House and garage don't match

[Stephen R.]

I just finished a rehab that included a total tear down and rebuild of a detached garage. The problem is that the contractor claimed he was unable to match the vinyl siding on the new garage to the house. So now the garage is white and the house is a light yellow. The contractor claims he can paint the siding of the house to match the garage but that he needs at least 2 days where the temperature is above 50 degrees and stays above freezing at night. It is February in New England so I don't know how long that would take.

My holding costs are around $3,900/mo. My question is: do I hold it for another 30 days or so and list it once it is repainted or list it now with the non-matching colors?
