We have worked with Johannes on and off for the past several years while looking for an investment/vacation home in the NE Mesa area. He has been incredibly responsive to all of our queries as well as patient with us while we figured out what we really want.
Johannes' background in architecture really helps him see and explain the potential (or lack thereof) of properties. We passed on several "good deals" that would have been problematic down the road. His depth of knowledge of the Phoenix metro marketplace is another valuable asset.
Once we found a home that we wanted he did a great job of negotiating a good deal and expertly managed the purchase process -- especially important since we were out of state.
In summary I highly recommend Johannes for your Phoenix Metro real estate needs.
