The Casaroo Home Buyer's Library

Plain-English, sourced explainers on both halves of a home. The bones: the wiring, plumbing, roof, and structure that quietly cost buyers the most and that listings never show. The appearance: the flooring, kitchens, baths, and trim you can see, priced room by room so 'dated' stops being a feeling and can inform your offer. Written by Casaroo to help you read a home before you fall for it. Education and triage, not a home inspection.

The ten second check

What else is typical in a house this age?

Type the year the house was built and I will tell you what else tends to be true at that age, what it costs, and what to ask. One number, ten seconds.

A guess is fine. 1965, or just the 60s.

Anything worrying you? Tap any that apply, or skip it.

Free. No account. Educational and impartial, not a home inspection.

The bones · what it costs after you move in 61 guides

Electrical

Old or failure-prone wiring and panels are among the most expensive, and hardest to insure, problems a buyer can inherit. Here's what to look for before you make an offer.

6 guides

Plumbing & Water

The pipes behind the walls decide whether you face a quiet repipe or a sudden flood, and some materials are now insurance and health issues. Know the material before you buy.

14 guides

Roofing

A roof is one of the largest predictable costs in a home, and its age shapes both your offer and your insurance. Learn to estimate the years left from the ground.

3 guides

Structure & Foundation

Most foundation cracks are ordinary shrinkage; a few are five-figure problems. The whole game is telling them apart before you remove your conditions.

6 guides

Exterior & Drainage

The cheapest fixes prevent the most expensive damage. How water moves around a house is the single biggest driver of wet basements and foundation trouble.

8 guides

Heating, Cooling & Chimney

Combustion appliances and chimneys are safety items first, cost items second, and they're high up and rarely photographed, exactly where listings hide problems.

6 guides

Insulation & Ventilation

Where warm, moist air ends up decides whether an attic stays dry or quietly rots. These are cheap fixes that prevent expensive, hidden damage.

5 guides

Interior & Health/Safety

Some hazards aren't a problem until you renovate. Knowing where they hide lets you plan, and budget, instead of being surprised mid-reno.

10 guides

Windows

Foggy glass and old sealed units are easy to miss and easy to negotiate, once you know to look between the panes for the date stamp. Here's what windows really cost.

The appearance · what it costs to make it yours 35 guides

Kitchen

The single largest cosmetic line item in most homes, and the one where the tiers differ by a factor of five. What a refresh, a reface and a full renovation actually cost, and how to tell which one a kitchen needs from the listing photos.

8 guides

Bathrooms

Small rooms, big bills. Bathrooms carry the highest labour cost per square foot in the house, and the price hinges almost entirely on one thing: whether the plumbing moves.

6 guides

Flooring

Flooring prices per square foot, which makes it one of the very few things in a listing you can actually put a number on from the photos. Here is what each material costs, how long it lasts, and when a floor problem is not a floor problem.

8 guides

Interior Finishes

Doors, trim, hardware, lighting and paint. Individually cheap, collectively a five-figure job, and the place a flip gives itself away: renovators touch these last and skip them first.

8 guides

Reading a Listing

The pattern-recognition cards. How to read a finish tier, spot a flip, see past the staging, date a home by its finishes, and tell the difference between cosmetic damage and a mechanical problem wearing a cosmetic disguise.
