The Customer Experience

My team and I cover every aspect of the residential real estate process. Our listings have maximum exposure and our buyers are guided carefully throughout the purchase process.

Queenston Realty’s place in the Princeton Market is unique with the goal of offering and delivering real estate brokerage services through a concierge style approach for all your real estate needs.

Each transaction seamless and quick. She is the best!!!

Ingela is truly the very best realtor in New Jersey! Her professionalism, great attitude, keenness, and powerful negotiators skills make her the best in this field. She listens and delivers! We closed in less than 14 days. She is the best!!!

We couldn’t have found our dream house without Ingela.

Ingela is the best! We started our house hunting with Ingela and we were glad we have her on our team. She always provided valuable professional inputs to help us make various decisions and pulled in useful contacts when needed.

Ingela was recommended to me by multiple colleagues, I see why.

The lesson I learned is that Ingela can do the impossible. A perfect choice for an agent. Solid five stars. I would use Ingela again without a moment of hesitation and recommend her to friends.
