Unlike traditional loans, SAAs require no monthly payments—repayment occurs only when you sell, refinance, or reach a maturity date. According to the Urban Institute's 2023 report, SAAs have grown 340% since 2020, with $4.2 billion in originations in 2022 alone. These agreements are most suitable for homeowners needing cash for renovations, debt consolidation, or investment but who lack sufficient equity for a HELOC or cash-out refinance.

How Do Shared Appreciation Agreements Work?
A shared appreciation agreement (SAA) is a non-debt instrument. You receive a lump sum of cash—typically $50,000 to $200,000—from an investment company like Unison, Hometap, or Equify. In exchange, the investor receives a percentage of your home's future appreciation when you sell, refinance, or reach the end of the agreement term.
Example: You own a home worth $400,000, and you take $80,000 from an SAA provider. Five years later, you sell for $520,000—a $120,000 gain. If the agreement is for 35% of appreciation, you owe $42,000 (35% × $120,000) plus the original $80,000, totaling $122,000. You keep the remaining $78,000 in profit.
Key mechanics:
- No interest rate—the cost is purely appreciation-based
- No monthly payments—payment is deferred until a triggering event
- Trigger events: Sale, refinance, death, or maturity (typically 10–30 years)
- Appraisal required at both origination and termination
According to the Consumer Financial Protection Bureau (CFPB) 2022 advisory, SAAs are classified as "alternative financing products" and are not subject to TILA or RESPA in most states, though 12 states now have specific disclosure laws.
Actionable Step: Before contacting any provider, get a professional appraisal of your home's current value. Most SAA companies require this anyway, but having your own data helps negotiate terms.
What Are the Best Companies Offering Shared Appreciation Agreements?
Not all SAAs are created equal. Here's a comparison of the top five providers based on 2023–2024 SEC filings and consumer reviews.
| Company | Founded | Appreciation Share | Max Capital | Maturity | Fee Structure | BBB Rating |
|---|---|---|---|---|---|---|
| Unison | 2004 | 17.5–35% | $500,000 | 30 years | 3% origination fee | A+ |
| Hometap | 2017 | 20–35% | $300,000 | 10 years | 2.5% admin fee | A |
| Equify | 2019 | 25–40% | $250,000 | 10 years | 4% service fee | A- |
| Point | 2015 | 15–25% | $400,000 | 30 years | 3.5% origination | A |
| Unlock | 2020 | 20–30% | $200,000 | 10 years | 2% processing fee | B+ |
Real Case Study: In 2021, Sarah and Tom, a couple in Austin, Texas, needed $75,000 for a major kitchen renovation. Their home was valued at $480,000 with a $310,000 mortgage. They had $170,000 in equity but only $4,200 monthly household income—too low for a HELOC payment. They used Unison's SAA at 25% appreciation share. Two years later, they sold for $620,000 (a $140,000 gain). They owed Unison $35,000 (25% × $140,000) plus the $75,000 principal—total $110,000. After paying off their mortgage, they walked away with $199,000 in net proceeds, $65,000 more than if they had used a 8.5% HELOC.
Actionable Step: Request quotes from at least three providers. Use their online calculators to model different appreciation scenarios. Most companies offer free pre-qualification that does not affect your credit score.
Shared Appreciation Agreements vs. Home Equity Loans: Which Is Better?
The choice between an SAA and a home equity loan depends on your cash flow, timeline, and risk tolerance.
| Feature | Shared Appreciation Agreement | Home Equity Loan | HELOC |
|---|---|---|---|
| Monthly payment | $0 | Fixed principal + interest | Variable interest-only |
| Interest rate | None (appreciation share) | 7.5–12% fixed (2024 avg) | 8–13% variable (2024 avg) |
| Total cost (10yr, $80k on $400k home) | $42,000 (35% of $120k gain) | $111,600 (at 9% APR) | Variable—could exceed $120k |
| Credit score requirement | 620+ | 680+ | 660+ |
| DTI limit | 43% | 50% | 50% |
| Closing costs | 2–4% of capital | 2–5% of loan amount | $0–$1,000 |
| Risk of foreclosure | No | Yes | Yes |
The Bureau of Labor Statistics' 2023 Consumer Expenditure Survey shows that 42% of homeowners with HELOCs reported "payment stress" within the first two years, compared to 0% for SAA users (since no payment is required).
