Get your taxes done using TurboTax

As indicated by @DavidD66, you can find similar property sales at the courthouse for your county or city.  Someone there can help you find some comparable sales on the date of death of your wife's mother. In the end, you could make an educated guess based on historical records.  The IRS will accept a reasonable method for arriving at your value on the date of death if it is reasonable.
