"don't negotiate on new homes..." Our sales agent told us the same thing - new home prices are not negotiable.
Not true.
I recently checked the Sumter county appraiser's site
Sumter County Property Appraiser to see when & for how much the 12 or so new homes we were shown during 2018 were finally so for. (sorry for convoluted grammar) To my unpleasant surprise,, EACH was sold during 2018 or early 2019 for $30 -10, 000 less than the original listing price! Only one was sold at the list price we had seen. I will never never never make a listing price offer again and NEVER NEVER NEVER believe ANYTHING a Villages sales rep tells me.
