INVESTOR FUNDAMENTALS

Own 10% of a house. Ten percent of what?

The denominator matters as much as the percentage. A 10% label can describe several different economic claims.

U.S. educational guide · Original examples and analysis, with primary sources linked where used. Hypothetical figures are not offers, forecasts, or personalized financial or legal advice.

Write the claim as a sentence before calculating it

“Ten percent” is incomplete. It could mean ten percent of gross property value, ten percent of proceeds after debt and selling costs, ten percent of appreciation, or ten percent of an entity whose assets and liabilities must be understood. These are alternative hypothetical structures, not interchangeable names for the same investment.

Our first diligence test is to finish this sentence: I receive ___ percent of ___, after ___ is paid, at ___. If any blank requires a marketing representative to improvise, get the governing document and a worked settlement statement.

One house, three very different numbers

Imagine a home bought or valued initially at $1,000,000 and sold later for $1,100,000. Assume $66,000 in selling costs and a $600,000 mortgage payoff. The arithmetic leaves $434,000 before any additional claims. For this illustration only, assume the mortgage and selling costs are paid first. Actual priority requires the governing documents and a title review.

Hypothetical claimArithmeticAmount
10% of gross sale value10% × $1,100,000$110,000
10% of remaining equity10% × $434,000$43,400
10% of appreciation only10% × ($1,100,000 − $1,000,000)$10,000

Where did the original investment go?

Those three numbers are distributions under three isolated formulas. They are not comparable returns until the amount invested, any principal repayment, and every fee are specified. A $10,000 appreciation payment might sit on top of returned capital in one structure; in another structure, the quoted distribution already includes capital.

Ask for a line labeled return of contributed capital and a separate line labeled profit or loss. Then check whether the documents promise that distinction, or merely use it in an example.

A modest house-price decline can be a large equity decline

Now simplify: a $1,000,000 home has $600,000 debt, and we temporarily ignore costs. Starting equity is $400,000. A 10% fall in home value reduces it to $300,000, a 25% decline in equity. Debt amplifies the percentage change because the equity denominator is smaller.

This is original arithmetic, not a prediction. Mortgage amortization, additional liens, reserves, taxes, and sale costs would change the result. An investor buying an entity interest also needs to understand liabilities at the entity level.

Connect the formula to a legally identifiable claim

The SEC staff’s January 2026 tokenization statement explains that tokenized structures can confer different rights. A token balance alone therefore cannot answer the denominator question. Ask which document defines the economic claim and which record identifies its holder. The statement is staff analysis, not a property-title ruling or approval of an offering.

TAKE THIS TO THE CONVERSATION

Four questions worth asking.

  1. Is my percentage of value, equity, appreciation, or an entity?
  2. Does the advertised payout include my original capital?
  3. Which claims get paid ahead of mine?
  4. Who can add debt, issue more interests, or change the sale timetable?
