Definitions and reference terms for understanding how property actually works
Property decisions involve more than listing facts.
A buyer, seller, or owner may need to understand physical conditions, legal rights, infrastructure, ownership structure, regulation, market behavior, transaction timing, seasonality, and long-term responsibilities—and then determine what those facts actually mean together.
This glossary provides concise definitions for terms used throughout Sander Scott’s property guidance and the broader Property Decision Intelligence knowledge system.
Important classification note: Inclusion in this glossary does not mean that every term is a Property Decision Intelligence framework.
This page includes admitted PDI frameworks, applied PDI teaching terms, ordinary real estate concepts, legal and regulatory terms, property-condition analyses, guides, and educational resources.
Where a term has a dedicated canonical page, that page controls the fuller public explanation.
Property Decision Intelligence
Property Decision Intelligence™
Property Decision Intelligence is the discipline of strengthening how people observe property, interpret what those observations mean, and exercise responsible judgment in consequential property decisions.
Property Decision Intelligence™ was founded by Sander Scott. His present public educational and professional implementation is principally directed toward individuals and households making consequential property decisions.

Core Property Decision Intelligence Frameworks and Concepts
Property Usability
Property Usability is the practical and sustainable function a property can support under the real conditions governing its use and ownership.
It is a property-side analysis. Whether those supported functions fit a particular person or purpose is a later judgment.
Read the Property Usability framework →
Ownership Patterns
Ownership Patterns examines how rights, responsibilities, use, control, burdens, benefits, relationships, and change interact across an ownership arrangement over time.
Interpretation Gap Risk
Interpretation Gap Risk arises when the meaning assigned to a fact, rule, document, statement, or condition is not adequately supported by how it actually operates.
Read Interpretation Gap Risk →
Execution Gap Risk
Execution Gap Risk examines the gap between an action that must occur and the real ability to complete that action under the people, systems, resources, authority, and time available.
Control Gap
Control Gap examines the difference between an outcome someone depends on and the actual control available to make that outcome occur.
Buyer Friction Signal
Buyer Friction Signal is a recurring pattern of buyer hesitation, confusion, concern, delay, or objection that may reveal something meaningful about how the market is interpreting a property.
Repeated buyer reaction is evidence to interpret, not automatic proof that the buyers are correct.
Timing Friction
Timing Friction arises when the timing required by a property decision does not align with the timing available to the people, transaction, financing, sale, approval, or other dependency involved.
Cost Conversion Risk
Cost Conversion Risk is the risk that reducing or eliminating one ownership cost replaces it with another cost that may be more fixed, less controllable, less visible, or more difficult to avoid.
A common application is downsizing: a smaller home does not automatically mean lower total ownership cost.

Transaction and Decision Terms
Transaction Friction
Transaction Friction is the drag created when unresolved information, interpretation, documentation, approvals, costs, responsibilities, timing, or control make a real estate transaction harder to evaluate or complete.
Transaction Friction is used on this site as an applied transaction concept, not as a separate admitted PDI framework.

Post-Closing Occupancy
Post-Closing Occupancy is a transaction arrangement in which the seller remains in possession of the property for an agreed period after legal ownership transfers.
The rights, obligations, risk allocation, insurance, possession terms, and remedies depend on the actual agreement and applicable law.
Right of First Refusal
A Right of First Refusal may require an owner to give another person or entity an opportunity to purchase or match specified transaction terms before a sale can proceed.
The actual effect depends on the controlling recorded document, agreement, and applicable law.
Easement
An easement is a legal right affecting another person’s use of land or providing a right to use land for a specified purpose.
For property decisions, an easement may materially affect access, privacy, maintenance, improvements, buildability, waterfront use, control, and Property Usability.
The actual legal rights must be determined from the recorded documents and qualified legal or title review.
