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.
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.
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.
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.
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.
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.
