Code § 453 (l) (2) (B) (ii) (II) which states "any residential lot, but only if the taxpayer (or any related person) is not to make any improvements with respect to such lot."  

This stands in direct opposition to a capital intensive industry such as manufacturing where employee and owner skill may be less important than the company's fixed asset profile.While S179 is a valid strategy in the attempt to drive a taxpayer's taxable income below the 'threshold amount' so the SSTB receives the un-phased out Sec 199A deduction, a SSTB may not have the investments in fixed assets necessary to drive them below the threshold during the year unless they're already very close to the threshold.Some other ideas for taxpayers owning a SSTB to lower their taxable income:Roll taxable bonds into tax-exempt bonds.Life insurance & annuities.Real estate (it's BP after all).Oil and gas investments.Charitable gifts (including CRTs).Gifts to taxpayers with lower taxable income (powerful option is to gift a percentage of the business to a trust).If a SSTB is well above the threshold, a compelling case could be made that the business should be a C Corp in the current tax environment. 

Have you been making estimated tax payments?

This makes an investor wait possibly three years and most likely with an interest rate lower than 12 percent while it keeps the taxpayer in the property for at least 3 years with option to pay that lower rate at anytime.

@Tchaka Owen It's advisable that a taxpayer carry adequate and appropriate insurance for the business line. 

Let's also not ignore the fact that wholesalers are taxpayers and the majority get CPA's on board immediately after they assign their first contract. 

. §1.165-9(b)Property converted from personal use(1) If property purchased or constructed by the taxpayer for use as his personal residence is, prior to its sale, rented or otherwise appropriated to income-producing purposes and is used for such purposes up to the time of its sale, a loss sustained on the sale of the property shall be allowed as a deduction under section 165(a).(2) The loss allowed under this paragraph upon the sale of the property shall be the excess of the adjusted basis prescribed in § 1.1011-1 for determining loss over the amount realized from the sale.

@Curtis MaagSection 121 exclusion is given to taxpayers who sell when they lived and owned the property for 2 out of the last 5 years.The exclusion is $250,000($500,000 if married filing jointly). 

When an IRA receives income from a trade or business on a regular or repeated basis, it can become subject to a tax known as UBIT which is meant to level the playing field and protect tax-paying businesses from unfair competition. 

not reallyAnother level of complexion is losses that are passive may not be utilized to offset your other income while some taxpayers can. sometimes it's best to keep things simple.
