Are the houses close together, OP? If so, I would say there are two strikes.
Is the street busy? Is it a cut through neighborhood? We are looking now, and paying close attention to whether the streets go through, from anywhere. Which would mean serious traffic, especially at rush or school hour!
Are there sidewalks? Not part of your actual question, but something else that has come up from our current search.
Any of these are definite deal breakers for me. I'm buying a house, not an apartment.
Plus, I would not want "two front yards", and limited options for the property down the line; including limited resale, if I tired of it.
