Hey guys, what would be right steps to go after contractor who stole my money and run away ?

My ML model then analyzes available property listings combined with market data (crime rates, appreciation trends, school scores, etc.) to recommend properties that align with the user’s goals — cash flow, growth, or safety.I’m trying to be extremely careful to ensure that my system does not cross any legal lines, especially with regard to Fair Housing laws or algorithmic bias concerns.While the model doesn’t discriminate on protected classes (race, gender, etc.), it does consider factors like crime rates, school quality, and local economics — all of which can indirectly overlap with sensitive social patterns.

An illegal unit is not legal because unpermitted work was completed, and the city was made aware, issuing a violation citation.  

You can try searching for a consumer rights' attorney in your state.Martindale.com or the Alabama State Bar Referral Service may be able to assist you.If you didn't know, there is a Facebook Group called, "Selene Finance Complaints."

Legal Separation Needs: (for any reason if other houses have a dispute or litigation with developer, is it impacting my constructions as well?)

You can try to do it manually and not mention anything related to sales, thus reduce the risk of anyone filing a complaint.

In this case, you should have an Architect / GC visit the space and tell you what it would take to make the basement "legal".

Is this something I should file a formal complaint or do anything other than tell him that I can't trust him and cut ties?

Quote from @Cheryl Abram: What legal filed docs are LPs entitled to see to help validate a deal's failure?

I wouldn't know anything about that.My biggest complaint is the excessive cost.
