Had an agreement in principle, then got declined?

Why it happens, even though you were told yes

An agreement in principle is a soft look. Most lenders run it on a light credit search and the figures you typed in yourself, in a few seconds, with nobody reading anything. It tells you the shape of what might be possible. It is not an offer and it is not a decision.

The full application is where a person and a much heavier system look properly. Payslips get read. Bank statements get read. The credit file is read properly rather than run through a quick automated check. And that is where the thing that was invisible at the first stage turns up.

Usually it is one of five things: something on the credit file that the automated check did not weigh, or that sat with an agency it did not look at, income that is real but does not count the way you assumed, spending on the bank statements that changes the affordability sum, a problem with the property rather than with you, or paperwork that does not match what was keyed in at the start.

How much does an agreement in principle actually guarantee?

Very little, and that is not a criticism of it — guaranteeing things is not what it is for. It exists so an estate agent will take your offer seriously and so you know roughly what size of loan is in range. It is built on figures you typed in yourself and a light check that nobody reads.

In my experience most of them do go on to become offers. That is the honest shape of it, and it is why being stopped at the next stage feels so much like a betrayal — it works often enough that nobody plans for the alternative.

What happens after it is roughly this: the full application goes in, documents are supplied, a person reads them, the property is valued, and if everything agrees with everything else, a formal offer is issued. The wait between those steps is where most of the anxiety lives.

On that: silence during the checking stage is usually a queue rather than a problem. Cases sit waiting for someone to pick them up far more often than they sit waiting for bad news to be delivered. If a lender wants something it will ask, and if it has decided against you it will say so. The absence of contact is rarely the signal people take it for — though if it has genuinely dragged on, asking your broker to chase costs nothing and settles it either way.

What not to do this week

• Do not fire off another application immediately. The temptation is enormous, particularly with a chain waiting. Another full application means another hard footprint, and a cluster of them makes the next lender more cautious, not less.
• Do not assume every lender will say the same. They very often will not. The lender that declined you has one set of rules; it is not the market.
• Do not hide the decline from whoever helps you next. It comes out anyway, and it is far easier to explain up front than to be discovered.

What I would do instead

Find out what actually triggered it — the lender will sometimes say, and your credit file usually fills in the rest. Then work out which lenders treat that specific thing differently, and approach one of them properly, with the explanation attached rather than left to be discovered. If there is a deadline, tell me at the start; it changes which lenders are realistic, because some are considerably quicker than others.
