Information about the areas covered by Regional MLS (RMLS)

The RMLS Corporate office is based in Portland, although they have many other regional offices across Oregon and Southern Washington. The U.S. Office of Management and Budget identifies Portland as the principal city of the Portland-Vancouver-Hillsboro, OR-WA Metropolitan Statistical Area. The dual-state MSA is home to about 2,753,168 people, which makes up around 47% of Oregon’s population. The area’s highest peak is Mount Hood, rising to 11,239 feet, and the lowest point is the Pacific Ocean. 

Portland is known and loved for its progressive culture and vibrant city life. The city’s reputation for “counterculture” has made it a hotspot for those looking to jump into a progressive city with diverse groups of people. Portland has been frequently named one of the greenest cities in the world. The arts and music scene in Portland is unmatched, with countless museums, galleries, breweries, and theatres to enjoy. Several news outlets have also declared Portland to be the best city in the world for street food, with over 600 licensed food carts to choose from. 

Just a hop across the state line, Seattle continues to be one of the fastest-growing major cities in the United States. The seaport city offers a thriving economy, with several companies in the aircraft and tech industries. Seattle holds several annual events and festivals celebrating everything from anime to film to LGBTQ+ rights. The city provides a bustling and noteworthy music scene, with plenty of jazz nightclubs and theatres lining the streets. Iconic artists such as Ray Charles, Jimi Hendrix, Nirvana, and the Foo Fighters all got their start in the city of Seattle.

The OR-WA Metropolitan Statistical Area has a climate of cold and wet winters and relatively dry summers. The average high temperatures range from 74°F to 81°F, and the average low temperature falls to around 37°F. While the summers have minimal rainfall, winters bring an average of 18 days of rainfall per month. The average amount of snowfall typically reaches around 1.7 inches per season.

Who's winning with Showcase IDX?

Don't Just Take Our Word For It


Would You Bet Your Business On A IDX Solution?

We effectively compete every day with Zillow, Trulia and Redfin. Showcase Idx is critical to our success...Our site stats are over 12K unique users per week. That is up significantly from a year ago when we were on Wolfnet Idx.


What I have been looking for all along.

I have used both Diverse Solutions and IhomeFinder. Neither delivered what I wanted. Since switching to Showcase, my bounce rate is down 20%, time spent on my site has doubled, and most importantly I am getting 4x more registrations on my site.



Since switching to Showcase, registrations and customer interaction have increased tremendously. Showcase is so much cleaner than just using our own MLS systems...easy to use even for a beginner starting their own website.

Joshua Jarvis Owner, 4rd Marketing

Your retention rate will be much higher

No subdomains or Iframes is probably my favorite feature, but at the end of the day it's about Results. I think the biggest thing is how "sticky" their site becomes. With Showcase IDX, the retention rate is much higher.


I switched from IDX Broker

I get more voluntary sign ups than I did with old provider. I think that speaks for itself.


Showcase IDX all day everyday!

by far the best IDX solution out there. Forward thinking, always improving, with a clear focus on the interface - one of the major areas other providers fail. It feels like everyone else is still playing catch-up all these years later.

Charles Oreve CEO, The X Concept

Best IDX Solution out there

No solution even compares with what Showcase IDX offer. There is no way I would steer clients towards any other solution.

Nelson Cuesta CEO, AgentFire

Best WordPress IDX, period.

Simple to use (i.e. low bounce rates and high user engagement), great mapping with polygon search, fantastic mobile responsive functionality, ‘login with facebook’, ultra-fast, and they are always adding or updating functionalities.


The Best All-Around IDX For Realtors Wanting Results

We were previously using another IDX for our client sites. As a digital agency focused on measurable results, we were frustrated with the limitations we had. We started researching alternatives and thank god we found Showcase IDX.


Head and shoulders above the rest, and it's really not even close.

Showcase IDX is head and shoulders above the rest, and it's really not even close. We fully expect more of the agents and brokers we work with to love the value and flexibility Showcase IDX provides, especially as results our current users are seeing continue to improve.


An IDX Feed That's Above The Rest!

Showcase IDX is a better solution in regards to search rankings. I love the hot sheets and the simplicity to create "hot sheets" for different areas.


Converts website leads at a high level

Showcase IDX is leading the way in the world of WordPress IDX solutions. Clients love utilizing the Showcase IDX product with original features not found in any other product.


Best IDX plugin by far!

Showcase IDX is now the only IDX I recommend to my clients. Visually, it is stunning and so much better than the other IDX’s. To top it off, customer service is top notch


Showcase IDX Support Team Rocks

Showcase IDX has a streamlined interface and easy to navigate features that don't clutter our website or lock us into particular themes. But where they really shine is in their customer service.

Bill McCue Broker Associate

Showcase IDX brings the leads!

I am very happy to say Showcase IDX delivers the leads! I am often told by prospects and clients that our website is their favorite in town. A large amount of business is generated through our website presence.
