The Process

EVALUATION

We begin every assignment with a rigorous, data-driven valuation process. Our team leverages proprietary market intelligence, real-time rent and sales data, and investor underwriting benchmarks to determine an accurate pricing range and optimal go-to-market strategy. We analyze the property’s rent roll, expense structure, and value-add potential to clearly define its investment story and identify the key drivers that will attract buyers. From there, we advise on pricing and structure designed to generate strong demand and competitive offers.

The Process

PREPARATION & EDUCATION

Before launching to market, we collaborate closely with ownership to align on goals, timeline, and transaction priorities. We organize and analyze all property financials, leases, and operating data to ensure buyers receive a clear, transparent view of performance. Our team develops a professional, institutional-quality marketing package that highlights the property’s strengths, location, and future upside. We also recommend small, strategic pre-sale steps — from operational adjustments to data presentation improvements — that can materially enhance buyer confidence and pricing.

The Process

MARKETING

Our marketing approach is built around precision and reach. We leverage 33 Realty’s proprietary database of active multifamily investors — including private buyers, regional operators, 1031 exchange groups, and select institutional capital — to immediately place your property in front of qualified decision-makers. A multi-channel campaign combines targeted email outreach, curated investor calls, and strategic digital exposure supported by data-driven market insights. We host private property tours and investor meetings that showcase the asset’s fundamentals and upside, then manage a structured, competitive bidding process designed to maximize both price and terms.

The Process

TRANSACTION MANAGEMENT

From contract to close, we handle every detail. Our team coordinates buyer due diligence — including inspections, financial audits, and third-party reporting — to keep deals moving forward without delay. We lead negotiation of the purchase and sale agreement to protect ownership’s interests while maintaining transaction momentum. Throughout the process, we manage communication between all parties — buyers, attorneys, lenders, and title companies — and oversee every milestone through a successful closing. The result: a seamless transaction and optimal outcome for our clients.
