โœ… CONDITIONAL GO

Mayfair is a viable deal with strong capital efficiency, but requires permit resolution and tight execution. Proceed with conditions.

โš ๏ธ Key context: At 19.1% LP IRR, Mayfair is the weakest return in JAK's portfolio (other deals target 22โ€“26%). The trade-off: JAK only puts in $800K of equity for a $37M project. Capital efficiency is the story here, not raw returns.
1
Do the Numbers Work?
YES โ€” WITH CAVEATS

The core numbers are solid and well-documented by Novak:

The catch: 19.1% is the weakest return in JAK's portfolio. But the $800K equity requirement makes this extremely capital-efficient โ€” $1.9M total return on $800K invested is a 2.38x adjusted EM.

2
Is the New Braunfels SFR Market Thesis Solid?
YES โ€” STRONG

New Braunfels is one of the strongest growth markets in Texas. The thesis is sound.

๐Ÿ“ Location thesis: Unlike JAK's Austin deals (which face 14.2% vacancy and -4.5% rent growth), New Braunfels is in a different cycle โ€” growing rapidly, less overbuilt, and benefiting from Austin overflow. This is a genuine diversification play.
3
Permit Risk โ€” How Real Is It?
MODERATE โ€” NEEDS CLARITY

The project is fully designed but not yet permitted. First-round permit comments have been received but not resolved.

โš ๏ธ Critical question: What are the specific permit comments? The difference between "move the fire hydrant 20 feet" and "reduce density by 30%" is the difference between a 2-month fix and a deal-breaker. This must be clarified before committing capital.
4
JV Structure & Loan Timeline Pressure
WATCH โ€” TIMING RISK

The current $1.75M loan (Novak's existing debt) has been extended through August 2026 with no debt service until September 2026. This creates both an opportunity and a hard deadline.

Key question: Can Novak extend the loan past Aug 2026 if needed? What are the terms? Is there automatic extension language or does it require fresh negotiation?

5
Black Cat Construction โ€” Cost Overrun Exposure
MODERATE RISK

Black Cat is the construction partner for 140 SFRs at ~$155K/unit ($21.7M construction + $2.5M site work = $24.2M total).

โš ๏ธ Contingency concern: At 2% ($550K), there's essentially no room for error on a $24.2M construction program. A single material spike or weather delay could consume the entire contingency. Recommend confirming: (a) GMP contract with Black Cat? (b) Cost-plus with cap? (c) Who absorbs overruns โ€” Black Cat or JAK?
6
JAK's $800K Equity โ€” Capital Efficiency or Under-Commitment?
NET POSITIVE โ€” SMART STRUCTURE

JAK's F&F equity is only $800K on a $37M project. That's 2.2% of TPC. This is either brilliant capital efficiency or a sign that JAK has limited skin in the game.

Net assessment: For a F&F investor, this is an attractive risk/reward. $800K of exposure for a 38% adjusted IRR in a well-defined SFR project with a confirmed exit thesis. The capital efficiency is a feature, not a bug.

7
GO / NO-GO Verdict
CONDITIONAL GO

CONDITIONAL GO โ€” Mayfair is a viable deal with attractive capital efficiency, but it's not a slam dunk.

Why GO:

Why CONDITIONAL (not unconditional):

Before committing $800K:

Portfolio Context

Mayfair sits at the lower end of JAK's return spectrum but offers unique advantages:

Metric Mayfair JAK Target Range
LP IRR19.1%22โ€“26%
Dev Spread150 bps200+ bps
F&F Equity$800K$2โ€“5M typical
Adjusted IRR38.32%โ€”
MarketNew Braunfels (diversification)Austin metro

Conclusion: Mayfair trades lower absolute returns for exceptional capital efficiency and geographic diversification. For an $800K check with a 38% adjusted IRR, this is a compelling addition to the portfolio โ€” but only if the four conditions above are met.
