Do not refinance a primary residence for this because you will be increasing your payments, but not getting anything for it unless the investment you purchase is giving you such a great return that it doesn't make sense not to do it.I have used HELOCs on both my primary and investment properties (when I could get them) as short-term debt.

A cost segregation study looks at a property you own to breakdown the various assets you purchased.The goal is to increase the depreciation expense by finding assets that have an asset life less than 27.5(residential) or 39 years(non-residential).Whether you should get a cost segregation study done is whether you will benefit from the study.Will you be able to use the added depreciation now or in the near future?
