It's a good idea to get the property checked by someone who can identify significant defects, future or urgent maintenance issues and problems caused by gradual deterioration. We recommend using a qualified and insured building inspector to do this work.
If you get a DIY guru friend in to have a look, ask them to look for structural problems, any evidence that the property is a leaky building, issues caused by deferred maintenance (such as weatherboards rotting due to peeling paint) and areas where there is damp or mould.
Simple things like aged electrical or water supply fixtures may also create headaches later on. Factor in costs for fixing any problems that may be significantly more involved to manage than town repairs and maintenance, as well as plan for long-term upkeep.
You also need to be hard-headed about the risk of natural hazards such as tsunamis or coastal erosion.
Earlier this year, a report commissioned by the Deep South National Science Challenge pointed out that nearly 44,000 homes in New Zealand are less than 1.5m above the average spring high-tide mark.
With rising sea levels and increasing likelihood of storm surges and king tides predicted, many of these properties are at risk of frequent inundation.
Insurers are nervy about this, with some companies raising premiums or excesses for properties that have been identified as high-risk, or putting restrictions on what they will cover. It can be difficult to get finance approved if a property cannot be insured.
If you get through all those steps and the property still looks like a good bet, think about the long-term.
Are you thinking about using it to earn an income, such as renting it out or putting it on Airbnb or a similar platform? Be aware that some councils are tightening up restrictions on homeowners doing this.
Think about security as well.
Finally, if the property you are keen on is being sold privately, you may have fewer protections under the Consumer Guarantees Act and the Fair Trading Act if things go wrong.
While no one enters into a sale thinking that problems are going to arise, issues can often crop up.
