Estimating Building Expenses: What Tools Or Sites Do You Trust?
Yeah, I totally get what you mean about those “surprise” costs. I’m building my first house right now, and honestly, half the time I feel like I’m just waiting for the next random fee to pop up. RSMeans and similar sites are helpful, but I swear, every time I think I’ve got the numbers dialed in, something local throws a wrench in the works. My city apparently charges a separate fee for driveway aprons—who knew that was even a thing?
I’ve tried a bunch of online calculators, but most of them just give you a very rough average. Useful for a starting point, but I learned the hard way that you can’t trust them for the weird line items. I started keeping a spreadsheet of every weird expense that’s come up. It’s not fancy, but at least now I can look back and remember, “Oh yeah, the sidewalk permit from last year—don’t forget that.”
I’ve also found that just talking to neighbors or people who’ve built recently is way more useful than most websites. Folks love to share their horror stories, and you pick up on all the little “gotchas” that way. Contractors are helpful too, though sometimes they seem just as surprised by the fees as I am.
Sometimes I wonder if there’s a secret manual everyone else got when they moved here... but until I find it, it’s a mix of spreadsheets, crossed fingers, and a lot of double-checking. If nothing else, at least I’ll have a good list of “surprise” costs to warn the next person.
