Inflation is still hanging around even though it's dropped quite a bit over the past couple of years. The thing is, banks raise interest rates specifically to slow it down, so your dad's got a point there. In 2026 we're in a situation where mortgages are more expensive than they were recently, basically because banks charge more for the money they lend you. If you could get a mortgage at 3% before, right now you're looking at more like 4%, 4.5% or even higher depending on the bank and how much cash you've got for a down payment.
The rough part is that house prices haven't fallen at the same rate that interest rates have gone up, so you end up paying more in two ways: the house itself costs more, and on top of that you need to pay more in interest each month. It's a bad combination honestly. Some people say it's gonna get better in the coming months, others say it'll take longer, the thing is nobody really knows for sure. Central banks are watching how inflation goes but it's all pretty uncertain.
My advice, and take it with a grain of salt because I know about as much about economics as I do (which is not much, honestly, I'm more focused on whether new Elden Ring DLC is coming out haha), is that if you've got the resources and the need to buy now, you might as well do it. Waiting doesn't guarantee anything will drop, it could even go up more. The important thing is to look carefully at how much you can actually afford monthly without ending up broke.
