You may think an offer that's so far below the listing price won't stand a chance of succeeding. Not true.
As in so much of life, you will eventually succeed if you are persistent. Even during healthy market conditions, there are unit owners experiencing financial difficulty, looking for a way out. You owe it to yourself to obtain the best possible price for the unit you're shopping for.
How can I offer a low price without upsetting the vendor? It feels tactless to (ask your realtor to) do this with no explanation or soothing words.
