The Mortgage Maze: Five Months to the Finish Line

Tomorrow our solicitor will draw down the funds, and at last — after five long months — we’ll complete on the barn. It’s been a marathon, not a sprint. For anyone curious about how a self-build mortgage actually plays out, here’s the story so far, and why just getting to this point feels like a huge win.

1. Getting Stage Payments in Advance

Most lenders release funds in arrears, after work is done. That doesn’t work when you need to pay trades as they go. From day one, I wanted stage payments in advance, and that requirement alone narrowed the field of lenders drastically. Tomorrow, we’ll finally see the first stage land in the account.

2. The “Conversion” Label

Although our barn is a solid steel RSJ frame, owing to being a Class Q, lenders only saw the word “conversion.” That put us in the same bucket as crumbling old barns with unpredictable surprises. Fair enough from their perspective, but frustrating when our structure is actually sound. It added months of explaining and reassurance.

3. Acting as Our Own Contractor

We chose not to bring in a general builder. Instead, I’m the principal contractor, hiring and managing every trade myself, a true self builder. It’s the most cost-effective approach — avoiding the 30%+ premium a builder would charge — but it gave the lenders pause. They much prefer one accountable general builder to tick their boxes.

4. The Warranty Problem

No lender wants to proceed without a warranty or architect’s certificate. Finding a warranty provider for a self-managed conversion was near impossible, and the one quote we did get was double what it should have been. The solution came through our engineer, who was willing to issue an architect’s certificate under his professional insurance, inspecting stages as we go. It satisfied the lender and avoided a big upfront bill. Later, when we have building regs drawings, I’ll still place a full 10-year warranty, but for now, this got us across the line.

The Quirky Logic of Lenders

Getting the paperwork right wasn’t just about big hurdles; it was also about navigating some head-scratching quirks:

• Spare cash didn’t count: Even with bank statements showing healthy reserves, the lender only considered the deposit and loan. At one point they told me I was £4,000 short. I had to literally point them to another account to prove we weren’t about to go bust.
• Monthly insurance flagged as “too much”: Their affordability calculator said my outgoings were too high because of things like dog insurance and car cover. The fix? Pay them annually in advance. Suddenly, I was “affordable.”
• Proof of employment, again and again: Because the process dragged on for five months, I had to repeatedly confirm I still had a job. Each time it felt like they half expected me to have quit between emails.
• Last-minute rate change: Two days before completion, the interest rate dropped. My broker warned it couldn’t be processed in time. The building society said otherwise — if everyone hustled. Cue frantic calls between broker, BuildLoan, and solicitor. By the next morning, we had the lower rate confirmed and avoided late-completion penalties.

Looking Back (and Ahead)

It’s taken five months, a stack of paperwork, and no shortage of persistence — but tomorrow we complete. That means the first stage payment, the keys, and the real start of turning this barn into a home.

For now, we’re celebrating reaching the finish line on the mortgage. The build itself is another story — and one we finally get to start writing.
