Got a Mortgage Offer? 5 Mistakes That Can Cost You Your Home

Got a Mortgage Offer? 5 Mistakes That Can Cost You Your Home

Just Got Your Mortgage Offer? Read This Before You Relax


Receiving a mortgage offer is a huge milestone. It feels like the hard part is over.

In reality, you are not finished yet.

Every year, borrowers in Ireland lose their mortgage approval after receiving an offer. Not because of market changes or lender policy shifts, but because of avoidable actions taken between offer and drawdown.

Until the day your loan is drawn down and the keys are in your hand, your lender can still reassess your application.

Here are the five most common mistakes we see that put mortgage offers at risk, and how to avoid them.

1. Taking Out New Credit After Your Mortgage Offer


This is the biggest mistake, and the most common.

Once your mortgage offer is issued, you should not take out any new credit of any kind. This includes:

  • Car finance or personal loans

  • Furniture or appliance finance

  • Buy now pay later services

  • Credit card balance increases

Lenders can recheck your credit report and bank statements right up to drawdown. New borrowing can trigger a full reassessment of your affordability.

In some cases, the offer is withdrawn entirely.

Rule of thumb: if it creates a monthly repayment, do not do it.

2. Missing or Being Late on Any Payments


At this stage, your financial conduct needs to be spotless.

One missed or late payment on a credit card, loan, overdraft or utility bill can raise red flags with the lender. Even if the amount is small, it can be enough to delay or derail the drawdown.

Direct debits should be monitored closely. If anything fails, resolve it immediately and keep records.

Consistency matters more now than at any other point in the process.

3. Stopping or Reducing Your Savings


Many buyers assume that once approval is granted, savings no longer matter. That is not the case.

Lenders assess repayment capacity using your bank statements, often over a six-month period. If updated statements are requested before drawdown, they expect to see:

  • Ongoing savings

  • Stable spending patterns

  • Sensible money management

A sudden stop in saving can prompt further questions, delays or conditions.

Keep saving right through to drawdown, even if the amount is modest.

4. Changing Jobs Without Advice


Changing jobs is considered a material change in circumstances.

Your mortgage offer is based on your current role, income, contract type and probation status. Accepting a new job, even with a higher salary, can invalidate the approval.

This is particularly important if:

  • You are moving during probation

  • You are switching employment type

  • You are self-employed or contracting

If a new opportunity arises, speak to your broker first. In many cases it can be managed, but timing and structure are critical.

5. Delays in Meeting Loan Conditions


Mortgage offers often come with specific conditions that must be met before drawdown. These can include:

  • Proof of deposit

  • Gift letters

  • Updated payslips or accounts

  • Property or insurance documents

Delays in supplying paperwork, slow responses or incomplete documents can cause serious problems, especially when closing dates are tight.

In worst-case scenarios, the sale can fall through.

Organisation and responsiveness matter just as much as affordability at this stage.

Getting the Offer Is Only Half the Job


A mortgage offer is not a guarantee. It is a conditional approval that must be protected.

The period between offer and drawdown is where many buyers unknowingly undo months of careful preparation.

If you are unsure whether a decision could affect your mortgage, ask first. A short conversation can prevent a costly mistake.
