Three things matter more than the cosmetic to-do list, and most new owners skip all of them. - Get your estate planning in order. Putting the property into a trust, or at minimum setting up a will, keeps the home out of probate and makes clear where it goes. Plenty of financially comfortable people never do this. Work with a trust attorney rather than fully DIY-ing it, and cover medical directives in the same conversation. We're not attorneys, so treat this as a nudge to see one, not legal advice. - Watch your mail for scams. Official-looking letters demanding payment for a "home warranty" or a copy of your deed show up fast after closing. It's junk. You never need to pay for a copy of your own deed. - Shop your insurance instead of letting it auto-renew. Premiums creep, and because homeowners insurance often rides inside your mortgage payment through escrow, a big jump can slide by unnoticed. Re-shop homeowners and auto coverage every year or so. One state note: in California, Proposition 13 caps the annual increase in your assessed value at 2%, gentler than states that reassess toward market value more aggressively and can hand owners larger jumps. Wherever you are, confirm how your county handles reassessment so the tax line doesn't surprise you later.