Land and Buildability Terms
Northern Michigan Land Guide
The Northern Michigan Land Guide is the site’s applied guide for evaluating vacant land through access, buildability, septic, infrastructure, zoning, physical conditions, ownership, and long-term use.
Buildability Gap
Buildability Gap examines the difference between what a parcel appears capable of supporting and what can actually be supported after the governing physical, legal, regulatory, access, infrastructure, and site conditions are understood.
Infrastructure Gap
Infrastructure Gap examines the difference between an intended property function and the infrastructure available to support it.
Infrastructure may include access, electrical service, well, septic, internet, drainage, grading, clearing, and other systems required to make the property function.
Septic Suitability
Septic Suitability examines whether site conditions appear capable of supporting an appropriate on-site wastewater system and what limitations or requirements govern that capability.
Actual septic approval belongs to the applicable health authority and qualified professionals.
Legal Access
Legal Access concerns the legally recognized right to reach property.
Legal access should be distinguished from practical access. A recorded right may exist while the physical route remains difficult, seasonal, undeveloped, or otherwise limited.
Parcel Size vs. Buildable Area
Parcel Size vs. Buildable Area is the distinction between the total acreage or square footage of land and the portion that can realistically support the intended development or function.
Wetlands, setbacks, slopes, septic, access, zoning, drainage, utilities, and other constraints can make these figures very different.
Land Division
Land division is the legal process by which parcels may be divided or reconfigured under applicable law and local requirements.
The ability to divide a specific parcel should be verified from current governing law, parent-parcel history, the local reviewing authority, access standards, zoning, and appropriate professional documentation.
Drainage District
A drainage district is a legally established area associated with a public drainage system or drainage obligations.
The rights, assessments, responsibilities, and procedures depend on the applicable governmental records and law.
Vacant Land Due Diligence
Vacant Land Due Diligence is the process of investigating whether land can actually support the contemplated function before relying on acreage, appearance, listing descriptions, or assumptions.
Typical issues may include access, zoning, septic, utilities, wetlands, slopes, drainage, buildable area, infrastructure, restrictions, and development cost.
Vacant Land Usability
Vacant Land Usability is an application of Property Usability to vacant land.
It asks what practical and sustainable functions the parcel can support under the physical, legal, infrastructure, regulatory, environmental, and ownership conditions governing it.
Waterfront Property Terms
Northern Michigan Waterfront Property Guide
The Northern Michigan Waterfront Property Guide is the site’s applied guide to waterfront ownership, rights, physical conditions, access, shoreline behavior, usability, and long-term ownership considerations.
Waterfront Usability
Waterfront Usability examines the practical water-related functions a waterfront property can support under the physical, legal, access, environmental, ownership, and seasonal conditions governing it.
Waterfront Ownership
Waterfront Ownership describes the combination of legal rights, access, control, responsibilities, physical shoreline conditions, shared rights, public rights, and other conditions attached to owning or using property connected to water.
Waterfront Views vs. Waterfront Use
Waterfront Views vs. Waterfront Use distinguishes the visual benefit of seeing water from the practical ability to reach, use, swim, boat, dock, walk, or otherwise interact with it.
A view is not the same thing as access or usability.
Waterfront Due Diligence
Waterfront Due Diligence is the investigation required to understand how waterfront rights, shoreline conditions, access, water depth, exposure, dockability, restrictions, infrastructure, and other property-specific conditions affect practical use.
Direct Private Frontage
Direct Private Frontage generally describes waterfront where the individual parcel itself directly adjoins the water.
The actual rights associated with frontage depend on title, applicable law, public rights, recorded restrictions, and physical conditions.
Shared Waterfront Access
Shared Waterfront Access describes water access provided through an association, easement, common area, subdivision arrangement, park, road, or other shared structure rather than direct private frontage owned solely as part of the parcel.
Direct Waterfront vs. Shared Waterfront Access
Direct Waterfront vs. Shared Waterfront Access is a comparison between direct frontage and shared-access arrangements in terms of rights, privacy, control, responsibility, convenience, rules, cost, and Property Usability.
