Most people under-estimate two things:
1. How important it is to do a proper inspection of the house and property.
...
You should view a property at least 3 times and take lots of photos. On your last visit, take a friend or family member. Look out for problems, and make a list of them!
Yes, this, exactly. Visit at different times of the day.
At least once while property hunting, it's worth paying a
really good inspector to view the property with you. This exercise will cost, but can be instructive.
Ask around for referrals, from banks, conveyancers and estate agents. Choose someone who has been doing it for years, and who is preferably not coming from the angle of a banker or an insurer, but rather
a master builder or a structural engineer . Agree in advance what this person will and won't provide, and don't go with anyone whose inspection will last less than an hour, better longer.
Arrange a time with the seller, and warn them that your inspector is going to go through their house thoroughly, and would like to look at the plans. If the owner doesn't have plans, get their signed permission (with a copy of their ID) to ask at the municipality if there are any, at all. Try to have these before the date with the inspector.
Take along a friend whose job it is to fully participate in the inspection, asking questions, just as you should do, and both of you with a clip-board to jot down his wisdom or, if everyone is in agreement, record everything. Take photos. Follow the inspector everywhere. Move around in the room if he blocks your view while working, so you can see what he is seeing or touching.
He (or you) should
switch on and off, open and shut, everything that can be steered: lights, run the water at every possible spot and check the entire pipe and tap for leaks, flush toilet, windows, doors, cupboards, locks, stove, oven, fans, air-conditioner, heaters, pool pump, creeply crawly, electric fencing, gates, remote, locks, beams. Check all the outbuildings including garage, lapa, shed, wendy-house, cottage, etc. with just as much precision. Ask him to look inside the basement, if any, and in the attic or roof, and at the garden, including plants which may be problematic, drainage across and in the earth, drains, boundaries, built fences, retaining walls and the pool if any, and benches, playground, awnings and paving.
Whenever the inspector criticises something, ask how he knows that, e.g. "there's water seepage here" because of what?... the smell / white chrystal deposits on the bricks / mildew, etc., or e.g. "the gutters aren't working" because of what?... watermarks down the outside wall / smudgy markings on the inside ceiling / water erosion on a spot on the ground, etc. Learn from him.
When he is finished, sit with him while and you and your friend ask him to name the worst aspects, and to give a rough estimate of what it would involve to repair or restore those, in money, time, and effort, and also what else would need to be done about this issue, before and afterwards, etc. Ask him for the worst case scenario, and whether he can see reasons why he himself would not buy. If there's a major baddie, obviously you'll probably walk away, but don't stop there: having noted that baddie, bracket it out so that you can ask about each room, inside and out. Include core functionality of things that are already wrong or likely to cause problems right away, or later, and also less essential, more aesthetic aspects. Even if the house is basically okay, ask him for the general (or if he will a detailed) cost of what he thinks one would need to invest immediately, or within the first year or two.
After having done that kind of inspection with an expert, I found that I could see the property ads, and view further properties, quite differently.
