"Customary" can varie...the size of the acreage shouldn't matter that much, as it is based on a %, usually, it could actually be a flat fee, but that is less common. Land listings could be a range of 5-10%....
What type of land is it? Just curious what kind of buyer you might be looking for. Is this a buildable lot? I would be happy to talk with you further about this, feel free to give me a call..I am not that far away!
I hope to hear from you...
Not sure if you figured this out yet - I made a google map that shows part of the taconic from chatham down to poughkeepsie - livingston manor is on the southern border of the catskill state park in sullivan county (west of the hudson) while the taconic is on the east of the hudson (from columbia county down into westchester county) - I hope this helps! I made a google map but it won't let me link to it - if I cant get it to work email me through trulia and I will email it to you.... more
