Has anyone had any luck obtaining legal counsel and fighting this?  

If you have specific questions about property management, I'll be happy to help!

If they had not moved out, i would have brought in the best attorney available and charged the tenant for the legal costs.  

While I haven’t chosen a specific niche yet, I’m leaning toward purchasing a multi-unit apartment where my 20-year-old son could live and help manage while we rent out the other units—essentially a form of house-hacking.So far, I’ve connected with a few real estate agents and gained MLS access, which has been a great starting point.

Ask specifically what is needed to comply. 

Most are fine with that, but a few will have problems with it and claim there are legal issues, etc..

Considering it's from a reputable auction site, do I have decent legal standing if they misrepresent it?

It's all about building trust and relationships, and in the long run, that will pay off way more than just trying to squezze a specific deal.

Would need to know a bit more before giving a specific direction but it is usually best to hang on to your property and not sell whether you expand on it or rent it out and purchase a bigger property.
