how much to paint a 1400 square-foot interior all white trim and walls?

It got shag carpet and has upholstered trim around kitchen.

In the first photo, I cleaned up the trim.

Remove door frame trim and adjust shims2.

Painting trim will cost extra.

Trim and walls both painted can be expensive.Ask if the bid is both walls and trim (doors etc..), and decide if the trim needs a re-coat on this turn.You might save yourself if just the walls can be done.But realize, next turn you may have to do trim.

Make sure to ask about lawn care, tree trimming and especially snow removal...how much should you budget for that each month. 

It was held up by hundreds of small trim nails, not glue.

my thought is that leaving window coverings to renters they will destroy the wood trim around the windows trying to install them.  

This would account for the overage, trim, and install material like underlayment or adhesive etc.Labor, let's assume boring easy to install non Craigslist special and someone who's actually insured etc. 2.00/sqft.So we're at 4.00l/sqft or 4,000.
