Assumptions: costs escalate at a combined 7.0% per year (tender price inflation + scope creep). The repair borrowing is modelled as a top-up loan at the same mortgage rate, repayable over the period until repairs are carried out. Indicative figures only — not a quotation or financial advice.

Property value · repaired vs unrepaired

Buildings that fall behind on repairs grow more slowly than well-maintained ones. This is the value gap, projected over your mortgage term.

Heritex lease-back option

An alternative to a traditional repair loan. You pay an affordable monthly amount; the principal is settled with a balloon payment at the end of the lease, when your property's value has grown.

Monthly affordability · loan vs lease

Both stacks include your existing mortgage. Compare what you'd pay each month if you funded repairs with a top-up loan, versus the Heritex lease-back.

Lifetime cost vs property value

What each option costs over the full mortgage term, set against the value of your home at the end of that term — repaired vs. left to decline.

Bars are scaled to the largest value across both groups. The lease model compounds interest on the original funding amount; monthly payments reduce the principal portion of the balloon, but interest accrues regardless.
