Labs @Greenfield

The Labs@Greenfield initiative operates primarily through our subsidiary AVM Analytics.  In the Labs, we focus on building complex valuation tools and algorithms for the real estate and build environment-related industries. Leveraging decades of experiences in real estate appraisal, mass valuation and urban analytics, we focus on providing bespoke algorithms, processes, analyses and data visualization for clients in need of tailored solutions that off-the-shelf software or generic consulting firms cannot supply.

Direct Support

Based in Seattle, we work as direct consultants, contractors, and/or in partnership arrangements, depending on the project.


We leverage decades of experience in real estate appraisal, mass valuation and urban analytics to focus on providing tailored algorithms, processes, analyses and data visualization for clients in need of tailored solutions that off-the-shelf software or standard valuation firms cannot supply.

Bespoke Tools

AVM Analytics combines a team of data scientists and statisticians with a collection of industry experts (appraisers and economists) in order to build custom market analysis tools for the real estate and built environment industries.

Data Curation

From Data Entry to Database Development, let our team help you turn your raw real estate data into useful information.

AVM Analytics


Reproducibility and transparency are the core tenets of our product design and workflow strategy. We value honesty in algorithms and are working hard to shatter the ‘black box’ image often associated with mass valuation and other data science tools used in the urban analytics domain. To help accomplish this, AVM Analytics provides direct customer support for our products so any questions can be answered directly by the data scientist or analyst who developed or maintains our tools, products or analyses.

Additionally, as we have benefited greatly from open source software and data we are aiming to release a number of our tools, algorithms and datasets into the public domain in the near future. Watch our blog for more information about our work in this arena: LABS@Greenfield


AVM Analytics has partnered with Attom Data Solutions  to create a nation-wide Automated Valuation Model (AVM). Our modeling approach here focused on transparency and user support, while maintaining overall hit rates and accuracy figure comparable to other commercially available products.

Retrospective, Legal Grade AVMs

We have an extensive background in developing retrospective automated valuation models for use in legal matters, from eminent domain to class action litigation. AVM Analytics supports a number of Greenfield Advisors’ larger legal projects. All of our processes and models are meticulously document and reproducible by all parties in evidentiary discovery situations.

Custom AVM Products

Our AVM software has been designed to be flexible with regard to data source, property type and modeling approach. If you have a property valuation need, regardless of the size or scope, there is a high likelihood that we can fit your needs into a structured, standardized, and transparent mass valuation framework.

Rental Market Models

AVM Analytics is currently gathering a wide variety of rental data, both historical and current, to support the development of advanced rental market models. If you need deeper insights into residential rental markets, traditional and short-term (Airbnb, etc.), we can help.

Bespoke Tools

We believe that by combining technical know-how with real world experience, we can build the best tools for extracting valuable information from large datasets.  At AVM Analytics knowing what data to analyze and why is just as important as the code and software that underlying our tools.

House Price Indexes

Leveraging recent internal research, AVM Analytics is building a custom area house price index product. Need market trends for an area that isn’t traditionally covered (Metro Region, ZIP Code, County, etc.), let us know and we can produce custom indexes for any market area or submarket type (3-bedroom homes only, for example).

Mortgage Leads Categorization

AVM Analytics is currently partnering with a leading mortgage lead supplier to provide improved rankings of mortgage lead conversion rates. This product is currently under development. Please check our blog for information on the release of this product.

Rent-Price Ratio Analysis

Understanding the relationship between rents and prices is fundamental to long-term success in residential real estate investing and analysis. AVM Analytics has pioneered a new approach to ‘de-bias’ traditional rent-price ratio estimates and provide a clearer analysis of market mechanics. Technical details are available.

Short Term Rental (AirBnB) Potential

From the analyst’s perspective, short term rental market (Airbnb and its competitors) are big on hype but short on hard data and analyses. AVM Analytics is looking to change that. We are developing a number of models aimed at informing: 1) the impact of short term rental potential on home values; and 2) the decision between leasing long-term or short-term.

AVM Analytics has a well-trained data entry team whose focus is on providing efficient, detailed and documented data entry regardless of the variety of data sources.

Data Integration

Successfully building operable real estate valuation and market analysis databases is usually an exercise in integrating data of many difference scopes and sizes from many different sources. Let AVM Analytics’ decades of experiences help bring your data together.
