Investors & landlords

Thank you for your help.  We actually built this - purchased lot, built home, and sold it.  Unfortunately, we ended up holding about 9 months longer than anticipated, and those holding costs essentially negated the anticipated profits.  I am specifically wondering if we are allowed to recognize the entire loss in one year or if we are somehow limited.  I believe we are all active members, not passive.  The partnership files a 1065 and sends the individuals K-1s.  One partner files Schedule C, and the other two are salaried employees outside of this business venture.  Trying to get a jump on planning for year end, especially for the Schedule C filer.  Thank you for any additional insight!
