How much should this gap actually matter?
That 1% gap is small — for interior house painting it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.

Cheapest time for interior house painting in either city
Exterior paint only cures properly in dry, 50-85°F weather, which makes summer both the only real option and the most expensive one. Interior work has no such limit, so booking it in winter — the trade's slow season — is the cheaper play.
What are you really paying for in a paint job?
Paint is the smallest line item in a painting budget — prep and labor are where the real cost sits. Our editors on where to actually spend.
The coverage case
Two coats over primer is the honest standard; one-coat bids hide thin coverage. Confirm coats and primer in writing so a "lower" price isn't just less paint on the wall.
The prep-first case
The finish that lasts is built before the first coat goes on — washing, sanding glossy spots, patching nail holes, caulking gaps. Skip that and the paint releases from the wall within a season, no matter whose can it came from. A bid comes in low mostly by cutting the prep hours, so read that line before you read the brand line.
The timing case
Book interior rooms during the slow winter stretch and you get first-string crews without the summer premium. Outside work can't be pushed against the weather: wait until the siding is dry and temperatures hold, or the coat fails to bond and the whole wall comes back around.
The headline price on a painting bid tells you almost nothing — ask about prep and coat count instead. Two coats over primer, done in the right season, consistently outperforms the cheapest quote.
