In so many ways, and in so many professions, success comes down to effective communication. That's because the way we communicate says more about how competent we are than external appearances. If you REALLY know you're stuff and communicate it well, then I think people will look past your age. It may not be fair, but I do think people look more closely at age when it comes to important transactions. If a person is too far to one end or the other of the age continuum then certain sterotype may come into play. For the very young, it's inexperience, imprudence and so forth; for the very old, it senescence, forgetfulness, etc. This is why I say you should REALLY know your stuff and communicate it well. Don't give people a chance to apply these stereotypes to you. Nip them in the bud by taking the focus off your age and placing it on the matter at hand, real estate.
