What painting pros earn in each metro
Since labor accounts for around 70% of what a interior house painting job costs, it's the biggest lever behind any price gap between cities. What you're seeing below is actual BLS metro wage data for skilled installers — not a guess.

Cheapest time for interior house painting in either city
Because exterior paint needs warm, dry conditions, summer bookings are unavoidable and pricier. Interior painting sidesteps that constraint entirely — schedule it in winter, when crews have far less competing work.
What are you really paying for in a paint job?
Two bids on the same room can differ by half, and the gap is almost never the paint itself — it's how much prep and how many coats each one includes. Here's what separates a finish that holds from one that doesn't.
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 coverage case
A quote that promises 'one coat, done' is usually promising a thin film that telegraphs whatever was underneath. Primer and two finish coats is what holds the color and buries the old wall. Put both in writing; otherwise the cheaper bid is just less product spread further.
The prep-first case
Surface prep — patching, sanding, caulking, washing — is most of a lasting finish. A bid that's cheap because it skips prep will peel within a year. Pay for the prep, not the brand name.
Where a crew spends its hours decides how the job ages: sanding, patching and caulking up front, then full coats over primer. Time the interior work for winter and the exterior for dry weather, and the finish holds for years instead of months.
