Real Estate & Finance Glossary
Plain-language definitions of the terms that come up most often in David Denenberg’s writing on Long Island housing, personal finance, and emerging markets.
Real estate and personal finance each have their own vocabulary, and much of it is designed to sound more technical than it needs to. The result is that ordinary people walk away from important decisions feeling like they missed something, even when the underlying idea was simple.
This glossary collects the terms that come up most often in David Denenberg’s writing on Long Island housing, personal finance, and emerging markets, and defines each one in plain language. The goal is not to be exhaustive; it is to be useful. A definition here should be enough to read an article, evaluate an offer, or follow a conversation without stopping to look things up elsewhere.
Where a term has a precise legal or technical meaning, that meaning is preserved; where the common usage is looser, the glossary says so. Real estate terms and finance terms overlap more than people expect. Equity, leverage, and appreciation show up in both conversations, and understanding them once makes both clearer. The same is increasingly true of digital assets, where older ideas about ownership and liquidity are being applied to new structures.
New terms are added as the market evolves and as questions from readers make clear which ones need explaining. If a term you are looking for is not here, that is a useful signal: send it through the contact page, and it may be added to a future update.
Real Estate
- Appreciation
- Appreciation is the increase in a property's value over time. On Long Island, appreciation is driven by limited supply, location, and condition; it is never guaranteed and rarely linear.
- Months of Supply
- Months of supply estimates how long it would take to sell every currently listed home at the current sales pace. Below roughly six months is generally considered a seller's market; above it tilts toward buyers.
Finance & Investing
- Equity
- In personal finance, equity is the portion of an asset you truly own after any debts against it are paid. In a home, it is the market value minus the mortgage balance. Building equity is how most households accumulate wealth over time.
- Leverage
- Leverage is using borrowed money to increase your exposure to an asset. A mortgage is the most common form of leverage for households. It magnifies both gains and losses, which is why the size of the loan matters as much as the price of the home.
Digital Assets
- Stablecoin
- A stablecoin is a cryptocurrency designed to hold a steady value, usually by being backed by reserves of dollars or other assets. It is used as a bridge between traditional money and digital markets, though the quality of the backing varies.
- Tokenization
- Tokenization is the representation of a real asset, like real estate, as digital tokens on a blockchain, allowing fractional ownership. It promises easier access and liquidity but does not remove the underlying risks of the asset itself.
