Is it really important to check a house before buying it for things like electricity, gas (if there is any), plumbing, and all that? Sorry, of course, I don't buy real estate every week, so I have a ton of questions.
For sure. It's important to do this both for safety reasons and to lower the cost of the house if any issues are found that aren't critical enough to cancel the purchase. Generally, your realtor should be the one to tell you this. Before I bought my house, I consulted with Ben's Plumbing about the condition of the plumbing and sewage https://bens.plumbing/services/plumbing/emergency/. They're great specialists, they come for emergency calls within 1-2 hours, and for regular requests, they're still pretty quick. You can even just consult with them.
