The research in brief

Deephaven Mortgage is a good fit for self-employed homeowners whose bank deposits are stronger than their tax returns, because its Equity Advantage HELOC accepts 12 months of personal or business bank statements in place of tax returns ^[17]. Five of seven platforms named Deephaven during ranking discovery, with an average listed rank of 3.8 and a best rank of 2. The strongest reason to consider it is a dedicated bank-statement HELOC path with first- and second-lien options. The main limitation is that Deephaven lends through wholesale and correspondent partners only, publishes no borrower-specific rates, and its public materials conflict on maximum line amounts and product structure.

Why Deephaven Mortgage Qualified for This Study

Questions explored

Is Deephaven Mortgage a good choice for self-employed income documentation for HELOC approval?
How many AI platforms named Deephaven Mortgage for self-employed HELOC approval?

Deephaven qualified because it is one of the few lenders in this study with a named, self-employed-specific bank-statement HELOC program rather than a generic non-QM mortgage menu. Five of seven platforms named it during ranking discovery, and its best listed rank was 2 (Gemini). Platform fit ratings split: Claude, Gemini, and Grok rated it a strong fit; ChatGPT, Perplexity, and Kimi rated it good; DeepSeek rated it uncertain.

The qualification is not unanimous. Deepseek, which ran without search enabled on 2026-02-06, could not verify any HELOC product on Deephaven's official site and treated the ranking-stage product labels as unverified ^[2]. That is a research-capability gap as much as a factual conflict, but it is disclosed here rather than smoothed over.

Deephaven is a non-QM specialist whose stated focus is borrowers outside agency guidelines, which is the population this use case describes ^[2]. The company also appears in independent trade coverage as an active home-equity expansion story across 2025 and 2026 ^[30].

The mortgage offering in focus

Questions explored

Which Deephaven Mortgage product should a self-employed borrower choose for bank-statement HELOC approval?
Does the Deephaven Mortgage Equity Advantage HELOC accept business bank statements instead of tax returns?

The relevant product is the Equity Advantage HELOC, also marketed as the Equity Advantage Non-QM HELOC and, in some materials, a digital HELOC for Self-Employed Borrowers. Its defining feature for this use case is that self-employed borrowers can qualify using 12 months of personal or business bank statements in lieu of tax returns ^[17].

Company materials describe the product as a standalone HELOC available in first- and second-lien positions, with full documentation, bank statements, and assets all accepted as income-verification paths ^[17]. A company-published scenario describes income calculated from 12 months of bank statements instead of tax returns ^[19]. Independent trade coverage reports the same 12-month bank-statement underwriting and a 2026 expansion ^[30].

Two structural caveats matter for a buyer. First, the official product page describes the line as fixed-rate, fully disbursed at funding, with 5-, 10-, 15-, or 30-year terms — which is not how a conventional open-draw HELOC behaves ^[17]. Second, other sources describe a 5-year interest-only draw with a 30-year maturity and 25-year amortization ^[26]. Those two descriptions are not reconciled in the public materials, and the buyer should confirm which structure applies to their scenario.

What the AI Platforms Agreed About

Questions explored

What do AI platforms agree on about Deephaven Mortgage for self-employed HELOC approval?
Is Deephaven Mortgage's bank-statement HELOC available as a second lien?

The clearest agreement is on the core mechanism: Deephaven's Equity Advantage HELOC accepts 12 months of personal or business bank statements for self-employed borrowers instead of tax returns. This was supported by ChatGPT, Claude, Grok, Perplexity, and Gemini ^[17].

Platforms also broadly agreed that the product is positioned for borrowers who cannot qualify under traditional agency guidelines, and that it can be used as a second lien to preserve an existing low-rate first mortgage ^[30].

A third area of agreement is distribution: Deephaven operates through wholesale and correspondent partners rather than direct consumer retail lending, and its materials are directed at licensed mortgage professionals ^[6]. Buyers should expect to work through a broker or correspondent lender.

