Quote from @Bob Dole: All,Apologies for the newb question, but I just heard about cost segregation and have been reading up about it online.My understanding is this (and please correct me where I'm wrong):Pros: -accelerate depreciation, front load (vs. just a straight line over 39 years) -save money on taxes because of the depreciationCons: -if I sell the property, the recapture will be larger -not recommended if you flip propertiesSo hypothetical situation:-Majority of our income is W2 based, let's say it's $500k-Net income from commercial rental is $100k-Income from dividends and interests is $100k-Both of us are full time W2, so non-prof real estate (but this can change  -- please see below)So we're hypothetically grossing $700k a year.
