1. Can I add the costs of capital improvements to my cost basis if the house was not our primary residence?
Yes you can. As stated previously you can add the cost of improvements to the cost basis of a residence that is not your primary residence.
2. Is there a limit to the amount of capital improvement costs that I can add to the basis for either a primary or non-primary residence?
No. There is not a limit on the amount of improvements made to a non-primary residence.
