I use my CC get my cash rewards/ air miles run them up during projects to conserve cash incase I find the next deal.

Depreciation can be applied not only to the property but also to fixtures, such as air conditioners, so if those fixtures are also new, the tax savings can be even greater.On the other hand, used property does not provide the same tax savings as new property because many years have passed since it was built, so it's useful life may be less, or in some cases, almost zero.

Bonus depreciation and Section 179 allowances for improvements can be utilized, with the latter, however, capped at zero to prevent negative losses.

I remodeled her bathroom, upgraded her kitchen a little and added central air and other things.
