Using HCAD for Property Value Bid

Hi Folks,

I'm trying to buy a lot inside the loop and build on it. I already have funding secured, and am looking to submit offers.

There are a few cleared lots (no structure) that I'm interested in that have been sitting on HAR for a few months and have already had pricing reductions, and I've noticed that they are listed at far more than the HAR value for the land.

I was under the impression that HCAD was pretty on-point for land prices, but the structure valuation was much more subjective (so when you protest taxes, you're really focusing on protesting the improvements/structure values).

So, with that said…am I off base for wanting to basically offer the HCAD appraised value as my offer on the lot, especially since it's been on the market for months? (also since we're in a pandemic where lot loans are hard to get and there's a huge lumber price spike?)
