GC is incompetent, has failed to get proper permits and has stalled on the balance of the work so seller just wants out.

My IRA is just a fail safe at this point and STRs are where wealth is built.

This person failed to pay the taxes for 2023, so I bought the tax lien.   

I just really hate this process:  2-3 years to foreclosure, then dormant REO, then investor rehab fail, then 2-3 years of tax default, then tax default auction.

As a 20-year industry veteran, I still see most sales agents fail to understand what I do (typically, they think they know).

For illustration purposes if a tenant or passerby trips and becomes  hurt because of a premises liability event, if you discriminate against a tenant or buyer, fail to pay your contractor for work that was performed or any of the many fact patterns that could lead to claim exposure presents itself do you really believe your identity is going to stop a plaintiffs attorney from filing a claim, lien etc?

You failed to mention that there are a lot of slimy landlords that try to intimidate tenants into leaving just days after accepting their rent and deposit.

There's a common belief that properties can "fail" inspections or appraisals or they certain loan products can't be used on distressed properties.

Does RK have any liability regarding this house if the buyer fails to pay? 

If you fail to follow the rules, you may open your personal assets to a lawsuit.
