Mortgage:
A legal agreement in which a borrower uses real property as collateral for a loan. Mortgages can be fixed-rate or adjustable-rate (ARM), depending on whether the interest remains constant or varies with an index. Adjustable-Rate Mortgage (ARM): A home loan with an interest rate that changes periodically, usually based on a benchmark index such as the Euribor or U.S. Treasury rate. It starts lower than a fixed-rate loan but carries interest-rate risk. Conventional Loan: A mortgage is not insured or guaranteed by the government. Typically offered by private lenders, these loans are based on creditworthiness and the size of the down payment. |

Down Payment:
The portion of the property purchase price that the buyer pays upfront. A higher down payment lowers monthly payments and risk to lenders.
Refinancing:
Replacing an existing mortgage with a new one, usually to secure a lower rate or change the loan term. Common when market rates fall.
Debt & Equity:
Debt is borrowed money that must be repaid with interest; equity is the investor’s own capital. Successful real estate financing balances both — too much debt increases risk, too little limits returns.
Leverage:
Using borrowed capital to control a larger asset and magnify potential returns. Leverage works both ways — it can increase gains in up markets but amplify losses when values fall.
Cash Flow:
The money remaining after operating expenses and loan payments is deducted from gross rental income. Positive cash flow signals a healthy investment; negative cash flow means ongoing losses.
Compound Interest:
Interest calculated on both the initial principal and accumulated past interest — the “interest on interest” effect that grows investments over time.

II. Housing Market Dynamics & Economic Cycles

(How real estate markets move through expansion and contraction.)
|
Expansion Phase:
Characterized by economic growth, rising employment, strong demand, and increasing construction. Property values rise as buyers compete for a limited supply. Peak: When supply begins to outpace demand, prices stabilize. Developers may still be building, but the market is close to saturation. Contraction: Sales and construction are slow as demand weakens. Prices begin to fall, and liquidity decreases — properties take longer to sell. |

Trough:
The bottom of the cycle. Prices stabilize after a decline, inventory clears, and the market begins to recover. Often the best time for investors to buy undervalued assets.
Real Estate Cycle:
A recurring pattern of expansion, peak, contraction, and recovery. Understanding the cycle helps investors identify when to buy, hold, or sell.
Demand and Supply:
Demand represents the buyers’ willingness and ability to purchase; supply is the amount of property available for sale. Prices rise when demand exceeds supply and fall when supply surpasses demand.

Economics:
The study of how societies allocate limited resources among competing uses. Real estate lies at the intersection of economics, finance, and social policy. Macroeconomics vs. Microeconomics: Macroeconomics studies large-scale economic activity (GDP, inflation, unemployment), while microeconomics focuses on individual markets and consumer decisions. Gross Domestic Product (GDP): The total market value of all goods and services produced within a country. A key measure of national economic health. Inflation: A sustained increase in overall price levels. Moderate inflation can stimulate investment, but excessive inflation erodes purchasing power and raises interest rates. Deflation: A fall in general price levels — often accompanied by recessions, falling wages, and reduced investment. |

Stagflation:
A rare combination of slow growth, high unemployment, and rising prices. It is difficult for policymakers to fix because traditional tools often worsen one problem while solving another.
Fiscal Policy:
Government decisions on taxation and spending. Fiscal stimulus can support housing demand, while austerity tends to suppress it.
Monetary Policy:
Actions by a central bank to influence money supply and interest rates.
A form of monetary stimulus where central banks buy government bonds to inject liquidity and lower long-term interest rates — often boosting property investment indirectly.
Money Supply:
The total amount of currency and bank deposits circulating in an economy. Too much money chasing too few goods fuels inflation.

Monetary Policy:

- In the U.S., this is managed by the Federal Reserve (the Fed).
- In Europe, by the European Central Bank (ECB).
Lower rates encourage borrowing and investment; higher rates cool inflation but can slow real estate.

IV. Property Valuation, Metrics & Returns

Value:
The monetary worth of a property as perceived by buyers and sellers. Determined by Demand, Utility, Scarcity, and Transferability — known as the D.U.S.T. principle. Net Operating Income (NOI): Gross rental income minus operating expenses (excluding financing costs). The foundation for calculating cap rates and property value. Capitalization Rate (Cap Rate): NOI divided by the property’s purchase price. A lower cap rate typically signals a higher value or lower risk; conversely, a higher cap rate indicates a higher risk or greater return potential. Return on Investment (ROI): The percentage gain or loss on an investment relative to its cost. ROI = (Net Profit / Total Investment) × 100. |

Internal Rate of Return (IRR):
The discount rate that makes the net present value (NPV) of cash flows equal to zero. A measure of an investment’s overall profitability over time.
Appreciation:
The increase in property value over time due to market trends, improvements, or inflation.
Depreciation:
The decrease in property value due to wear, age, or obsolescence. In finance, it also serves as a tax deduction for income-producing property.
Liquidity:
The ease with which an asset can be converted into cash without significant loss. Real estate is generally less liquid than stocks or bonds.
Risk and Diversification:
Spreading investments across asset classes or markets reduces exposure to localized downturns.

Lender:
A financial institution or individual that provides capital for property purchases. Can include banks, credit unions, mortgage companies, or private investors. Mortgage Broker: An intermediary who arranges financing between borrower and lender, often accessing multiple loan programs. REIT (Real Estate Investment Trust): A company that owns or finances income-producing real estate. REITs enable small investors to access large property portfolios, much like mutual funds. Federal Housing Administration (FHA): A U.S. government agency that insures mortgages for borrowers with lower credit or down payments. |

Bond:
A fixed-income instrument representing a loan made by an investor to a borrower. Bonds fund projects and influence mortgage rates through yield movements.
Private Mortgage Insurance (PMI):
Insurance required by lenders when a borrower’s down payment is less than 20%. Protects the lender in case of default.
Pension Fund:
A pooled investment vehicle that provides retirement income. Pension funds are major institutional investors in real estate.
Finance Company:
Private firms offering consumer loans, including home equity financing.

Property Tax:
A recurring tax based on the assessed value of property, funding local services such as schools, roads, and safety. Fiscal Stimulus: Government actions (tax cuts or spending increases) designed to boost economic growth and demand — often raising short-term property activity. Urban Policy & Zoning: Regulations governing the use of land. Zoning affects supply, density, and property value. Sustainability and Green Building: Policies and practices promoting energy efficiency, renewable materials, and environmental design. Increasingly tied to tax incentives and higher long-term value. Cross-Border Investment: The purchase of property by foreign investors. Exchange rates, tax treaties, and monetary policy all influence these flows. |

Exchange Rate (EUR/USD):
The value of one currency relative to another. A strong dollar makes European real estate cheaper for American buyers.
Housing Affordability:
The relationship between household income and housing costs. Influenced by wages, interest rates, and fiscal policy.
Financial Stability:
A state where financial systems and real estate markets operate without excessive volatility or systemic risk. Central banks monitor property prices to prevent imbalances.

By Piero Lorenzo — San José State University (ECON 100W, Fall 2025) Awarded 114/110.
This research paper examines how high inflation erodes U.S. housing affordability through three main channels: purchasing power, construction costs, and borrowing rates. It combines economic theory with empirical data from the Bureau of Labor Statistics, FRED, and the Urban Institute, offering insights relevant to policymakers and real estate professionals alike. |
