52TEN Fund III review: a transparent mobile home park sponsor with a 10-year commitment

What the fund is

52TEN Fund III, LP is a mobile home park fund that buys higher-quality, value-add and core-plus manufactured housing communities in markets with above-average home values and strong demand for affordable housing. It targets parks worth $15 million to $40 million each.

Unlike 52TEN’s earlier funds, Fund III is designed as a “legacy hold.” The plan is to buy parks, capture the tax benefits, finish repositioning each property, then refinance to return capital and distribute cash flow indefinitely, rather than selling after a few years. 52TEN says it focuses on properties that are not formally for sale, sourced through relationships with owners and brokers.

The sponsor

52TEN was established in 2016 and is based in Scottsdale, Arizona. According to its public FAQ, 52TEN, LLC is owned solely by its two principals, Jesse (Jack) Martin and Nathan (Nate) Pattee, who are also the only authorized signers and wire approvers on its bank accounts. Fund administration is handled by an outside firm, RedCedar.

52TEN, LLC is registered with the SEC as an investment adviser (CRD 330071) and filed its most recent Form ADV in March 2026, reporting five private funds with total gross assets of about $58 million. Invest Clearly lists the firm’s assets under management at $145 million, a figure that likely reflects total property value rather than fund assets.

The firm’s FAQ states that neither 52TEN nor its principals have filed for bankruptcy, been sued by investors, employees or vendors, or faced criminal actions. These are self-reported answers, but publishing them is unusual and useful for investors.

SEC filings

Terms

• Structure: Regulation D Rule 506(c); accredited investors only.
• Target fund size: $60 million.
• Target return: 13–15% IRR, per its Invest Clearly listing.
• Minimum investment: $100,000 on Invest Clearly; Fund III’s original Form D lists $1,000,000. Ask which applies.
• Timeline: buying for up to 18 months after the initial closing in July 2026, then a 10-year hold.
• Liquidity: return of capital or liquidity at intervals when properties are refinanced; no scheduled redemptions.
• Objectives: tax benefits, income and capital appreciation.

52TEN’s website says Fund III opened in June 2026, while its Form D was filed in January 2025 and PitchBook lists the fund with a 2025 vintage and “closed” status. These are likely timing and data differences rather than problems, but investors should confirm the fund’s status.

Properties so far

• Paradise North Estates, Phoenix: a 148-lot, 55+ manufactured housing community, 98% occupied, announced as Fund III’s first acquisition and described as fully subscribed.
• North Meadows, Greensboro, North Carolina: a stabilized 203-lot community announced as under contract as the fund’s second property.

Fund III appears to raise commitments property by property, with investors invited to fund each acquisition.

Track record

52TEN’s earlier vehicles, Funds I and II and three single-deal partnerships, have raised more than $58 million in total according to SEC filings. Its properties have included Hidden Oasis Estates, Country Glen Estates in Georgetown, Texas, and Villa Estates in Omaha, Nebraska. Co-founder Jack Martin has said the firm’s entire portfolio is performing at 116% of its original projections. 52TEN publishes a track record page covering all properties, which investors should review alongside audited statements.

Claims versus records

Key risks

• Very long hold: capital is committed for roughly 10 years or more, and liquidity depends on refinancing, which depends on future interest rates.
• Rent regulation and reputation: mobile home park owners in several states have faced lawsuits, investigations and new laws over lot rent increases. 52TEN says it takes a balanced approach, improving communities before aligning rents with the market.
• Concentration: with a $60 million target and $15–40 million parks, the fund may own only a handful of properties.
• 55+ community dynamics: age-restricted communities have specific regulatory and demand considerations.
• Self-reported performance: returns are not publicly audited.

What investors say

We found no complaints, lawsuits or regulatory actions involving 52TEN, Jack Martin or Nate Pattee, including in news coverage of mobile home park rent disputes.

Strengths and concerns

Strengths

• SEC-registered adviser with current Form ADV filings.
• Independent fund administration and published banking controls.
• A detailed public due diligence FAQ.
• Two prior funds and three single-deal vehicles raised and documented in SEC filings.
• Strong verified investor reviews and no complaints found.
• Named properties with strong occupancy.

Concerns

• A 10-year-plus hold with liquidity only at refinancing events.

• Inconsistent minimum investment and fund status across sources.
• Sector exposure to lot rent regulation and resident disputes.
• Urgency-based marketing, such as “the window is closing.”

Who it suits

Questions to ask before investing

1. Is the minimum investment $100,000 or $1,000,000?
2. What are the fund’s fees, and how is the general partner paid during a long hold?
3. Can you share audited financial statements for Funds I and II?
4. How will lot rent increases be handled at Paradise North Estates and North Meadows?
5. What happens if refinancing is not possible when investors expect liquidity?

What would change our verdict

• Audited results for Funds I and II;
• consistent, published fund terms including fees;
• a defined liquidity mechanism beyond refinancing events.

With audited results and published fees, this fund could move into the Strong band.

What we couldn’t verify

• Fund III fees and the full offering memorandum.
• Audited returns for prior funds.
• Capital raised for Fund III since its original filing.
• Lot rent history at 52TEN properties.
