Questions

Before you begin


Who can invest?

Accredited investors as defined by the SEC. For example, individual income above $200,000 (or $300,000 jointly) in each of the last two years, or net worth above $1 million excluding a primary residence. Cornerstone confirms each investor's status before accepting any investment.

Does completing the questionnaire mean I'm eligible?

No. Your answers help us prepare for the call. Accredited status is confirmed separately, through the offering's verification process, before any investment. VERIFY process wording

What is the focus of Cornerstone's investment strategy?

Real estate for healthcare, mainly residential treatment centers for children and adolescents. The current properties are in Fulton, Missouri and Vancouver, Washington. VERIFY target markets: the previous page also named Virginia and Texas

How are properties selected?

On the need for treatment capacity in the local market, fit with the mission, and whether the building and its lease can support the offering's targets. Each acquisition is underwritten before purchase. VERIFY selection criteria

How does Cornerstone approach risk?

Cornerstone's stated approach is to hold real estate with borrowing kept at or below half of the property's value, to underwrite each property before acquisition, and to lease to operators on long terms. VERIFY current loan-to-value and lease terms None of this removes risk. Real estate investment carries substantial risk, including loss of the entire amount invested. The risk factors in the offering documents control.

What returns does the offering target?

Cornerstone's current materials show a target preferred return of 18% to 30% a year, rising with the amount invested, with distributions paid quarterly. These are targets based on assumptions that may not hold. Actual results may differ materially, and no assurance is given that any target will be achieved. The private placement memorandum sets the terms. VERIFY against the current PPM

What is the investment horizon?

There is a six-month minimum lock-up. After that, the offering documents set out how and when redemption requests are handled. VERIFY redemption terms The underlying leases are long-term, so the offering is designed to be held for income rather than traded. VERIFY lease term: the previous page stated a 25-year triple-net lease

Is there a commitment on the first call?

None. The call is an introduction. You will receive the offering documents to review before any decision.

How can I follow my investment?

Investors receive periodic reporting through Cornerstone's investor portal and can contact the investor relations team directly. VERIFY portal and reporting cadence

How does the investment support the community?

The buildings house residential treatment and mental health services for children and adolescents, including children in foster care. Facilities of this kind also create local clinical and support jobs.

How is the money used?

To acquire and prepare buildings for youth mental health treatment centers. The offering documents set out the full use of proceeds.
