I am also a resident of SEH and can give advice. Questhaven is busy so consider the noise in your decision to live there. For rental purposes, it wont matter. The stop sign/ four way intersection is dangerous as many people blow right through it but you would be in proximity to the park. I assume you are off questhaven and not off wild cat canyon right?
I cant speak to the condos but with a family of 5, that may be tight.
Edit – I assume its the house on old glen. Also, consider your proximity to schools. San Elijo elementary is overcrowded but you can walk to the school assuming you are in SEH boundaries. Try to walk to SEH because pickup and dropoff blows. The new school double peak is in demand but is delayed until August 2016 (which works for your kid going into K). The school will be K-8 which is nice if you want to keep all of your kids in the same school together and its supposed to be rock solid from a technology perspective. Getting the kids there will stink but hopefully a solution comes to light for that (like buses for the district).
