Connecting House Points to City Street Network

Im currently trying to set up a network that includes points representing properties (houses), polylines representing roads/streets, and polylines representing rail stations. The problem is that a significant amount of the 300,000 properties aren't connected to the road network. Im looking for a way to add connecting lines where necessary from properties to streets and set an attribute on these drawn connections to approximate walking time.

Is there a way to do this leaving the original road network unaffected? The snapping tools I have tried seem to distort the road network significantly since some of the properties are over 100 meters from a road. These tools also seem to just extend roads, so I can't set a attribute for travel time on these extensions.

Any help, suggestions, resources would be greatly appreciated!
