I represent Landlord in shopping center with multiple tenants. 

Title insurance does not represent the status of title to real property, and an insured cannot rely on the title policy to represent the title.

I had a call with an accounting firm this morning and he mentioned something like he is not a CPA so he is not able to represent like CPA.What does it mean?

Its a no brainer that you are right and the other party is wrong, yet, you still higher an attorney to represent you.

I would also say that markets like Manhattan are not super representative of most markets in the US - a lot of foreign investment I'd imagine in NYC, Miami etc - I'd guess a lot of these cash purchases are more about exchanging unstable or risky foreign assets/currencies for perceived stability/safety of US top metro residential real estateI think in a lot of other markets where this isn't relevant - I think most are cash offers being "king" as not having appraisal or other contingencies that might sabotage the sale after 30 days or so and make people re-list (sellers will take less to avoid this risk and downside)

I'm a partner in an Independent Agency that represents Steadily along with many other companies. 

And this is from a broker often representing a very well qualified and interested buyer of their property.

Whoever represented you really let you down, you could try suing them if they are a licensed professional.

Are you representing yourself as a Registered Agent and if so is your personal address listed?

I would also reach out to agents who have represented buyers in more expensive markets.
