Why Untapped Home Potential for home buyers?

There are so many different things you could use the CityStructure Reports to market a property, like showing the possible ADUs, additions, potential to split the lot. The Report gave me all these options to attract buyers targeting different things. Of course, they still have to check with the city. Still, with CityStructure Reports I was able to inform a larger pool of buyers. I'm so, so happy..."

Why Realtors use Development Potential Report
to show the listings' opportunity?

We were a little hesitant to order the report when our Realtor suggested it. It was something new and we didn't realize how much it helped us understand the possibilities of our new property. We knew we needed more room. Now we're so glad that we purchased the CityStructure Report because we don't feel overwhelmed anymore about moving forward with our improvement project. Now, we feel ready!

Why Untapped Home Potential for homeowners?

Thank you so much! It was great having you at the open house today. It was a huge added value!! The CityStructure Report with its conceptual renderings was useful in helping us, as agents to position and sell build-out properties to our clients. The information in the Reports and the presentation boards were invaluable!
