Qualification Audit

Watch your application assemble itself.

Scroll through each qualification factor. Every green tick is one less thing standing between your family and a decision in principle.

01

Combined Income Verified

Affordability

Multiple income streams — PAYE, self-employed, rental, benefits — assessed together.

Up to 4 applicants. We use the top 2 earners for primary affordability, with others strengthening the file.

02

Credit Profile Compatibility

Credit

Mismatched scores handled. One strong file can offset gaps in another.

Some lenders now average credit scores across applicants. We route you to the right one.

03

Deposit Structure Confirmed

Deposit

Pooled savings, gifted deposits, equity release, and family contribution schemes accepted.

Joint applicants average a 36% larger deposit — unlocking sub-5% LTV rates unavailable to solo buyers.

04

Guarantor Eligibility Assessed

Guarantor

Parents, siblings, or close relatives added as Joint Borrower Sole Proprietor (JBSP).

The supporting party appears on the mortgage but not the deeds — preserving first-time buyer relief.

05

Property Type Approved

Property

Houses, flats, new-builds, and Help to Buy equity loan properties all considered.

We match your property type and purchase intent to lenders whose criteria fit your structure.

Who We Help

Every family structure has a mortgage route.

We've seen every combination. Here's how real families unlocked more than they thought possible.

"We'd been turned down by two high-street banks because of my self-employment gaps. Underwrite found a lender who used my last two years of accounts plus my husband's salary and got us £40,000 more than we expected."

"My parents are in their 60s and I was worried their age would restrict the mortgage term. Underwrite found us a lender with a 75-year repayment age limit and structured a 20-year term that worked for everyone."
