Software for the building inspection, from roof to crawl space

In a building inspection, you go through the whole home as the building inspector, from roof to crawl space. You record what is in order, which defects there are and roughly what repairs will cost.

A buyer has the home inspected before the purchase: that is called an aankoopkeuring (pre-purchase inspection). A seller can also have the home inspected. And sometimes the lender asks for a report for a mortgage with NHG (Nationale Hypotheek Garantie, the Dutch National Mortgage Guarantee).

For a mortgage with NHG, a building inspection report is not always needed. According to NHG, it is required if the valuation report shows one of these three things:

• Overdue maintenance needing prompt repair, costing more than 10% of the market value
• Further building investigation is needed
• The structural condition of the home is poor

Keursnel works with a fixed template of 42 chapters and over 4,800 answers. The home profile determines which chapters and rows belong to this home.

Every answer gives a text, a rating, an amount and a timeframe. The rating is good, adequate, fair, poor, further investigation or not assessed.

If the home has two bathrooms or three dormers, each one gets its own answers and costs. This works for 14 building elements, such as the dormer, the bathroom and the boiler.

Search for a word such as “panhaken” (roof tile hooks). With one tap, you choose the answer and jump to the item. With Rest in orde (“mark the rest OK”) you set everything still open in a chapter to “in orde” (in order) in one go. Keursnel first asks whether you were able to look at everything.

A few of the 42 chapters:

• Roof structure and framing, roofs and gutters
• Facades, external window frames and glazing
• Services: electricity, water, gas and heating
• Ventilation and fire safety
• Crawl space, foundations and rising damp
• Materials suspected of containing asbestos

The report grows as you inspect. At the top is Ons beeld van de woning (“our view of the home”). It is a running narrative: the overall picture, what takes priority and what it costs.

Keursnel writes that narrative using fixed rules, without AI. You can replace any paragraph with your own text.

Then come In het kort (“in short”) and Eerst doen (“do first”). Eerst doen puts the points in a fixed order: first safety, then consequential damage, then what must be done within 1 year.

The cost overview shows the costs per chapter and per timeframe: within 1 year, within 5 years and improvement costs. The amounts come from a table of 1,176 rates, or from your firm's own prices. If an amount is not right for this home, change it and give a reason.

The report shows the amounts as indicative, stating whether they include or exclude VAT. For a paid inspection, the report can come fully in your own house style, with a choice of 20 designs.

These are the parts of the report:

• Cover page, contents and home details
• Ons beeld van de woning, In het kort and Eerst doen
• Overview and chapters, with findings and photos
• Cost overview per chapter and per timeframe
• Not assessed and not applicable
• NHG annex and disclaimers

When a building firm makes a report for NHG, it must use NHG's Model bouwkundig rapport (model building inspection report). Keursnel makes an NHG annex with every full report, even on the free plan.

NHG does not approve software, and that includes Keursnel. The lender checks whether the report meets the requirements. Some of those requirements lie with your firm, not with the software. Your firm must be registered with the KvK (the Dutch Chamber of Commerce) and be independent. And the report must be no more than 12 months old.

The annex contains the codes, the action per line item, the improvement costs and the remarks. For an apartment, you fill in the k.v. (kostenverdeling, the cost split), and Keursnel calculates the home's share.

Next to the answers, you see which NHG code the costs count under. You can change or remove the code, with a reason that goes into the report.

The annex matches the cost overview. Improvement costs and line items without an NHG code are listed separately. That way, you can see how the two totals reconcile.

The B codes are in a table per storey, and the summary sheet (verzamelstaat) has the lines of the model. NHG's programme of requirements and recommendations is at the end.

Further down this page, you can see what the NHG model asks for each requirement and how Keursnel fills it in.

You start for free. You can deliver 3 reports a month per organisation, with a watermark and 1 photo per topic. Even then, every full report gets an NHG annex.

If you inspect more, a paid inspection costs 1 credit. A single credit costs €25 and does not expire. With a subscription, you pay from €7.50 per inspection. All prices exclude VAT.

A paid inspection has no watermark. The report shows 4 photos per topic and can use your own house style.

For comparison: according to its own pricing page, Keursoft (mijnwoning.nl) charges €32.50 per building inspection, excl. VAT (checked in November 2026). If you try Keursoft for free, you get €50 credit.

Keursoft is software for building inspectors. You log in via mijnwoning.nl. Keursoft also mentions an NHG annex in the report, and says it meets NHG's Model bouwkundig rapport.

According to its site, Keursoft works with an internet connection, and it does not mention an offline mode. You pay per inspection, without a subscription.

With a paid inspection, the Keursnel report comes fully in your house style, with a choice of 20 designs. Your client can also read it as an online report, with the tabs Overzicht (“overview”), Kosten (“costs”), Rapportage (“report”), NHG and Keuring (“inspection”).

Below, you can see how Keursnel handles points that inspectors often compare. What Keursoft's site says about the same points is in the table further down.

• Also works without internet, encrypted on your device
