Most first time buyers don’t fail because they’ve done something reckless.
They fail because they’ve done something normal — based on advice that no longer fits how mortgages are assessed in 2026.
We speak to first time buyers every week who earn decent incomes, have savings behind them, and still feel surprised when applications slow down, change, or don’t go the way they expected.
The same issues come up again and again. Not dramatic mistakes — just small assumptions that quietly cause problems later in the process.
Below are the most common ones we see.
The Mistakes That Catch Buyers Out
Starting viewings before understanding affordability
Assuming a good salary equals easy approval
Ignoring spending because there’s no debt
Relying on online calculators alone
Mortgage calculators provide estimates, not decisions. They don’t factor in lender-specific stress testing or future pressures.
Applying too quickly after improving credit
Quick improvements look good on paper, but lenders still prefer stability over time.
Case Studies
Case Study 1: Sophie – Norwich
Sophie had saved a 5% deposit and assumed her salary meant approval would be straightforward. What caused delays was her recent job move and probation period.
The income wasn’t the issue. Timing was. Once expectations were reset and the right lender chosen, her purchase went ahead without overstretching.
Case Study 2: James and Hannah – Stockport
James and Hannah had no debt and strong credit scores. What they hadn’t considered was how childcare costs starting later that year would be viewed.
By planning for this early, they avoided last-minute changes to their borrowing and chose a mortgage that still felt comfortable once costs increased.
Case Study 3: Aaron – Plymouth
Aaron relied heavily on online calculators and viewed properties at the top of his estimated budget. When lender affordability came in lower, he felt stuck.
After reassessing realistically, he secured a mortgage that allowed him to buy without constant financial pressure.
Why These Mistakes Matter More in 2026
First time buyers are now assessed using the same sustainability checks as homeowners.
Lenders are less interested in whether a mortgage works today and more concerned with how it holds up if circumstances change.
The earlier these factors are understood, the smoother the process tends to be.
