Access to public transportation is a key factor in may home buying decisions. The appeal of not needing a car or needing to rely on one for everyday use is very appealing. RMLS has both BUSLINE and LT-RAIL as search enabled fields (there is no streetcar field at this time). There are currently 870 listings in Portland with at least one of the fields listed. In 2015 Trimet will open a new light rail route from PSU to Milwaukie crossing the to-be-built multi-use transit bridge by OMSI (image from Trimet.org). It will cut across the river near where Cirque du Soleil sets up between the Marquam and Ross Island Bridges.
A part of the Sellwood Bridge replacement plan has provisions to revamp the west side on-ramp to accommodate extending the streetcar line from its current end point in the South Waterfront to Lake Oswego.
