The Quick Read: You hold a DSCR lender to locked terms by getting the lock, the term sheet, and the pricing assumptions in a signed written document, matching its expiry to the contract’s closing date with room to spare, and knowing exactly which file changes can legitimately reprice the loan. A lock protects pricing only while the file stays inside the assumptions it was built on. Those assumptions are the appraised value, the market rent, the credit profile, the entity documents, and the property type.
- Ask for the lock in writing, with start date, expiry date, loan amount, leverage tier, coverage tier, and prepayment structure.
- Set the lock to expire well after the contract’s closing date, not on it.
- Know the triggers: a low appraisal, a low rent schedule, or a changed loan request can move the price without any breach by the lender.
- Ask for a lock extension before the lock expires. An expired lock is re-priced, not extended.
- Keep the financing contingency and the seller’s closing date aligned with the lock, so one slip does not become three.
Key Terms Defined
Lock: A lender’s written promise to hold certain pricing for a set period while the loan is processed, as long as the file matches the assumptions it was priced on.
Term sheet: A summary of the proposed loan, including program, leverage, and structure, that usually states it is not a commitment.
Lock confirmation: The document that shows what was locked, when it started, when it ends, and what voids it.
Commitment: A lender’s conditional agreement to fund once listed conditions are cleared.
Re-lock: A new lock at current market pricing after the first one has expired or been voided.
Float-down: A purchased option that lets the borrower take lower pricing once during the lock period.
Financing contingency: A clause in the purchase contract that lets the buyer exit, usually with the deposit returned, if financing fails on stated terms.
DSCR: Monthly rent divided by the monthly PITIA (principal, interest, taxes, insurance, and any association dues).
LTV: The loan amount divided by the lower of purchase price or appraised value.

What Does a Lock Actually Bind?
A lock binds the lender to specific pricing for a set period. It does not freeze the loan itself. If the facts the lender priced change, the lender can reprice.
Across the wholesale network, the lenders that lock early at application and the lenders that only firm up pricing once the file is clear to close behave very differently. A lock that only becomes firm at clear-to-close gives no protection through appraisal and underwriting, which is where most changes happen. Ask which kind you have before you rely on it.
| Usually covered by the lock | Usually not covered |
|---|---|
| Pricing, as written on the confirmation | Third-party costs like appraisal and title |
| Program and structure named in the document | Pricing if the loan amount changes |
| Lock period stated on the confirmation | Pricing if value or rent comes in different |
| Credits or adjustments written into the lock | Anything the confirmation does not mention |
The right column is where files get hurt. Most surprises come from assumptions that were never written down.
Which Document Holds the Lender to Anything?
Only the written lock confirmation and the commitment hold a lender to terms. A quote or term sheet is a starting point and can usually be changed.
| Document | What it is | Does it bind? |
|---|---|---|
| Quote | Verbal or emailed estimate | No |
| Term sheet | Proposed structure | Usually not |
| Lock confirmation | Dated pricing hold | Yes, within its conditions |
| Commitment | Conditional approval | Yes, once conditions clear |
On a purchase through a broker, the wholesale lender holds the lock and the broker relays it. That puts a duty on the broker to obtain the lender’s own confirmation, not a summary of it. Ask for the lender’s document itself.
The Federal Reserve Board describes a lock-in as a lender’s promise to hold certain pricing for a specified period while an application is processed. The CFPB adds that a lock holds only if you close within the stated time frame and the application does not change. It names a changed loan amount, credit score, down payment, or an appraisal that comes in different from expected as examples.
DSCR loans are business-purpose investor loans, so the consumer mortgage disclosure forms and their tolerance rules do not govern them. Treat those consumer sources as a model of good practice, not as a protection you can invoke. The lock agreement itself is the whole protection, which makes its wording matter more.
The Lock Confirmation Audit
Read the confirmation line by line before you rely on it. Each item below is a gap that has caused a file to reprice.
