How do I sell a vacant house on Long Island?

Vacant houses on Long Island often sell quickly, so the problem is usually not a long listing. The problem is what happens while the house is empty. I go back to the property and check that it is secure. The owner handles the setup before that. Confirm the insurance still covers a vacant house. I do not know whether every owner calls the insurer. I do tell them to make sure the heat works in winter, and to check the oil so the tank does not run dry.

I bought a house where that already happened. A tenant moved out and left the back sliding door open. The boiler ran until it ran out of oil. The second floor froze. At closing I found leaking valves and pipes, including in the cellar. Broken pipe was in the garbage, and new sections of pipe were under the baseboard covers. The repairs were not disclosed to me. After I moved in, the bathroom toilet would not stop running, and the washer and dryer valves had to be replaced. I did not pursue a claim. Another buyer might.
