6 Bookkeeping Habits That Keep Real Estate Investors Out of Audit Trouble Real estate is one of the most heavily documented corners of the tax code, which is exactly why sloppy books hurt investors more than most. Depreciation, passive-loss rules, and repair-versus-improvement calls all depend on records you either kept or did not. Good records do not make you audit-proof, nothing does, but they turn a notice from a crisis into a filing exercise. Here are six bookkeeping habits that keep real estate investors on solid ground. 1. Keep Separate Books for Each Property or Entity Commingling is the original sin of real estate bookkeeping. When one bank account and one ledger cover multiple properties, plus your personal spending, you cannot cleanly prove what belongs to which asset, and that ambiguity is exactly what an examiner probes. Give every property, or every LLC, its own bank account and its own books. It makes per-property profitability visible and, if a return is ever questioned, it lets you hand over clean records instead of untangling a year of mixed transactions. The trade-off is a little more setup and monthly work, which is far cheaper than reconstructing history under time pressure. 2. Track Basis, Improvements, and Repairs From Day One The single most valuable number in real estate, your basis, is also the one investors most often lose track of. Purchase price, closing costs, and capital improvements all adjust it, and it drives both depreciation and the gain you report when you sell. Just as important is the repair-versus-improvement distinction. A repair is generally deductible now; an improvement is capitalized and depreciated over years. Getting it wrong in either direction invites adjustment. Log each expense with enough detail to defend the treatment, and keep the invoices. This habit reduces the risk of a costly reclassification, though it does not remove the judgment that some borderline items require. 3. Keep Contemporaneous Mileage and Material-Participation Records If you claim active involvement, real estate professional status or material participation in particular, the burden is on you to prove the hours. Reconstructed logs created the week before an audit carry little weight. Contemporaneous records, kept as the year goes, are what hold up. The same goes for vehicle use. A mileage log written in real time supports the deduction; a guess does not. These records are unglamorous and they are frequently the deciding factor when a position is challenged. 4. Reconcile Monthly, Not Annually Reconciling every account monthly means a...