It is not automatically a separate PDI framework.
Deeded Access vs. Public Access
Deeded Access vs. Public Access is a rights-and-access distinction.
Deeded access depends on private recorded rights.
Public access depends on rights available to the public through applicable governmental or public-trust authority.
Neither term alone establishes what activities are permitted.
Public Access
Public Access is access legally available to members of the public.
Its scope depends on the specific property, public right, governmental authority, and applicable law.
Public Road End
A public road end is the end of a public road or right-of-way at or near a body of water.
What the public may lawfully do there depends on the specific road dedication, public rights, court decisions, and applicable law.
Dockable Shoreline
Dockable Shoreline is an analysis of whether the shoreline can practically and lawfully support a dock or similar water-access structure.
It may depend on water depth, bottom conditions, exposure, rights, regulations, seasonal conditions, and other physical or legal constraints.
Frontage Trap
Frontage Trap describes the mistake of assuming that the number of waterfront feet alone tells a buyer how useful, private, accessible, or valuable the waterfront will be.
Frontage is an observation.
Usability requires interpretation.
Big Water
Big Water is an applied descriptive term for broad, exposed water settings where wave energy, wind, shoreline behavior, views, boating conditions, and maintenance may differ from more protected water.
Protected Water
Protected Water describes water settings sheltered from some open-water exposure by geography or location.
Protection can affect wave conditions, docking, swimming, shoreline stability, and day-to-day water use.
Big Water vs. Protected Water
Big Water vs. Protected Water is a waterfront comparison that helps explain how dramatic open-water settings and more protected water settings may support different ownership and use patterns.
It is not automatically a separate PDI framework.
Great Lakes Waterfront
Great Lakes Waterfront refers to property adjoining the Great Lakes.
Rights and responsibilities may involve state law, public-trust principles, shoreline regulation, water levels, erosion, and other conditions that differ from some inland-water settings.
Inland Lake Waterfront
Inland Lake Waterfront refers to property adjoining an inland lake.
Rights and practical use may depend on riparian law, access, water depth, shoreline conditions, lake characteristics, restrictions, and public use.
Bottomlands
Bottomlands are lands beneath a body of water.
Ownership and rights involving bottomlands can be legally significant for docking, mooring, shoreline activity, and waterfront use.
Property-specific conclusions require qualified legal and title review.
Ordinary High Water Mark
The ordinary high water mark is a legal and physical concept used in waterfront regulation and public-rights analysis.
Its exact definition and application depend on the governing law and water body.
Do not rely on a glossary description to establish a property-specific boundary.
Public Trust Doctrine
The Public Trust Doctrine is a body of law concerning public rights in certain waters and related resources.
Its application is jurisdiction-specific and should be verified from controlling Michigan law and qualified legal sources.
Riparian Rights
Riparian rights generally concern rights associated with land bordering inland lakes, rivers, or streams.
The exact rights depend on Michigan law, title, boundaries, public rights, and property-specific circumstances.
Littoral Rights
Littoral rights generally concern rights associated with land adjoining large bodies of water.
Terminology and legal treatment can vary, so property-specific conclusions should be verified through controlling Michigan law and qualified counsel.
Shoreline Setbacks
Shoreline setbacks are required distances that may limit where structures, septic systems, improvements, or other activity can occur near water or related environmental features.
The controlling setback depends on the applicable jurisdiction, ordinance, agency, and property conditions.
Waterfront Supply Constraints
Waterfront Supply Constraints describes structural conditions that limit the creation or replacement of true waterfront inventory.
Examples may include geography, existing development, conservation, regulation, physical shoreline conditions, and limited developable frontage.
Property Experience and Ownership Terms
Access Friction
Access Friction describes physical, logistical, seasonal, legal, or operational conditions that make reaching or using a property more difficult than its basic description suggests.
