Builder offering big discounts to select buyers

Paying different prices for same model creates tension

DEAR BENNY: We recently purchased a new home, only to find out that two weeks later the builder had offered substantially more of a discount to other buyers for the same model we had purchased. This has continued to date, but we were told there were no more discounts, all the while the builder was offering discounts above and beyond what we received. Is there any recourse I can pursue in this matter as I am left with hardly any equity in a manner of less than two weeks after I closed? –Raj