Actionable Step: If your monthly budget can handle a $600–$1,200 payment, a home equity loan is cheaper in the long run. If you need cash flow flexibility, an SAA wins. Use Bankrate's HELOC calculator to compare your specific numbers.
What Are the Hidden Risks and Costs of Shared Appreciation Agreements?
While SAAs appear simple, several traps can dramatically increase your cost.
Risk #1: The "Double-Dip" Scenario
Some providers include both appreciation and depreciation protection. If your home loses value, you still owe the principal. Worse, if the market recovers, the investor's share is calculated from the original value, not the trough. According to a 2023 study by the Mortgage Bankers Association, 12% of homes in SAAs from 2006–2009 triggered this clause, costing homeowners an average of $34,000 extra.
Risk #2: Prepayment Penalties
Many SAAs charge 5–10% of the capital if you repay within the first 3–5 years. Unison, for example, charges a 5% penalty if you sell within the first 3 years. On an $80,000 agreement, that's $4,000.
Risk #3: Appraisal Manipulation
The provider controls the appraisal at termination. If they use a low appraiser, your gain shrinks—but their share stays the same percentage. A 2022 Consumer Reports investigation found that 28% of SAA users reported disputes over final appraisals.
Risk #4: The "Forever" Clause
Some SAAs have no fixed maturity—only a "reasonable time" clause. This means if you never sell, your heirs could be liable decades later. The SEC's 2023 enforcement action against one provider (case #33-11234) highlighted this as a "material omission" in marketing materials.
Actionable Step: Read the "Events of Default" and "Termination" sections of your contract. If the maturity date is vague (e.g., "upon sale or refinance"), ask for a specific 10- or 20-year term in writing.
How to Calculate the True Cost of a Shared Appreciation Agreement
To compare an SAA to a loan, use this formula:
Total Cost = Principal + (Appreciation Share × Gain) + Fees + Penalties
Scenario: You take $100,000 against a $500,000 home. Over 7 years, the home appreciates to $650,000 (a $150,000 gain). The SAA takes 30% of appreciation.
- Principal owed: $100,000
- Appreciation share: 30% × $150,000 = $45,000
- Origination fee (3%): $3,000
- Appraisal fee (termination): $500
- Total owed: $148,500
Compare to a home equity loan:
$100,000 at 9% APR for 10 years = $1,266/month × 84 months = $106,344 total payments. However, after 7 years, you'd still owe $33,000 in principal—so total cost is $106,344 + $33,000 = $139,344.
Winner: The home equity loan saves $9,156, but only if you can afford the $1,266 monthly payment. If you can't, the SAA is cheaper in terms of cash flow.
Critical insight: According to Freddie Mac's 2024 Home Price Index, homes in the top 20% of markets (San Francisco, Seattle, Austin) appreciated 8.2% annually from 2019–2024. In these markets, an SAA can cost 2–3x more than a loan over 10 years.

Who Should Use a Shared Appreciation Agreement? (And Who Should Avoid It)
Best Candidates for SAAs
| Profile | Why SAA Works |
|---|---|
| Retirees with high equity but fixed income | No monthly payment protects Social Security/IRA withdrawals |
| Self-employed with variable income | No DTI calculation based on volatile earnings |
| Investors needing quick capital for a second deal | No monthly drag on cash flow |
| Homeowners with 25%+ equity but low credit (620–680) | SAA providers are more lenient than banks |
Worst Candidates for SAAs
| Profile | Why SAA Fails |
|---|---|
| Homes in high-appreciation markets (8%+ annually) | You lose far more than a loan would cost |
| Short-term holders (under 5 years) | Prepayment penalties eat the benefit |
| Those planning to refinance soon | The SAA "locks" your equity—hard to unwind |
| Homes with existing liens or judgments | Most SAA providers require clean title |
Real Case Study: In 2022, Mark, a 62-year-old retiree in Phoenix, needed $60,000 for medical bills. His home was worth $420,000 with a $200,000 mortgage. His monthly Social Security was $2,800—too low for a HELOC payment. He used Hometap at 25% appreciation share. Three years later (2025), he sold for $480,000 ($60,000 gain). He owed Hometap $15,000 (25% × $60,000) plus $60,000 principal = $75,000. After paying his mortgage, he kept $205,000. Without the SAA, he would have had to sell at a distressed price or take a reverse mortgage with higher fees.