Practical Privacy
Practical Privacy describes how private a property actually feels and functions after access patterns, neighboring activity, topography, vegetation, public areas, trails, roads, and nearby uses are considered.
Seasonal Honesty
Seasonal Honesty evaluates property conditions across the full year rather than judging the property only during its most favorable season.
Use Decay
Use Decay is an applied observation describing how a property feature or amenity may be used less frequently over time than originally expected.
It is useful as a question about ownership behavior; it is not a prediction that use will necessarily decline.
Northport Golf Cart-ability
Northport Golf Cart-ability is a local applied term describing how practically a property connects to village destinations by lawful golf-cart travel.
Actual lawful routes and vehicle requirements should be checked against current local rules.
Long-Term Property Fit
Long-Term Property Fit describes the later person-and-purpose judgment about whether a property’s capabilities, burdens, responsibilities, costs, adaptability, and ownership pattern continue to work for a particular household over time.
It should not be confused with Property Usability, which is property-side capability analysis.
Short-Term Rental and Regulatory Terms
STR Viability
STR Viability examines whether a property can realistically function as a short-term rental after regulatory, physical, operational, financial, management, ownership, market, and time conditions are considered together.
Jurisdiction
For STR evaluation, jurisdiction means identifying which governmental and private authorities actually control the proposed rental use.
These may include municipalities, zoning authorities, health departments, associations, condominium documents, deed restrictions, or other governing sources.
The term should not be interpreted as creating a separate legal doctrine.
STR Evaluation Stack
STR Evaluation Stack is an applied teaching structure for evaluating rental feasibility in layers rather than beginning with projected income alone.
Typical layers may include regulation, property capability, operations, management, financial assumptions, documentation, and time risk.
Regulatory Friction
Regulatory Friction describes the difficulty, delay, cost, or uncertainty created when a property decision depends on multiple rules, permits, agencies, approvals, or procedures.
Regulatory Fragility
Regulatory Fragility describes dependence on regulatory conditions that may be vulnerable to change.
A current permission may be valuable without being permanent.
The degree of fragility must be evaluated from the actual governing authority and rules.
STR-Friendly vs. STR-Viable
STR-Friendly vs. STR-Viable distinguishes a generally favorable rental environment from a specific property’s actual ability to function successfully and sustainably as a short-term rental.
Location alone does not establish viability.
Tax, Assessment, and Ownership-Cost Terms
Tax Reality Shift
Tax Reality Shift is an applied term describing the difference between a current owner’s property-tax situation and the tax situation a future owner may face after transfer, reassessment, exemption changes, classification changes, or other events.
Taxable Value Uncapping
Taxable Value Uncapping is a Michigan property-tax concept affecting taxable value after certain transfers of ownership.
The exact consequences should be verified with the applicable assessor, Michigan law, and a qualified tax professional before relying on an estimate.
Special Assessment
A special assessment is a charge imposed on affected property to fund specified public improvements or services.
Responsibility, amount, timing, and allocation depend on the actual governmental assessment record.
Assessment Exposure
Assessment Exposure is an applied property-decision term describing the possibility that current or future infrastructure or improvement obligations may become a meaningful ownership cost.
Market and Buyer-Behavior Terms
Northern Michigan Market Signals
The Northern Michigan Market Signals guide interprets recurring buyer and seller behavior, pricing response, uncertainty, scarcity, usability, and other market evidence.
Pricing vs. Positioning
Pricing vs. Positioning distinguishes a problem caused primarily by asking price from one caused by how clearly the property’s condition, use, rights, benefits, limitations, or appropriate buyer are being communicated.
Both may exist at the same time.
Buyer Hesitation as Market Information
Repeated independent buyer hesitation can sometimes provide useful evidence about how the market is interpreting a property.
It does not prove that every objection is correct.
Repeated patterns deserve interpretation.
See Buyer Friction Signal and Northern Michigan Market Signals.
