Quote from @Account Closed: Honestly have no clue, but my guess would be contact a lawyer who specializes in real estate.I am also trying to get a hold of other wholesalers in my area and real estate agents.

Or does one need a special license / need to open a company?   

See what is possible thru Special Use or Variance permits.4. 

If anyone has listings or is a realtor that specializes in these types of properties, please reach out!

Supplement this far simpler entity approach by ensuring you have appropriate types and levels of insurance, you operate your business in a manner in which your conduct is not considered an exclusion in your policy, you work with licensed and insured vendors, you execute contracts with indemnification clauses with these same vendors/ require additional insured status &  maintain appropriate licensing and permits.

Another one I wish I had taken earlier was to get involved with a boutique or specialized commercial broker. 

If you just want to make some quick cash so you can supplement your retirement, then sell it and relax.

Does anyone know of a company specializing in cleaning commercial spaces?

My focus is on raising capital for acquisitions and acting as a general partner in real estate investments, with a special interest in industrial, multifamily, and retail properties.
