Most small-balance commercial borrowers never pay for a Phase I. What runs on nearly every file is something lighter, faster, and cheaper: a database screen we order ourselves, which you will probably never hear about again. The Phase I is the escalation, not the default.
Environmental consultants own the search results for this question, and they answer it from the sell side — here is what a Phase I is, here is what it costs, here is our turnaround. That is useful once somebody has already told you to get one. It does not tell you whether anybody is going to.
This page answers it from the lender's side, in the order a borrower actually cares about: will this happen to me, what does it cost me in time, and what makes it more likely.
What happens on every file: the transaction screen
Before anything escalates, there is a baseline, and the baseline is not a Phase I.
Two practical things follow from that.
It is ours to order. Our document checklist — the list of items a borrower or broker actually hands us — does not include an environmental report. You are not expected to show up with one. In most cases you should not go buy one before we ask, because you may be buying the wrong report at the wrong scope for a file that never needed it.
It looks at the neighbors, not just you. The screen assesses the subject property and its surrounding areas. A clean building can sit next door or downgradient from a former fuel site, a plating shop, or a dry cleaner that closed in 1994. Historical records searches surface that. Surrounding-area hits are one of the more common reasons a borrower who is certain their own property is spotless still gets a second round of questions.
What the screen has to come back saying
The pass/fail language is short, and it is not graded on a curve.
"No further action" is the phrase to watch for. In environmental work it is a term of art — it means the reviewing party or agency concluded nothing further needs to be done. A report that identifies an issue and then recommends more investigation is not a "no further action" report, and it will not close the question by itself.
Our guidelines then describe what gets weighed to decide whether a property is eligible at all: the results of the ETS, the property's current and historical uses, the results of an Environmental Screen with Risk Assessment, Environmental Insurance, and a Phase I or Phase II. That is the escalation ladder, written as a single sentence.
Here is the honest reading of that sentence, and it matters: our guidelines contemplate a Phase I or Phase II on any file where the earlier steps do not resolve cleanly, but outside of one specific case they do not publish a numeric or categorical trigger for it. There is no rule in the book that says "property type X always gets a Phase I." What there is instead is a review standard — low risk or no further action — and the discretion to order what it takes to get there.
The one written trigger: No Doc Streamline below 1.15x
There is exactly one place where our guidelines name a Phase I as something that can be called for on a defined population of loans. It was added in July 2026.
Read the words, because the words are doing real work. May be required. At the lender's discretion. This is not a threshold that fires automatically when your DSCR prints 1.14x. It is a written authorization to escalate on a population where two risk factors are already stacked — minimum documentation and thin coverage — and it lists the inputs that inform the call rather than an arithmetic test that decides it.
Anyone who tells you a sub-1.15x No Doc Streamline file "requires" a Phase I is hardening discretion into a rule. It is not one, and we are not going to describe it as one.
How you end up in that population in the first place
Most borrowers do not choose No Doc Streamline. They land in it.
No Doc Streamline is our minimum-documentation program, available on both investor and owner-occupied properties, where the cash flow of the subject property carries the debt. It is also the landing spot when a file misses coverage on a fuller program.
| Program | Coverage requirement | What happens if you miss it |
|---|---|---|
| Investor Complete / Lite Doc | 1.15x DSCR | May be converted to No Doc Streamline |
| Owner-occupied Complete / Bank Statement | 1.20x Global DSC | May be converted to No Doc Streamline |
| No Doc Streamline | 1.00x DSCR, based on the rents the appraiser used to derive value | This is the floor program |
So the sequence that puts a borrower inside the July 2026 provision usually looks like this: the file was submitted as a Complete or Lite Doc investor loan, the underwritten DSCR came in under 1.15x, the file converted to No Doc Streamline to survive — and it arrived in the one program where a Phase I is expressly on the table.
