Realtor - Field of Specialization Designations ???

[Jessica Martin]

Im wondering if some realtors/brokers or other knowledgeable people can give me some advice on something...

Im taking online classes now to get my license. The site offers "specializations" courses such as:

C.F.S. - Certified Financing Specialist

C.P.S. - Certified Property Management Specialist

C.S.S. - Certified Seniors Specialist

C.T.S. - Certified Technology Specialist

Are these specializations widely known about by other professionals and/or potential clients and truly helpful in gaining more clients and advancing your career, or is this something that only this website offers that no one will really know what they are? 

One Specialty came with the package I bought, so I chose C.F.S, but if it is truely helpful to me I will purchase the other specialty courses as well. 

Thank you!
