Husband and I wouldn't have bought a house when we did. We were in our mid-20s, newlyweds, and under so much pressure from everyone in our lives—seriously, not one person suggested that maybe we should just enjoy being married for a couple of years to see what worked for us. Everyone told us that it would be the best investment we would ever make, we might as well throw our money away if we were renting, etc., all the standard tropes from people we loved and trusted. Instead, the house has tied us down in ways that we didn't foresee and has limited many of our decisions, especially as its value plummeted to 20% of what we initially paid when the market crashed (5 years after we bought it) and we couldn't sell it. We're finally at the point where it would sell for more than we owe.
We're also late coming to frugality/mustachianism so we would have been subject to consequences of financial laziness regardless, but the consequences were much bigger with a house that required a planned full bathroom reconstruction two years ago (water damage from a poor remodel by the previous owners) that wiped out our home repair savings, followed that winter by the unexpected deaths of our furnace and hot water heater (which were replaced on credit because of bathroom; furnace is finally paid off and hot water heater is close). In fact, avoiding being caught out like that again was our initial incentive for high frugality. We're going to need a new roof within the next 12 months, and I want to pay cash.
If we'd skipped the newlywed house, I don't know if we would have bought when the market bottomed out, or if we'd have kept renting. Sometimes we really, really miss having a landlord. We also wish we could invest the roof money and maybe use a little of it to take a trip.