Note the trap in that path. You can be in No Doc Streamline and comfortably above the 1.15x mark; the program's own floor is 1.00x. The Phase I provision is not about being in No Doc Streamline. It is about being in No Doc Streamline and below 1.15x.
No Doc Streamline is not a soft program in other respects, which is worth knowing before you assume the conversion is free.
Maximum LTV on No Doc Streamline is 75% on a purchase and 70% on a rate-and-term refinance or cash-out, against 80% at the top of the standard programs for borrowers at 725 FICO or better. The conversion buys you a closeable file; it costs you leverage and it raises your credit floor.
The five factors that drive the call
The guideline names them. Here is what each one means in practice.
Property use. What the building is used for today, and what it was used for before. This is the single biggest input, and it is the one you can least control on a purchase, because the prior owner's operations are the history.
Environmental risk profile. The output of the screening — the risk rating, the hits, whether they are on your parcel or nearby, how old they are, and whether anything was ever closed out.
Loan size. Our program runs from $100,000 to $2,500,000, with maximum aggregate exposure across all products of $6,250,000. A $160,000 loan on a small strip retail building and a $2.4 million loan carry very different amounts of exposure to the same contamination. The cost of the report has to be proportionate to what is at risk, and on the small end it frequently is not.
Results of third-party environmental screening tools. This is the ETS and anything layered on top of it. In plain terms: what the databases said. Clean database results on a low-risk use are the ordinary reason a Phase I never comes up.
Other relevant factors. Deliberately open. Appraisal observations, the borrower's own disclosures, tenant mix, prior-owner history, and anything the file turns up.
Property types that carry environmental weight
Some of this question is settled before environmental review even runs, because the property type is not eligible in the first place. Our ineligible list is where a lot of the classic environmental risk lives.
| Property type | Status under our program | Environmental note |
|---|---|---|
| Gas stations | Ineligible | Also named as an example of a special-use property |
| Car wash | Ineligible | — |
| Heavy / dirty manufacturing (industrial) | Ineligible | Light industrial is defined as having no heavy machinery, welding operations, cranes, or hazardous materials |
| Marinas | Ineligible | — |
| Golf courses | Ineligible | — |
| Agricultural / farm land | Ineligible | — |
| Campgrounds | Ineligible | — |
| Automotive services | Generally eligible, including major mechanical work | Specific exclusions below |
| Light industrial (under 25,000 SF) | Eligible, Tier II | Definition excludes hazardous materials |
| Warehouse / self-storage | Eligible, Tier II | Traditional self-storage only |
| Dry cleaners, plating, print shops | Not separately addressed in our guidelines | See the note below |
Automotive is where borrowers get surprised, because the headline is friendlier than the fine print.
On dry cleaners, plating shops, print shops, auto body, and similar uses: our guidelines do not name them individually. They fall under "property use" and "current and historical uses," which are inputs to a judgment, not entries on a list. Treating them as automatic Phase I triggers would be inventing a rule we do not have. Treating them as invisible would be worse. The realistic expectation is that a current or historical use with a solvent, fuel, or heavy-metal history makes escalation materially more likely, and that a screen returning hits on that use is unlikely to close on its own.
What the lighter screening actually is
The following is general industry context, not our program's rule, and it is here because borrowers keep getting quoted the wrong product.
Environmental due diligence is standardized by ASTM, and the levels are distinct:
- Transaction screen. A questionnaire-plus-database-and-records product, governed by its own ASTM standard, and considerably narrower in scope than a Phase I. Typically completed in days rather than weeks, and typically a few hundred dollars in small-balance markets. This is the level our baseline requirement sits at.
- Phase I ESA. The full ASTM assessment: records review, site reconnaissance by an environmental professional, interviews, and a written opinion on recognized environmental conditions. No sampling. In small-balance commercial markets these commonly run in the low four figures and take roughly two to four weeks depending on how fast the records vendor and the site visit line up.