Finally, platforms agreed that public pricing is thin. No platform located a borrower-specific rate sheet, APR, or complete fee schedule for the bank-statement path ^[4].

Where the AI Platforms Disagreed or Were Uncertain

Questions explored

What is the maximum line amount on the Deephaven Mortgage Equity Advantage HELOC?
Is the Deephaven Mortgage Equity Advantage HELOC a revolving line or a fully disbursed fixed-rate loan?

Maximum line amount is the sharpest conflict. The official product page states $25,000 to $400,000 ^[17]. A May 2026 trade report describes an expansion to a $50,000 minimum and $1 million maximum ^[30]. A separate Deephaven page cited by Perplexity states $50,000 to $500,000 ^[9]. Google's sources describe $50,000 up to $1,000,000 ^[25]. These figures cannot all be current for the same program version.

Product structure is the second conflict. The official page describes a fixed-rate, fully disbursed line with a set term ^[17], while other sources describe a variable-rate HELOC with a 5-year interest-only draw ^[26]. Deepseek found no HELOC product at all on the official site ^[2].

Credit and equity thresholds also vary by source. Reported minimum FICO ranges from 620 for co-borrowers to 660 for primary residences and 700 for investment properties ^[15]. Reported maximum CLTV ranges from 85% to 90% for primary residences ^[17].

Approval speed is unverified across platforms. Company materials advertise a digital process and a Quick Pricer tool, but no platform established a guaranteed approval or funding timeline ^[17]. One independent profile reports company turn-time targets of roughly 24-hour quote and 48-hour underwriting on non-QM loans, but that is a first-lien operational claim, not a verified HELOC timeline ^[21].

Mortgage features for this borrowing need

Questions explored

What income documentation does Deephaven Mortgage accept for a self-employed HELOC?
Does Deephaven Mortgage allow a first-lien HELOC for a free-and-clear home?

The bank-statement path is the central feature. Deephaven accepts 12 months of personal or business bank statements in lieu of tax returns for self-employed borrowers ^[17]. A related guideline requires the borrower to be self-employed and the business to have existed for at least two years on the referenced bank-statement path ^[14].

Beyond bank statements, company materials reference asset utilization and a 1.1x DSCR option for investment properties, plus first- and second-lien availability ^[10]. One company page states the product is ideal for self-employed borrowers who cannot qualify using tax returns ^[8].

Reported eligibility parameters include maximum CLTV of 90% for primary residences, 85% for second homes, and 75% for investment properties, with DTI allowed up to 50% ^[32]. LLC vesting is reported as permitted for investment properties ^[30].

Geographic coverage is reported at 45 states including Texas as of a May 2026 expansion ^[30]. The published matrix lists no primary or second-home availability in Massachusetts and West Virginia, and no availability in New York or Hawaii lava zones 1 and 2, with additional Texas requirements ^[13]. Google's sources state no New York properties ^[10].

Valuation can use an AVM, with a $180 BPO/residential evaluation fee when AVM requirements are not met, included in the loan total ^[13]. Prepayment penalties are stated as not allowed in the published matrix ^[13].

Rates, fees, and ongoing costs

Questions explored

How much does a Deephaven Mortgage bank-statement HELOC cost, and what fees apply?
Does Deephaven Mortgage charge a rate premium for bank-statement income documentation?

No platform verified a borrower-specific rate, APR, or complete fee schedule for the bank-statement HELOC path. Pricing confidence was rated low by ChatGPT, Claude, Perplexity, Kimi, and DeepSeek ^[4].

The only quantified cost found is the $180 BPO/residential evaluation fee that may apply when AVM requirements are not met, included in the loan total ^[13]. Interest, closing, title, recording, credit, valuation, and origination costs depend on the scenario and state ^[13].

