@James McGovern - my wife was in attendance and she and I own 20+ properties, a huge office building, have done multiple 1031 exchanges, Segregation studies, flips, private money, creative financing etc.  

Keep a few a use cost segregation studies to offset any added taxes.

Consider saving up $10-$20 per square foot over the next year.Apply the Enemy Method to find and study your comps.

As many investors are aware, a cost segregation study is a very beneficial tax planning tool that can create a very quick ROI.

The key with condo complexes is to do due diligence on each individual complex as far at whether they are warrantable, VA-approved, and whether they might be facing any upcoming special assessments or have issues with the state-mandated structural integrity studies and their reserves.

I am more than happy to share my preferred lenders that specialize in investment properties, home inspectors, contractors, landlord and builders risk insurance carriers, and CPA's that know to do cost allocation studies with my investor clients (that's how you know you have a CPA that knows real estate investing accounting).
