ABOUT THE ROLE

The Brokerage Sales Team owns client growth across acquisitions, dispositions, bulk syndication, and transactions title & escrow. We compete with national tech-enabled brokerages, institutional-focused platforms, and local operators. Our goal is simple: be the first call for every serious SFR investor transacting at scale.

As a Senior Brokerage Sales Associate, you aren’t just a salesperson - you are a trusted advisor to institutional and scaled SFR operators. You will sit at the intersection of strategy, data, and execution, leveraging Mainstay’s technology to deliver differentiated outcomes for our clients.

IN THIS ROLE YOU WILL

• Pitch and onboard new institutional clients onto Mainstay’s transaction platform while aggressively expanding our “share of wallet” within existing accounts

• Use portfolio and market insights to proactively identify acquisition and disposition opportunities for your clients

• Manage disposition strategy for institutional SFR and REO/bank-owned assets, coordinating with servicers and asset managers to optimize pricing, timeline, and bulk sale execution

• Serve as the primary escalation point for complex, in-flight deal issues, maintaining composure and sound judgment under pressure

• Act as the voice of the client, influencing our Product and Data Science teams to improve our platform based on frontline feedback

• Translate complex data sets into actionable insights using Excel and Slides to drive client decision-making

WHAT WE’RE LOOKING FOR

• 5+ years of experience in SFR brokerage, institutional residential real estate, or a closely related transaction sales role (ex. Financial sales & trading, commercial RE brokerage, appraisal/valuation, title, commodities/freight, etc.)

• Proven track record of managing and growing relationships with sophisticated, scaled operators

• Hands on experience with REO/bank-owned property disposition, including servicer and asset management workflows, BPOs, and bulk REO sales processes

• Advanced excel modeling skills and the “data fluency” to draw strategic conclusions from raw information

• Ability to collaborate with and influence internal Operations, Product, and Data Science teams

• Exceptional presentation skills and the charisma to maintain frequent, high-value touchpoints with senior clients

• Ability to travel up to 33% of the time

BONUS POINTS

• Experience working at or with tech-enabled brokerages or platforms

• Existing relationships with bank/servicer asset management teams, or familiarity with servicer platforms (e.g. Res.Net http://Res.Net, Equator, Pyramid, REOTrans)

• Data fluency to work with Claude, Hex, etc on data analysis (prior SQL experience helpful)

THIS ROLE IS A GREAT FIT IF:

• You focus on building deep, long-term institutional relationships and have the charisma to become the first call a client makes when they have a strategic problem

• You are highly “data fluent” and enjoy using AI, Excel and Slides to translate complex market insights into actionable advice that influences client decision-making

• You remain calm and use sound judgment when deal flows get messy, effectively navigating complex escalations without losing the client’s trust

• Y
