B. Quentin Foster | Principal Broker
B. Quentin Foster is a net lease acquisition strategist with more than 25 years of experience and hundreds of millions in asset transactions as broker and principal. In recognition of his contribution to the industry, Foster was named a 2025 GlobeSt. Influencer in Net Lease.
Through NNNBuyside, Foster represents buyers exclusively in the acquisition of triple-net, NNN/STNL properties and DSTs. He works closely with each client to define what a great deal means for them: their goals, risk profile, location preferences, tenant credit, lease structure, remaining term, financing, 1031, and exit structure. His approach is grounded in the reality that every buyer has a different set of parameters.
Foster’s background includes creating the first CRE investment MLS, Broker Investment Guide in Newport Beach, developing CoStar Exchange, CoStar Group’s first investment property MLS platform, and Net-Trade, the first MLS solely for Net Lease Assets. That combination of brokerage experience and market database expertise gives him a strong perspective on how net lease assets are sourced, evaluated, and selected.
The NNNBuyside team is comprised of Net Lease experts in transactions, marketing, and technology.

About NNNBuyside
NNNBuyside is a dedicated net lease acquisition advisory firm focused exclusively on representing buyers of single-tenant NNN assets across the United States.

How We Deliver Reliable Passive Income
We Sit At Your Side Of The table
The firm does not take listings. It does not operate under dual agency. It does not align with seller representation.
Every engagement is structured around protecting buyer capital, negotiating favorable terms, and identifying assets that meet clearly defined investment criteria.
This structure removes misaligned incentives and creates a disciplined acquisition process built around long-term performance rather than transaction velocity.
Asset Evaluation Strategy
NNNBuyside evaluates each opportunity through structured review of:
- Tenant credit and guarantor strength
- Lease structure and rent escalations
- Location durability and demand drivers
- Replacement cost and residual value
- Market cap rate context and liquidity
The objective is capital preservation first, yield second.
A Structured Acquisition Process
Clients are advised through a defined acquisition framework:
- Investment thesis development
- Market and tenant targeting
- On-market and off-market sourcing
- Financial and lease underwriting
- Negotiation strategy
- Due diligence coordination
- Debt coordination when required
- Closing execution
This approach reduces friction and improves clarity throughout the transaction cycle.
Depth Across Tenant Categories
NNNBuyside has executed transactions across key net lease categories, including:
- Quick service restaurants
- Pharmacies
- Gas and convenience
- Child care
- Dollar stores
- Fitness
- Banks
- Medical
Each category is evaluated through tenant performance, store economics, and guarantor analysis rather than surface-level cap rate comparisons.
Designed for Long-Term Capital
NNNBuyside primarily serves experienced private investors who seek:
- Assets in specific markets or locations
- Geographic and tenant diversification
- Durable passive income
- Credit-backed tenancy
- Structured rent growth
- Reduced operational burden
The firm favors long-term hold strategies and disciplined portfolio construction over speculative yield chasing.
Data-Driven Precision
Through alignment with Net-Trade’s niche net lease infrastructure, NNNBuyside leverages advanced filtering, detailed tenant profiles, and structured listing analysis to identify best-fit assets with greater speed and precision.
This combination of brokerage experience, platform development expertise, and disciplined underwriting provides clients with an advisory advantage not typically available in traditional transactional brokerage environments.
