Property taxes and insurance are the two largest recurring costs that catch portfolio owners off guard. Both come with hard due dates, and missing either creates real problems. Unpaid property taxes lead to penalties, interest, and eventually liens. Lapsed insurance leaves you exposed at exactly the wrong moment. Tracking these across multiple properties and entities takes a system, not a mental note.

Start with a centralized record for every property. For property taxes, you need the parcel number, the billing jurisdiction, the due dates, and the annual amount. Due dates vary by state and sometimes by county. Some jurisdictions bill quarterly, others semi-annually, others once a year. California works differently than Texas, which works differently than New Jersey. You have to know the schedule for each property.

For insurance, track the policy number, the carrier, the premium amount, the renewal date, and what’s covered. Some owners have a blanket policy covering multiple properties. Others have individual policies per asset. Either way, you need to know when each policy renews and what the expected premium will be.

The escrow question matters. If a property has a mortgage with escrow, the lender handles taxes and insurance out of your monthly payment. You still need to verify they’re actually being paid, but you’re not cutting separate checks. For properties without escrow, you’re responsible for paying directly. Your tracking system needs to distinguish between escrowed and non-escrowed obligations so you know which payments require your direct action.

Organize by property and by entity. If you own ten properties across four LLCs, you need to see both views. What’s due on each property, and what’s due from each entity. This matters for cash planning. An LLC with three properties might have $45,000 in property taxes due in a single month. If you’re not anticipating that, you’re scrambling for liquidity when the bill arrives.

Build a forward-looking calendar that shows at least 12 months out. Working with a real estate accounting firm that understands portfolios means this tracking becomes part of the ongoing work. Our portfolio and asset management service at Rock Real Estate Services maintains this planning layer above the monthly books. We track property taxes, insurance, and loan payments across every property and entity so you always know what’s coming due and can plan your cash accordingly.
