02The work happens

Underwrites

Reads every page — forms and narrative letters alike — checks each 1003 field against the documents, and recalculates what's wrong, showing its math.

→
03The gaps close

Conditions

Reviews AUS findings, writes its own conditions beyond them, and drafts the borrower requests that resolve each — then clears them as documents land.

→
04The package goes out

A submission-ready package: every figure justified and cited, every condition cleared, synced to your LOS for sign-off.

Shows its math

Every figure carries a line-by-line justification, a citation to the source page, and the standard forms ready for review.

Knows your rules

Your overlays, your past underwriting decisions, and the agency Selling Guides (FNMA, FHLMC, FHA, VA, USDA) — flagging the binding rule when they conflict.

Lives in your stack

AssetsPrior to approvalOpen

Gift letter is dated 12 days after the deposit it explains

The $18K posted Mar 2; the gift letter is signed Mar 14. Mort wrote the condition an underwriter would.

Satisfying document — required

Donor bank statement · Feb–MarAwaiting

Why Mort wrote it: the sourcing chain must show donor ability and date order (FNMA B3-4.3-04). A letter signed after the funds moved can't establish either on its own.

To: priya.n@gmail.com · Re: Two quick items on your loan

Hi Priya — two things will keep your approval on track:

1.

A Feb–Mar bank statement from your mom (the gift donor). Why: guidelines require showing the $18K left her account before it reached yours.

2.

Your November bank statement for the reserves check. Why: guidelines require 60 days of history through closing.

Appraisal came in at $695K — $25K under contract. What are Priya's options?

Mort

Three, and one is stronger than it looks. At $695K, LTV moves to 83.4% — triggering MI and a pricing hit of ~$310/mo.

FNMA B4-1.3A value dispute needs comps the appraiser missed — not a complaint.

YOUR OVERLAYRequires a desk review before any reconsideration of value.

YOUR HISTORYYour last 6 ROVs won value only when comps closed within 90 days — Mort found two in the appraisal's own grid.

Lead with the reconsideration of value using those two comps; fallbacks: renegotiate price, or borrower covers the $25K gap.

On the files that bite

Examples where Mort shines.

Undisclosed debits hiding in the bank statements

Scenario · 1003 + credit report show $550/mo in debts. AUS Approve/Eligible at 31.5% DTI. Will the file actually clear?

m

Reads every line of the bank statements against the 1003 + credit to surface child-support, IRS installment plans, and BNPL, then requests and reads each substantiating doc (decree, IRS installment agreement, account statement).

Title and appraisal, read against the file

Scenario · The title commitment lists a solar UCC filing and an HOA. The appraisal notes an unpermitted addition and comps that skip the subject's condition rating. None of it is on the 1003.

m

Reads Schedule B exceptions against the 1003 and credit report — flags the solar lien for subordination or payoff, adds the HOA dues to the housing ratio, and checks the appraisal's condition/comp logic against agency requirements before the underwriter ever opens it.

Large deposits, sourcing chain, integrity checks

Scenario · Earnest money landed outside the standard statement window. A gift letter is dated after the deposit. A wire came from an account the borrower never disclosed.

m

Reads each deposit against the GSE sourcing threshold, then reads the narrative behind it (gift letter, donor statement, transfer evidence, borrower LOE) and decides whether the chain holds: date ordering, donor-ability, undisclosed accounts. Each deposit lands a verdict before submission, not a generic condition.

Multi-entity self-employed, K-1 distributive share

Scenario · Schedule E shows ownership across three entities: an S-corp, an LP, and a sole-member LLC. Will the distributive share actually qualify?

m

Maps each entity and asks upfront for the missing K-1s, business returns, year-end balance sheet, and CPA liquidity letter. Reads the CPA letter itself: whether it explicitly attests to liquidity, business stability, and the borrower's continued access to distributions.
