Why Mortgage Applications Get Rejected in Sidcup (Even After an Agreement in Principle)
One of the most frustrating experiences for buyers in Sidcup is having a mortgage application rejected after receiving an Agreement in Principle (AIP). Many people assume an AIP means the lender has already approved the mortgage, only to discover later that the full application tells a different story.
This article explains why mortgage applications can fail after an AIP, what lenders reassess at the full application stage, and how buyers in Sidcup can reduce the risk before committing to a property.
What an Agreement in Principle Actually Confirms
An Agreement in Principle is an early indication based on limited checks. It usually relies on the income and outgoings you declare and a preliminary credit check. It is not a mortgage offer and it is not a full affordability or underwriting decision.
Problems often arise once a lender moves from assumptions to verified evidence.
Affordability Often Changes After Full Review
In Sidcup, many buyers are surprised by how affordability changes once bank statements and payslips are reviewed properly. Lenders look closely at what is left after regular commitments and apply stress testing to ensure the mortgage remains affordable if interest rates rise.
Common issues include:
-
Car finance and PCP agreements reducing borrowing power
-
Credit card balances and minimum payments
-
Childcare, commuting, and household costs being fully assessed
-
Variable income being reduced or excluded
-
Stress testing at higher interest rates
Credit Behaviour Matters More Than Scores
A common misconception is that a good credit score guarantees approval. In reality, lenders focus on recent credit behaviour and patterns rather than just a headline number.
Issues that often cause concern include:
-
High utilisation across credit cards
-
Recent missed or late payments
-
New borrowing taken out after the AIP was issued
-
Regular overdraft usage
-
Multiple credit searches in a short period
Stability between the AIP and the full application is critical.
Property Issues Common in Sidcup
The property itself can also be the reason a mortgage application fails. In Sidcup, flats and converted properties often attract additional scrutiny from lenders.
Examples include:
-
Short lease lengths on flats
-
High service charges affecting affordability
-
Ground rent clauses some lenders dislike
-
Converted properties with limited documentation
-
Down-valuations where the lender values the property below the agreed price
Employment and Income Evidence Problems
Even when income appears sufficient, applications can fail if it does not meet a lender’s exact criteria once documents are reviewed.
Common problems include:
-
Probation periods or limited time in a new role
-
Self-employed income not aligning with tax returns
-
Bonuses or overtime lacking consistency
-
Multiple income streams not accepted by all lenders
-
Large unexplained credits in bank statements
How Buyers in Sidcup Can Reduce the Risk of Rejection
Most mortgage rejections are avoidable with the right preparation. The key is to remove surprises before the lender finds them.
Practical steps include:
-
Reviewing bank statements early
-
Reducing unnecessary credit commitments
-
Avoiding new credit after an AIP is issued
-
Preparing documents before applying
-
Checking lease details early when buying a flat
