Five Mistakes First-Time Boston Buyers Make — and How to Avoid Them

Buying your first home in Greater Boston is a different sport from buying almost anywhere else in the country: old housing stock, fast-moving inventory, and a market that rewards preparation over enthusiasm. These are the five mistakes I see most often — and what to do instead.

1. Touring homes before getting pre-approved

Falling in love with a condo you can’t finance is more than heartbreak — in this market, it costs you the weeks you needed to compete for the home you can buy. Sellers here expect a pre-approval letter attached to your offer, and listing agents quietly deprioritize offers without one. Talk to a lender first. It’s free, it’s fast, and it turns you from a browser into a buyer.

2. Waiving the inspection just to compete

In hot weeks, buyers hear that “everyone is waiving inspections.” Sometimes competitive offers do — but a first-time buyer waiving an inspection on a 120-year-old triple-decker is taking on risk they can’t price. There are middle paths: an informational inspection, shortened timelines, or pass/fail thresholds. Protect yourself intelligently instead of blindly.

3. Ignoring the condo documents

In Boston, your first home is very likely a condo — which means you’re buying into a small business called the condo association. Skipping the budget, reserve fund, and meeting minutes is like buying stock without reading anything about the company. Thin reserves and looming roof assessments hide in those documents. I read them with my clients, every time.

4. Underestimating what an old house costs to own

Fresh paint sells; roofs, boilers, and knob-and-tube wiring cost. Much of Greater Boston’s housing predates 1940, and the difference between a charming home and a money pit is usually invisible on a Sunday open house. Budget for ownership, not just the purchase — and bring someone who knows what a 1920s heating system means for your monthly costs.

5. Searching at the very top of your budget

If your pre-approval says $650K and every home you tour is listed at $650K, you have no room to compete — and Boston homes frequently sell over asking in competitive seasons. Searching a comfortable step below your ceiling gives you negotiating power and keeps your first year of ownership from feeling like a squeeze.


The common thread: every one of these mistakes comes from moving fast without a guide who has seen the pattern before. That’s literally the job of a buyer’s agent — and in Massachusetts, my representation is agreed clearly in writing before we ever tour a home. If you’re six months out or six days out, let’s talk.