1. Dates. Check the lock start and the expiry date. Confirm the expiry falls after the contract’s closing date with a cushion.
2. Loan amount and leverage. The LTV tier the price assumes should be stated. On a purchase of an investment property, most files in the network land at 75% to 80% LTV, so a tier that sits on a boundary deserves a second look.
3. Coverage tier. The DSCR level assumed should be written down. A rent schedule that lands in a different tier can change the price.
4. Credit assumption. Confirm the score used. Most programs want around 660, a 620 floor exists in parts of the network, and 700 or higher opens the strongest leverage tiers.
5. Pricing adjustments and credits. Everything that adjusts the price should be itemized, not summarized.
6. Prepayment structure. Check it against the final documents. It is a term that can drift between the quote and the note.
7. Conditions that void the lock. The document should state what ends it and what happens if the loan does not close inside the lock period.
8. Extension and re-lock policy. Ask how an extension is priced and whether a re-lock uses current pricing or the better of the two.
9. Who holds the lock. In a broker file, confirm the wholesale lender’s name sits on the confirmation, so the hold is not just a promise from the intermediary.
Matching the Lock to the Purchase Contract
The contract’s closing date is the hard deadline. A lock that ends before it forces a choice between paying for an extension, re-locking at market, or asking the seller for more time.
Three clocks run at once on a purchase: the lock, the financing contingency, and the closing date. Mismatches between them are where investors lose money. Set them in this order:
| Contract item | What to align |
|---|---|
| Closing date | Lock expires after it, with margin |
| Financing contingency | Runs past the appraisal and rent schedule |
| Appraisal contingency | Lets you act on a low value |
| Seller extension right | Pre-agreed if lender work slips |
Without a financing contingency, a lock failure can become an earnest-money problem. With one, it becomes a negotiation. Build in the contingency before you sign, because it is hard to add afterward.
Decide up front who pays for a delay. If the seller causes it, an extension fee is often negotiable as a seller cost, and the request works best when raised as soon as the delay looks likely, not after the fee is charged. Lender-caused delay may also justify asking the lender to absorb the cost.

Which Changes Are Legitimate and Which Are Not?
A lender may reprice for a changed fact. It should not reprice because pricing moved in the market while your lock was active. The test is whether something in the file changed from what the lock assumed.
| Trigger | Reasonable? |
|---|---|
| Appraised value below contract price | Yes, LTV changes |
| Rent schedule below assumed rent | Yes, coverage tier changes |
| Loan amount or program changed by you | Yes |
| Credit score drops below the tier | Yes |
| Property flagged as an ineligible type | Yes, the loan may not be offered |
| Market pricing moved, file unchanged | No, ask for the reason in writing |
| Lender-side delay past lock expiry | Ask for support and a lender-paid extension |
On property type, the network does not offer DSCR loans on manufactured homes, log homes, or barndominiums. If an appraisal reclassifies the property that way, the issue is eligibility, not price.
Leverage and coverage tiers matter here because they sit under the price. A larger down payment lowers the monthly obligation and can lift the DSCR, but it does not erase leverage caps, credit floors, reserve rules, or property eligibility. Most programs also wait for 1.00 coverage to qualify on standard terms, though a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
If the Lender Moves the Terms
Respond in writing and in order. Each step asks for the reason before it asks for anything else.
1. Request the reason in writing. Ask which assumption changed and for the document that shows it, such as the appraisal or rent schedule.
2. Compare to the confirmation. Check the stated assumption against what the lock says. If the change is outside the listed triggers, say so.
3. Escalate to the loan officer, then operations or management. Keep the thread in one email chain with dates.
4. Bring in the broker or channel partner. A broker with several lenders can re-run the file elsewhere, and that option often moves the conversation.
5. Price the alternatives. Compare the re-priced loan, a different lender, and a renegotiated contract on the same assumptions.
A short request works better than a long one. State the lock date, the term that changed, and the document you need. The lender can then answer with facts.
