountain Square, or near universities like Butler and IUPUI.Maintenance Costs: Indiana weather can be tough on properties, so budget for seasonal maintenance like snow removal and HVAC servicing.Additional AdviceKeep an Emergency Fund: Unexpected repairs or vacancies can arise, so having 3-6 months of expenses saved will help you weather any surprises.Build a Reliable Team: I have lists of contractors, handymen, cleaners and property managers if you'd like me to send.Good luck with your property and future expansion!

Blue gate is not listed on their website.  

I wouldn't call any of the fees you listed above as extra.
