3Y Estimate

3Y's calculated goal-supported price for a specific property and goal — the goal-convergent price applied to that property.

A market estimate asks "what might others pay?" The 3Y Estimate asks "what price does your selected goal support?" It gives investors a disciplined target for underwriting, negotiation, and due diligence.

3Y Location Score

3Y's 0–100 location signal reflecting housing, rental, economic, urban, climate, and safety conditions around a property.

Separate from the 3Y Estimate™. The Location Score describes surrounding market support and location risk; the 3Y Estimate calculates the goal-convergent price supported by the deal's financial profile and the investor's selected goal.

A

ACS — American Community Survey

The Census Bureau's rolling demographic and economic survey, and the primary data source behind 3Y's tract-level analytics.

Read more →

B

BLS — Bureau of Labor Statistics

The federal source for wages, employment, and inflation data behind 3Y's local labor signals.

Read more →

C

Capital

The total cash you put into a deal at acquisition — down payment, closing costs, and make-ready combined.

Read more →

Capitalization rate (cap rate)

The annual unlevered yield a property produces based on its net operating income and price.

Read more →

Cash on cash return

Annual pre-tax cashflow as a percentage of total cash invested — the leverage-aware return on the dollars you actually put down.

Read more →

Cash velocity

Monthly net cashflow per unit using the 3Y Estimate™ — one of the three selectable investor goals.

Read more →

Census tract

A subdivision of a county, typically 1,200–8,000 people, designed to be relatively homogeneous in population and economic conditions.

The standard geographic unit for ACS data and for 3Y location scoring. Tracts are statistical constructs, not administrative or community boundaries, and are kept stable across decennial Census cycles to support comparison over time.

Read more →

Closing costs

One-time fees paid at acquisition — title, escrow, recording, lender, transfer taxes, prorations.

Typically 2–5% of price. Often underestimated by new investors and rolled into total investment when computing yield.

Read more →

D

DSCR — Debt Service Coverage Ratio

Net operating income divided by annual debt service — a measure of how comfortably property income covers loan payments.

Read more →

E

Exit strategy

A possible future path for an investment property, such as holding, refinancing, or selling.

Projections become more useful when they help an investor think about what the property may make possible next — without guaranteeing future value, financing, or sale proceeds.

Read more →

F

FEMA flood zone

Federal hazard designations for flood risk and how 3Y surfaces them in property reports.

Read more →

FHFA HPI — House Price Index

The Federal Housing Finance Agency's repeat-sale price index, the source for 3Y's metro and state appreciation signals.

Read more →

G

Goal-convergent price

The price supported by a stated investment goal — yield, cash flow, or DSCR target — under the current assumptions.

A reverse valuation lens beside market estimates. Most tools work forward: input price, output yield. 3Y works in reverse: input goal, output the price the modeled assumptions support. When applied to a specific property, the goal-convergent price is reported as the 3Y Estimate.

Read more →

GRM — Gross Rent Multiplier

Price divided by annual gross rent — a fast pre-expense screening ratio.

Read more →

H

Home price growth

A recency-adjusted annual property value growth assumption based on recent and longer-term tract-level FHFA price trends.

Read more →

L

Local area

An adaptive local geography around the property's census tract, generally targeting 12,000 residents within a five-mile walk.

Used to resolve local context for 3Y Location Score™ without requiring a fixed number of census tracts or pretending a fixed radius means the same thing everywhere.

Read more →

M

Make-ready

Upfront cost to prepare a property or units for occupancy — distinct from value-add renovation.

Read more →

Market estimate

An estimated price based on outside market evidence, such as comparable sales or an applied market cap rate.

Market estimates describe external pricing context. Goal-convergent valuation solves for the price an investor's goal can support.

Read more →

Median household income

ACS-published midpoint of household incomes in a geography — the foundation for affordability math.

Read more →

N

Neighborhood

Concentric 1-, 3-, and 5-mile rings around the property.

Used in 3Y reports to show how population, households, and rental demand change with distance from the property. Distinct from Local Area, which is a single adaptive radius rather than fixed rings.

Read more →

NOI — Net Operating Income

Net Operating Income. Gross rent minus operating expenses, before debt service.

The baseline of property economics. Cap rate, DSCR, and most yield metrics start here.

Read more →

O

Operating cap rate

Modeled net operating income divided by the purchase price used in the analysis.

A property-level income-yield measure before financing. Useful for understanding operating performance, but not a complete investment decision.

Read more →

OpEx ratio

Operating expenses as a share of gross income — what proportion of rental income gets eaten by costs.

Read more →

P

Population growth

Five-year change in population for a geography, sourced from ACS — the demand-side input behind long-horizon projections.

Read more →

Poverty rate

Share of residents below the federal poverty line — used in 3Y location scoring as a structural risk indicator.

Read more →

Principal paydown

The reduction in remaining loan principal as scheduled mortgage payments repay debt over time.

Principal paydown can build an owner's capital position, but it is not spendable cash unless accessed through a refinance or sale.

Read more →

R

Rent growth

A recency-adjusted local rent-growth assumption blending 3-year and 8-year HUD Small Area Fair Market Rent trends.

Read more →

Rent-to-income ratio

Share of typical income spent on rent — a measure of affordability and rent-growth headroom.

Read more →

Replacement cost

The estimated cost to rebuild a structure today — used by insurance and as a sanity floor on price.

Read more →

S

Stock market comparison

A simplified broad-market buy-and-hold benchmark used to give 3Y return projections familiar context.

In 3Y reports, the stock market comparison is not a guarantee, investment recommendation, or prediction of future market performance. It is a plain-language benchmark based on the common long-term investing idea that broad U.S. equity returns have historically been near the high single digits to low double digits, which can roughly double money over an 8–10 year window.

Read more →

T

The 1% rule

Monthly effective rent as a share of asking price — a quick screen at the price in front of the investor.

Read more →

Total investment

Purchase price plus closing costs plus make-ready.

The number that should drive yield calculations, not price alone.

Read more →

V

Vacancy

Expected share of rent lost to vacancy — an operational input distinct from the Census vacant ratio.

Read more →

Vacant ratio

Census-published share of housing units classified vacant.

Includes seasonal, transitional, and long-term vacant — a different measure than rental vacancy. High vacant ratios in non-resort markets often signal demand weakness.

Read more →

W

Wind-pool county

Coastal counties where standard property insurance excludes wind damage, requiring separate coverage through state pools or specialty carriers.

Read more →

Z

ZIP code

A USPS delivery boundary — useful for mail, weak for analytics.