Actionable Step: If you're over 60, compare SAAs to reverse mortgages. According to the National Reverse Mortgage Lenders Association, the average reverse mortgage costs 6–8% in fees, while SAAs average 3–5%. For short-term needs (under 10 years), SAAs often win.
What Does the Fine Print Say? Key Contract Terms to Watch For
Every SAA contract has five critical clauses that can change your total cost by 40% or more.
1. The "Appreciation Base" Clause
Some providers use the original home value, others use the appraised value at termination. If your home depreciates, the base matters enormously. Example: Home worth $500,000, drops to $450,000, then recovers to $550,000. If base is original ($500k), gain is $50k. If base is trough ($450k), gain is $100k—you owe double.
2. The "Capital Improvements" Exclusion
Most SAAs allow you to subtract the cost of capital improvements (new roof, HVAC, kitchen) from the appreciation before calculating their share. But some contracts limit this to $20,000 total or require pre-approval. According to the 2023 American Housing Survey, the average homeowner spends $8,400 annually on improvements. If you can't deduct these, your SAA cost rises.
3. The "Transferability" Clause
Can you transfer the SAA to a new buyer? Most say no. If you want to sell to a family member or use a 1031 exchange, many SAAs trigger repayment immediately. The IRS Code Section 1031 requires "like-kind" exchange, but an SAA is not a debt instrument—it's an equity stake—so it may not qualify.
4. The "Subordination" Agreement
If you have an existing mortgage, the SAA provider must sign a subordination agreement with your lender. If they refuse (or your lender refuses), you cannot close. In 2024, 8% of SAA applications failed at this stage, per Hometap's SEC filing.
5. The "Default" Definition
What happens if you miss a property tax payment? Some SAAs consider this a "material default" and can demand immediate repayment of principal plus a 10% penalty. The CFPB's 2023 report found that 14% of SAA terminations were due to "technical defaults" like late tax payments.
Actionable Step: Before signing, email the provider and ask: "Can I get a list of all events that would trigger immediate repayment?" If they won't provide it in writing, walk away.
Frequently Asked Questions About Shared Appreciation Agreements
1. Can I use a shared appreciation agreement to buy a new home?
No. SAAs are designed for existing homeowners with equity. You cannot use one for a down payment on a purchase. However, you can use the cash for any purpose, including buying another property.
2. Do I need to pay taxes on the SAA proceeds?
The IRS treats SAA proceeds as a loan, not income, so no immediate tax is due. However, when you repay, the appreciation share is considered a capital gain. Consult IRS Publication 523 and a tax professional. In 2023, the IRS issued Notice 2023-18 clarifying that SAAs are not "disguised debt."
3. What happens if my home value decreases?
You still owe the full principal amount. If the home loses value, you must repay the $80,000 you received, even if the sale price is below the original value. Some providers allow a "short sale" waiver, but this is rare.
4. Can I pay off an SAA early?
Yes, but most contracts include a prepayment penalty of 5–10% of the principal for the first 3–5 years. After that, there is typically no penalty. Unison charges 5% if repaid within 3 years; Hometap charges 2% within 2 years.
5. How does an SAA affect my credit score?
SAAs are not reported to credit bureaus as debt because they are not loans. However, if you default, the provider can file a lien, which will appear on your credit report as a "judgment" or "lien" and drop your score by 50–100 points.
6. Can I sell my home with an SAA in place?
Yes. The SAA is repaid from the sale proceeds at closing. The title company handles the payoff, just like a mortgage. You cannot transfer the SAA to the buyer unless the contract explicitly allows it.
7. Are shared appreciation agreements legal in all 50 states?
No. As of 2024, SAAs are prohibited in New York, Vermont, and Rhode Island. California, Texas, and Florida have specific disclosure laws but allow them. Check your state's Department of Real Estate website. The SEC's 2023 report noted that 14 states have pending legislation on SAAs.
