The one-sentence version

A home equity investment (HEI), also called a home equity agreement (HEA) or shared equity agreement, is a contract where an investment company gives you a lump sum of cash now and in return gets a slice of what your home is worth later. You make no monthly payments and pay no interest. Instead, you settle the whole thing in one payment years down the road, usually when you sell, refinance, or reach the end of the term.

Key idea: an HEI is not a loan. A loan charges interest on money borrowed. An HEI sells a share of your home's future value. That is why its cost depends so heavily on how much your home appreciates, and why it is so hard to compare offers without doing the math.

How an HEI works, step by step

  1. You apply. The company checks your home's value, how much equity you have, and your credit. Requirements are usually looser than a bank's (some accept credit scores around 500), and there is typically no income test, because you are not making payments.
  2. They make an offer. You are quoted a cash amount, usually from about $15,000 up to several hundred thousand dollars, limited to a slice of your home's value (commonly 15% to 27%) and to how much total debt the home already carries.
  3. Fees come out. An origination or processing fee, commonly about 3% to 5% of the investment, plus appraisal and closing costs, is deducted, so the cash you receive is less than the headline number.
  4. You get the cash. No monthly bill arrives. Nothing is due month to month.
  5. You settle later. At the end of the term (10 years with some providers, up to 30 with others) or when a triggering event happens, such as a sale, a refinance, or choosing to buy the company out, you pay the settlement amount set by the contract.

A worked example

Say you take $100,000 against a $750,000 home with a $300,000 mortgage, and settle 7 years later after the home appreciates 4% a year. Applying each major provider's published terms, our model puts the settlement at roughly $237,000 to $263,000. That works out to an effective cost of about 14% to 16% a year on the cash you actually received, compared with about 8.5% for a typical HELOC. Your own offer will differ, which is why you should run your numbers.

What an HEI actually costs

Providers rarely put their cost in a single number. It has five moving parts:

The number that makes offers comparable: convert every deal into an effective annual cost, the yearly rate at which the cash you received would have to grow to equal what you settle for. That single number lets you line up an HEI against a HELOC or any loan. Our calculator does this for every major provider at once.
Two traps to test before you sign. First, an HEI costs more the faster your home appreciates, so run a high-growth scenario. Second, because of multipliers and discounted starting values, most HEIs still cost real money even if your home is flat, so run a zero-growth scenario too.

For people who qualify at a reasonable rate and can manage a payment, a HELOC or home equity loan is usually cheaper and more predictable. An HEI earns its place when a monthly payment is not workable, when income or credit make a HELOC hard to get, or when you specifically want to trade future upside for zero monthly cost today.

Frequently asked questions

Is a home equity investment a loan?

No. There is no interest and no monthly payment. You are selling a share of your home's future value, which is why the cost depends on appreciation rather than a rate.

How much does an HEI really cost?

Using the major providers' published terms, our model puts the effective cost at roughly 14% to 16% a year for a home appreciating 4% a year over seven years, compared with about 8.5% for a typical HELOC. With no appreciation at all, the range is roughly 3.5% to 11.5% a year depending on the provider's structure. Your offer will differ, so run your own numbers.

Do I need good credit or income?

Requirements are generally looser than a HELOC. Some providers accept credit scores around 500 and there is typically no income test, but minimum equity and home-value limits still apply.

Can I still sell or refinance my home?

Yes. The HEI is settled at that point out of the proceeds, and the company's interest is recorded against the property until then.

How do I compare offers fairly?

Convert each offer to an effective annual cost for your expected appreciation and time horizon. Our calculator does this across every major provider at once, and HEI Compare lays the providers out side by side.

What happens if my home loses value?

Many HEIs share the downside, so you may settle for less than you received. How much protection you get depends on the provider's structure and starting value, so confirm how losses are handled in your agreement.