On rate level, one independent trade source reports non-QM rates in the 8%–9% range depending on loan type, LTV, and credit score, but does not isolate a bank-statement premium ^[31]. Kimi cites an industry pattern of at least a 1 percentage point premium for alternative-documentation HELOCs generally, not a Deephaven-specific figure ^[23]. Google's sources reference rate adjusters potentially up to 50 basis points or higher over prime for bank-statement qualification, which is a platform-reported estimate rather than a published rate sheet ^[10].

On contract terms, the published matrix states prepayment penalties are not allowed ^[13]. Reported terms include 5-, 10-, 15-, or 30-year fixed terms with full disbursement at origination ^[17], and separately a 5-year interest-only draw with 30-year maturity ^[26]. Annual, inactivity, draw, early-closure, and broker fees were not verified from public materials ^[13]. Deephaven states that programs and rates are subject to change and that pricing tools are preliminary and not a lock or credit decision (Evidence ID openai:c5, official:C1).

Best Suited For

Questions explored

Who is the Deephaven Mortgage Equity Advantage HELOC best suited for?
Is Deephaven Mortgage a good fit for a self-employed borrower with low taxable income but strong deposits?

Deephaven is best suited to self-employed borrowers whose bank deposits are strong but whose tax-return income is reduced by business deductions ^[17]. It also fits borrowers who want a first- or second-lien equity product while preserving an existing low-rate first mortgage, and free-and-clear homeowners who need a first-lien HELOC ^[5].

It fits borrowers who can satisfy bank-statement, credit, CLTV, DTI, property, and lender-channel requirements, and who are willing to work through a participating broker or correspondent ^[6]. Company case examples describe restaurant owners and small business owners approved using business bank statements without tax returns ^[7].

Borrowers with higher line needs may also fit, given reported maximums up to $1 million in 2026 materials, subject to the conflict described above ^[27].

Probably Not Best Suited For

Questions explored

Who should not choose Deephaven Mortgage for a self-employed HELOC?
Is Deephaven Mortgage suitable for a borrower who wants a traditional revolving HELOC?

Deephaven is probably not the best fit for borrowers who need a conventional open-draw revolving HELOC, because the official product page describes a fixed-rate, fully disbursed structure with a set term ^[17]. Borrowers who need transparent consumer-direct pricing before applying are also poorly served, since the materials are aimed at licensed professionals and no public rate sheet exists ^[4].

Borrowers with low bank deposits, unstable business cash flow, high CLTV, weak credit, or properties in excluded states fall outside the reported parameters ^[13]. Borrowers with less than 12 months of verifiable statements or a business under two years old may not qualify on the bank-statement path ^[15].

Borrowers who qualify conventionally and can obtain materially lower pricing from a bank or credit union should compare before proceeding ^[17]. Borrowers needing a line under $50,000 may also be excluded by reported minimums ^[25].

When Another Option May Be Better

Questions explored

What is a better alternative to Deephaven Mortgage for a self-employed borrower who needs a true revolving HELOC?
When should a self-employed borrower choose a conventional lender over Deephaven Mortgage?

A conventional bank or credit union may be better when it will accept the borrower's documented income and provide a lower APR, lower fees, or a traditional revolving-draw structure ^[17]. A true revolving line with an undrawn balance is a specific case where a different lender may be required, given the conflicting structure descriptions ^[17].

Another non-QM lender may be better when it offers more transparent bank-statement pricing or more flexible business-income calculations ^[17]. Borrowers who need direct consumer retail lending without a broker intermediary should look elsewhere, since Deephaven operates wholesale and correspondent only ^[6].

Borrowers with a FICO below 620, a property in New York, a line need under $50,000, or a preference for dealing directly with a retail bank should consider alternatives ^[25]. Borrowers whose income is better shown through profit-and-loss statements than bank deposits may also find a better fit elsewhere, since the reviewed sources do not confirm a P&L path for this product ^[31].

This review sits inside a broader comparison of lenders for Self-employed income documentation for HELOC approval, where competing options are evaluated on the same criteria.