If the Lock Is About to Expire
Ask for an extension before the expiry date. After it, the lender re-locks at current market pricing, and some use worst-case pricing, meaning the higher of the old or new level. That is a one-way risk, as Effective Agents notes in describing the extend-or-re-lock choice.
| Option | Tradeoff |
|---|---|
| Extend | Costs a fee, keeps existing pricing |
| Re-lock | Current pricing applies |
| Float-down | Must be bought up front |
| Switch lenders | Resets the file and may reset the appraisal |
A float-down and an extension are different tools. ConsumerAffairs explains that a float-down lets you lower your pricing once during the lock period, but only if you bought the option at the start. An extension only keeps the existing lock alive. Extension fees are typically a one-time cost that does not change the locked pricing.
New construction and complex files often need longer locks because timelines slip. Ask for the longer lock at the start rather than extending repeatedly.
Worked Example: Short Appraisal, Lower Coverage
Picture an investor with a signed contract on a duplex, financed as a purchase at 75% LTV. The lock assumes coverage of about 1.15x and a value equal to the contract price. These numbers are hypothetical, built to show the mechanics. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
The appraisal returns below the contract price, and the rent schedule is lower than the investor assumed. Two things happen. LTV is measured on the lower value, so the loan now sits at higher leverage than priced. Coverage drops toward 1.04x, still above 1.00 but in a lower tier. The lender reprices. That is a legitimate trigger, not a breach.
The investor then has four paths:
- Ask for appraisal reconsideration with recent comparable sales and condition adjustments.
- Renegotiate the contract price using the appraisal contingency.
- Bring more cash to bring leverage back to the priced tier.
- Walk away under the financing contingency, with the deposit protected.
The lock does not pick among these. The written assumptions let you see which path the lender’s change forces and which it does not. For packages of several properties, the issue multiplies, which Lendmire covers in its note on how a portfolio DSCR lender handles a package under contract.
One more point on coverage. Clearing 1.00 is not the same as positive cash flow. DSCR compares rent to PITIA only, and repairs, vacancy, management, utilities, and capex sit outside it.
Pre-Contract Checklist
Run these before you sign or waive a contingency.
- Ask the lender when the lock can start, not just what it costs.
- Get the lock confirmation template in advance.
- Confirm the financing contingency runs past the appraisal and rent schedule.
- Set a closing date that leaves room for a short extension.
- Agree with the seller on an extension right.
- Keep credit and deposits stable while the file is open.
- Read the complete DSCR loans guide for how coverage, leverage, and reserves interact, so no assumption on the confirmation surprises you.
Reserves matter to the file as well. They vary by lender, leverage, loan size, and transaction type, commonly around 6 months of PITIA, and loans above $1,500,000 typically step up to about 9 months. A reserves change late in the file is a documented trigger, so verify the figure at the start.
Frequently Asked Questions
Is a verbal lock from a loan officer binding?
No. Only a written lock confirmation or commitment holds a lender to terms. If the lock is not in writing, treat it as a quote and ask for the document before the contract’s financing contingency expires.
Does a DSCR lock cover the appraisal and rent schedule?
No. It covers pricing against stated assumptions, and a different appraised value or rent can legitimately reprice the loan. That is why the confirmation should state the LTV and coverage tiers it assumed.
Who pays if the lock expires because of a delay?
It depends on who caused the delay. A seller-caused delay can often be negotiated so the seller pays or contributes, and a lender-caused delay may justify asking the lender to absorb the cost. Raise it before the fee is charged.
Can I switch lenders if the terms change?
Yes, but it resets part of the file and may require a new appraisal. Weigh that against the cost of the re-priced loan. A broker working with several lenders can re-run the file on the same assumptions to make the comparison.
What if my deal has no financing contingency?
A lock failure becomes an earnest-money risk. Add a contingency before you sign when you can. If you cannot, set the lock length with extra cushion and agree on a seller extension right.
