Tracking Expenses for Tax Purposes

[Lucas A Riemens]

I am looking for advice on how best to track and structure my expenses to get the most tax benefits. Currently my wife and I own two properties in the Cincinnati OH area and have just completed the renovation of our 3 family which we live in the first floor of. We use this as our home, office, work shop, and storage for both properties. We did a fairly extensive rehab of the first floor; kitchen, bath, and floors along with the usual paint etc. Our second property will be getting some foundation work done as well as a full exterior paint and some general touchups inside. Each home is set up under a separate LLC what I am trying to figure out is how I should track/categorize expenses for the greatest tax benefit.

Thank you
