LIM Reports, Builders Reports, and Valuations: What the Bank Actually Requires

A quick heads-up: The information in this article is designed as a general educational guide only and does not constitute personalised financial, tax, or legal advice.

When you walk through an open home, it is natural to look at the property through an emotional lens—picturing how your furniture will fit, checking the afternoon sun, and imagining life in the neighbourhoodWhen a bank looks at that exact same property, they are looking through a very different lens: risk.

The bank is putting up the vast majority of the purchase money, so they want complete certainty that the home is structurally sound, legally compliant, and genuinely worth what you have agreed to pay. To satisfy their credit teams, lenders rely on three core due diligence documents: LIM reports, building inspections, and Registered Valuations.

Here is a practical look at how the bank views each one, how they connect behind the scenes, and when they become a formal condition of your mortgage approval.

1. The LIM report and the insurance chain reaction

A Land Information Memorandum (LIM) is a comprehensive record of the property and its surrounding land held by the local city or district council.

A common surprise for buyers is that banks rarely ask to read the LIM themselves on a standard residential purchase. Instead, the LIM acts as the quiet gatekeeper for your property insurance.

Banks have an absolute rule: no insurance, no mortgage. To draw down your loan on settlement day, the lender requires a Certificate of Currency showing full replacement cover with the bank noted as an interested party, free of major exclusions.

This is where the chain reaction happens:

• Your solicitor reviews the LIM and checks for council hazard notices, such as 1-in-100-year flood plains, coastal erosion, landslip history, or unconsented building works.
• You are legally required to disclose these known risks when applying for house insurance.
• If the insurer hesitates and adds a restrictive clause (for example: 'We will insure the home, but exclude overland flood damage'), the bank's security is compromised.

In most cases, it is not the council report that stops your lending directly. It is the effect the LIM has on your insurance policy that prompts the bank to reconsider the loan.

2. When does a bank insist on a building report?

A professional building inspection provides an independent visual check of the home's condition, weathertightness, and structural integrity.

While getting a building inspection is always sensible due diligence for your own peace of mind, a bank will generally make a written report from an accredited inspector a mandatory loan condition in three specific situations:

• It is written into your Sale and Purchase Agreement: If your offer includes a building condition, the bank's credit team will often adopt that requirement as their own. If you have flagged that you want the building checked before going unconditional, the bank will want to see that the report is satisfactory before confirming your finance.
• The valuer spots deferred maintenance: If a registered valuer visits the property and notes visible maintenance concerns—such as spongy flooring, an ageing roofline, or poor site drainage—they will flag 'deferred maintenance' in their report. The bank will then typically require a qualified inspector to investigate the true extent of the work required.
• The marketing sends up a flare: If the listing description uses phrasing like 'handyman's dream', 'renovator's delight', 'bring your toolbelt', or 'selling as is, where is', bank credit assessors will automatically flag the property as high-risk security and require an inspection before approving the lending.

3. Registered valuations and internal system triggers

A registered valuation is a formal, comprehensive market appraisal conducted by an independent valuer who physically inspects the property, compares recent local sales, and determines its current fair market value.

Banks typically make a valuation mandatory in scenarios such as:

• Purchasing with less than a 20% deposit (low-equity lending).
• Buying privately without a licensed real estate agent.
• Purchasing a property from a family member (a non-arms-length transaction).
• Funding a turnkey new build or major construction project.

The automated valuation trigger

There is another common scenario that catches buyers off guard: even if you have a full 20% deposit and buy through an agency, the bank might still ask for a valuation if their internal computer model cannot verify the price.

The strict ordering rule for valuations

If the bank requires a registered valuation, you cannot usually ring a local valuer and hire them directly (although a couple of banks still allow this).

Sorting your finance before paying for reports

Ordering a council LIM, hiring an accredited building inspector, and paying for a registered valuation can quickly add up to several thousand dollars per property.

Before spending that money on a house you might not end up buying, it is always wise to have your borrowing power verified first.

At Home Loan Factory, we can check how lenders view the specific property you are looking at, let you know which reports will likely be mandatory, and ensure any required valuations are ordered correctly through the approved banking portals.

Understanding Bank Requirements

How does a LIM report affect a mortgage application?

While a bank may not directly ask for a LIM report on a standard purchase, the LIM can highlight risks like flood zones or unconsented works. You must disclose these risks to your insurance company. If the insurer places special exclusions on your policy as a result, the bank may decline your mortgage, as they typically require standard, unconditional insurance cover.

When do NZ banks require a building report?

Banks will often require a building report if you have included it as a condition on your Sale & Purchase agreement, if the property is advertised as a "do-up" or "renovator's dream," or if a registered valuer flags visible deferred maintenance that needs further investigation.

Why do banks ask for a registered valuation if I have a 20% deposit?

Even with a 20% deposit, a bank may ask for a registered valuation if their internal automated systems flag the purchase price as being significantly higher or lower than their expected data suggests. They may also require one if you are buying privately or purchasing from a family member.

Can I order my own registered valuation for the bank?

Not usually. If a bank requires a registered valuation for a mortgage approval, you cannot hire a valuer directly. The valuation must be ordered through an approved, independent, centralised system (such as Valocity or CoreLogic), which assigns a valuer randomly to ensure complete neutrality.
