Some general factors that may impact the advantages and disadvantages of buying property in any location, including Sammamish:

Advantages:

1. Proximity to amenities: Sammamish is close to major Seattle job centers, excellent schools, and recreational opportunities, including parks, hiking trails, and lakes.

2. Increasing property values: Sammamish's property values have appreciated at levels higher than the national average over recent years due to the city's growing demand and robust economy.

3. High standard of living: Sammamish is known for its high standard of living with low crime rates, high ranking school districts, and plenty of community services and events.

Disadvantages:

1. High cost of living: Housing costs are higher in Sammamish than in many other suburban areas, which may put homeownership out of reach for some buyers.

2. Traffic Congestion: Despite its proximity to Seattle, Sammamish is still quite suburban, and as growth continues, traffic congestion may become more of a concern.

3. Weather: Summers in Sammamish tend to be sunny and mild, but winters are rainy, and the area is at risk for natural disasters, such as earthquakes.
