Having worked in and around real estate including loan side for both residential and smaller specialized commercial (medical), renovation and new construction/new build with a broker & brokerage founder (who has since retired) I know from him that in addition to reputable property managers, contractors and architects we had accountants including a forensic accountant on the loan side and a handful of real estate attorneys with one on retainer.

Should I get in touch with brokerage firm(Broker) about the agent's handling of this?
