Home Equity Sharing Calculator
Home equity sharing products (HEI) give cash today for a slice of future appreciation. This calculator compares the total cost against a traditional HELOC so you know which structure is cheaper for your specific market.

How the math works
HEI products (Unison, Point, Hometap, HomeTap, Unlock) give a homeowner a lump sum in exchange for 15-50% of future appreciation. No monthly payments. Compared to a HELOC, HEI is cheaper in flat-to-moderate markets and more expensive when appreciation runs hot.
HEIs work best when the homeowner can't qualify for a HELOC (low income, DTI-constrained), is cash-flow sensitive, and expects moderate appreciation. They work worst in hot markets where the investor captures large appreciation upside.

How this calculator works
What this page estimates
This Home Equity Sharing Calculator is built to give a quick, browser-based estimate for home equity sharing. Home equity sharing products (HEI) give cash today for a slice of future appreciation. This calculator compares the total cost against a traditional HELOC so you know which structure is cheaper for your specific market. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the home equity sharing result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this home equity sharing estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions
When does HEI beat HELOC?
Low-appreciation markets and short holds. If appreciation runs 2-3%, HEI is often cheaper than HELOC servicing over 10 years. In 6%+ appreciation markets, HELOC wins easily.
Are HEI payments tax-deductible?
No — HEI payback at exit is treated as a sale of an equity interest, not interest expense. No ongoing tax deduction. Compare after-tax HELOC interest (if deductible for acquisition use) against the HEI.
Can I have both?
Typically no — most HEI products require first-lien position behind the primary mortgage. Usually can't have HEI and HELOC simultaneously unless HEI contract permits. Read the fine print.