- Phase II ESA. Sampling — soil, groundwater, vapor, building materials — ordered when a Phase I identifies something specific worth testing. Cost and timeline are wide open because they depend entirely on what is being chased.
Those cost and timeline figures are general market observation, not a quote from us and not a term in our guidelines. Get an actual quote before you budget.
What it costs you in time
This is the part borrowers underrate. A Phase I is rarely a deal-killer on its own; it is a calendar event.
If you are running a purchase with a defined closing date, a mid-underwriting Phase I request is the thing most likely to force an extension. The report itself has a turnaround, and if it comes back recommending further investigation, you are now looking at a Phase II on top of it — with no reliable way to predict how long that takes.
Practical sequencing:
1. Do not order anything before we ask. Reports have to meet ASTM standards and satisfy the review standard, and a report bought at the wrong scope, or addressed to the wrong party, is money spent for nothing.
2. Disclose the property's history early — including uses you think are irrelevant. Prior uses surfacing late in underwriting is worse than prior uses surfacing at application.
3. If your file is a No Doc Streamline conversion with coverage under 1.15x, raise the environmental question with us at the start rather than waiting to find out. That is the one population where we have written the possibility down.
4. Build contingency into your purchase agreement if the property has any industrial, automotive, or fuel history at all.
Where environmental and appraisal findings meet
The appraisal and the environmental screen are separate reports on separate tracks, but they land on the same desk. Our credit decision explicitly considers third-party reports including appraisals, title reports, and environmental assessments.
Two things worth knowing about the appraisal side, because they compound:
Condition findings have their own consequences. When an appraiser rates a property in Fair condition, the file gets an additional review by our real estate group to determine whether the property is acceptable. Deferred maintenance that rises to a life-and-safety issue may be a reason to decline, and where it is not, evidence of repair may be required before closing. Separately, a property is ineligible if other properties within a two-block radius are vacant, abandoned, or boarded.
Holdbacks will not solve a structural problem. We can hold back for reasonable repairs that improve the property, and a holdback period cannot exceed 180 days — but repairs and renovations that are structural, new construction, or a retrofit of the subject property are ineligible.
The connection to environmental review is practical rather than procedural: a distressed, half-vacant, industrially-adjacent property tends to generate findings on both reports at once, and the file gets harder on both axes simultaneously.
The short version
- Every property gets an Environmental Transaction Screen. We order it. You do not buy it.
- Reports must show low risk or no further action, and must meet ASTM standards.
- A Phase I is an escalation. Our guidelines name it as a possible requirement on one defined population — No Doc Streamline loans with a DSCR below 1.15x — and that requirement is discretionary, driven by property use, risk profile, loan size, screening results, and other factors.
- Some environmentally-loaded property types never get that far, because they are ineligible: gas stations, car washes, marinas, golf courses, heavy manufacturing, and any automotive property with a gas dispenser, an underground storage tank, or a below-ground pit.
- The real cost of a Phase I in small-balance lending is usually calendar, not dollars.
What this page does not do
This page does not tell you whether your specific property will require a Phase I. It cannot, and neither can any page — the determination is discretionary by design and depends on screening results nobody has run yet.
It does not price a Phase I or a transaction screen for you. The cost and timeline figures in the general-context section are market observation, not our quote and not a term of our program.
It does not commit us to ordering, or to not ordering, an environmental report on any file. The guideline language is permissive, and this page preserves that rather than converting it into a promise in either direction.
It does not set out how a contaminated or flagged property gets cured. Our guidelines state the review standard and list the tools; they do not publish a remediation procedure, and we are not going to invent one here.
It is not legal or environmental advice. If you have reason to believe a property has a contamination history, talk to a qualified environmental professional and to your own counsel — the diligence protects your position as an owner, independent of what any lender requires.
Our guidelines are subject to change, and exceptions and case-by-case judgments exist throughout. If you want to know what your actual file would face, bring us the address, the current use, and whatever you know about what was there before.