Questions to ask before choosing a lender

Questions explored

What should a buyer confirm with Deephaven Mortgage before signing a bank-statement HELOC contract?
Which broker or correspondent should a self-employed borrower use to access Deephaven Mortgage?

Confirm whether the current product is a true revolving HELOC or a fixed-rate, fully funded closed-end structure ^[17]. Confirm the current minimum and maximum line amounts for your state, lien position, occupancy, and property type, given the $400,000, $500,000, and $1 million figures in circulation ^[17].

Confirm whether 12 months of personal statements, business statements, or either will be accepted, and what deposit haircut or expense factor applies ^[17]. Confirm the business ownership percentage, seasoning, tax-return, P&L, CPA letter, or business narrative requirements ^[14].

Request the interest rate, APR, points, lender credits, and any pricing adjustment applied specifically to bank-statement income ^[4]. Request an itemized list of appraisal or AVM, BPO, title, recording, credit, origination, broker, annual, inactivity, draw, and early-closure fees ^[13].

Confirm the exact FICO, DTI, CLTV, reserve, occupancy, lien-position, and property requirements ^[13]. Confirm whether a participating broker or correspondent is required and who will service the loan after closing ^[6].

Ask for the realistic time from complete application to approval, closing, and funding, since no verified timeline exists ^[17]. Ask about state-specific cooling-off, rescission, homestead, or recording requirements, particularly in Texas ^[13]. Ask whether the current program allows debt consolidation to qualify, co-borrowers, LLC vesting, and free-and-clear first-lien borrowing ^[17].

The consensus assessment

Deephaven Mortgage is a good fit for self-employed income documentation for HELOC approval, but not a definitive best fit without a lender-issued scenario quote and current matrix. Five of seven platforms named it, with an average listed rank of 3.8 and a best rank of 2. It is unusually relevant when self-employed income is stronger in bank deposits than on tax returns, particularly for borrowers seeking a second lien or a first lien on a free-and-clear property.

The unresolved items are material: conflicting public maximum line amounts, conflicting descriptions of whether the line is revolving or fully disbursed, no published borrower-specific pricing, and a wholesale-only distribution model. Buyers should compare the resulting APR and total fees against conventional and competing non-QM HELOC offers and resolve the conflicting public terms before proceeding.

How This Review Was Produced

This review was produced from platform-reported research collected on 2026-09-29 for the use case "Self-employed income documentation for HELOC approval." Seven platforms evaluated fit: ChatGPT, Claude, Gemini, Grok, Kimi, Perplexity, and DeepSeek. Five of those seven named Deephaven Mortgage during ranking discovery. Each platform supplied its own citations, fit rating, strengths, limitations, pricing notes, and verification questions.

Platform fit ratings were: Claude strong, Gemini strong, Grok strong, ChatGPT good, Perplexity good, Kimi good, and DeepSeek uncertain. No platform conducted independent verification of Deephaven's claims, and no platform tested the product. Citations are platform-reported evidence, not independently verified facts.

Research limitations

Platform-reported research dates differ from the authoritative run date of 2026-09-29. Deepseek's research date was 2026-02-06 and its search was not enabled, which limits its ability to confirm current product availability; its uncertainty should be read with that constraint in mind.

Company-owned citations materially outnumber independent citations in the supplied evidence, so company claims should not be described as independently verified. The supplied URLs were collected from platform responses and were not independently validated at the writing stage.

Public materials conflict on maximum loan amount, product structure, credit thresholds, and CLTV, and this review preserves those conflicts rather than resolving them. No platform established a guaranteed approval, underwriting, or funding timeline. No platform published a borrower-specific rate, APR, or complete fee schedule. The exact bank-statement deposit calculation, expense factor, eligible deposits, business seasoning, ownership requirements, and treatment of transfers and cash deposits are not established in the reviewed public materials.

One platform noted a 2024 Consumer Financial Protection Bureau enforcement action involving Deephaven Mortgage; the announcement describes the company's business as non-QM mortgage lending ^[28]. Buyers should verify any current regulatory conditions directly.
