8' or 9' ceilings

[James Evertson]

I hope to pick someone's brain on this:

I am building a speculative (spec) home in an unincorporated subdivision outside of San Antonio. Comps in the neighborhood generally have 9' ceilings; my plans call for 9' with 2 10' insets in the LR and master BR. Neighborhood comps are ~$117/sqft.

Has anyone here evaluated the ROI of spending more putting in the 9 footers compared to the 8? I ran a couple grand over budget on my foundation and putting in the 8 footers would put me back on budget, but with what affect on the selling price!?!

Thanks in advance,

James
