How We Order This List

What sets the order, and what the measured score does and does not tell you

We reviewed 8 firms that advertise investment underwriting, buy-side diligence or family office advisory in Miami and ordered this list by mandate fit: the investment types each firm actually underwrites, the check sizes it works at, and how directly a principal works the engagement. That is why a national transaction advisory practice and an independent principal-led underwriter can sit near each other here. The measured AI visibility figure sits alongside that judgment rather than replacing it, and it rewards firms that have been publishing longest, not the ones that fit a given deal best. No firm paid for its position on this page. ProCloser may have, or enter into, referral relationships with firms covered on this site; see our Advertiser Disclosure.

Signal 1 · Measured

AI Visibility Score

The share of AI answers naming each firm when we ask 10 investment underwriting questions about Miami across Google AI Mode and ChatGPT (20 answers, September 2026). It measures published reach, so long-established platforms score highest and a newer independent practice scores low even when the mandate fit is strong.

Signal 2 · Measured

Review Score

Aggregate ratings across Google and the ProCloser.ai verified review system. Firms serving a handful of family offices under confidentiality often carry no public reviews at all, and we show that as "No reviews yet" rather than penalizing it.

Signal 3 · Editorial

Mandate Fit

What each firm actually underwrites: operating companies, real estate, startups, credit or structured deals, the check sizes it works at, and whether a principal signs the memo. This is our judgment, informed by each firm's own published record, and it is what sets the order above.

Investment Underwriting Market Overview: Miami, FL

Underwriting work differs by what is being bought. The table below shows what a proper underwriting engagement covers for each investment type, so you can check that a firm's scope matches the deal in front of you.

Investment typeWhat underwriting covers
Operating company acquisitionQuality of earnings, working capital, customer and contract review, management assessment, structure and downside cases
Commercial real estateRent roll and lease review, market and comparable analysis, debt sizing, sponsor and operator diligence, waterfall review
Startup and angel investmentsCap table and terms, unit economics, runway and next-round assumptions, founder references
Private credit and structured dealsCollateral and coverage, covenants, waterfall and priority, servicer or platform diligence
Portfolio and investment processMandate definition, investment committee materials, monitoring and reporting, governance

Regulatory and Licensing Environment

Whether an underwriting advisor needs to be registered depends on what it does. Giving advice about securities for compensation as a business generally requires registration as an investment adviser with the SEC or the applicable state securities regulator, and firms that manage or advise on a family's portfolio on an ongoing basis are usually registered. Project-based due diligence, quality of earnings and underwriting support for a specific deal is typically consulting work outside that requirement, and many firms on this page work that way. Single-family offices themselves commonly rely on the SEC's family office rule. Confirm which model a firm uses and check SEC IAPD before signing.

Investment Underwriting Fees in Miami, FL

Underwriting and family office advisory fees follow four patterns. None of the 8 firms on this page publishes a rate card; every one quotes on request.

Fee structureWhere you see it
Fixed fee per underwriting or diligence engagementBuy-side diligence, quality of earnings, CRE underwriting on a defined deal
HourlyPrincipal-led underwriters and investment committee support on a variable workload
Monthly retainerOngoing deal screening, pipeline management and portfolio governance for a family office
Percentage of assets advisedMulti-family offices and outsourced CIO firms that also manage the portfolio

The one structure to avoid on underwriting work is a fee that depends on the deal closing. An underwriter paid on close has a reason to say yes. Every firm on this page should confirm in writing that its underwriting fee is not contingent.

How to Choose an Investment Underwriting Advisor in Miami, FL

  • Independence first: ask whether the firm earns anything if the deal closes, from you or from the other side. The answer should be no for underwriting work, and it should be in the engagement letter.
  • Match the asset: underwriting a self-storage portfolio and underwriting a software acquisition are different jobs. Every firm on this page publishes what it underwrites, and the honest ones say what they do not.
  • Ask who signs the memo: the person who presents to your investment committee should be the person who did the analysis. At larger firms ask which partner owns the engagement.
  • Ask what happens after close: some firms only underwrite, others stay on for monitoring, reporting and governance. If you have no in-house team, the second kind saves you a second search.

Frequently Asked Questions

Common questions about hiring an investment underwriting or family office advisor in Miami, FL.

Who provides underwriting support for a family office making direct investments in Miami?+−
Independent advisory firms that do buy-side diligence, quality of earnings and structuring for investors, plus a small number of principal-led underwriters with institutional backgrounds. The firms on this page were verified against their own websites for Miami presence and a named direct-investment or diligence practice. Wealth managers that only allocate to public funds are not included.
Can these firms underwrite a commercial real estate investment for a passive investor?+−
Several can. CRE underwriting covers the rent roll and leases, the market and comparable sales, the debt sizing, the sponsor's track record and the waterfall you are being offered. Ask the firm for a sample underwriting memo on a comparable asset type before you engage, and confirm it has no relationship with the sponsor.
Do I need a registered investment adviser to underwrite a deal?+−
Not for a project-based underwriting or diligence engagement on a specific deal, which is generally consulting work. You do if the firm will advise on your portfolio on an ongoing basis for a fee. Some firms on this page are registered and offer both. Check SEC IAPD and ask which model applies to your engagement.
How much does buy-side underwriting cost?+−
The asset, the size of the deal and whether the work is a defined scope or ongoing support set the fee. Most firms charge a fixed fee per engagement or an hourly rate, and family offices with steady deal flow often move to a monthly retainer. What matters more than the number is that no part of the fee depends on the deal closing.
How is this Miami investment underwriting advisor list ordered?+−
ProCloser.ai orders this list by mandate fit: the investment types each firm actually underwrites, the check sizes it works at, and whether a principal signs the memo. One measured signal, an AI visibility score, is published beside every firm and informs the order rather than setting it. The list was verified against each firm's own website in September 2026.
