@Seidy Lasker Wash sale rules apply to stock options if they are deemed "substantially identical" to a security sold at a loss within 30 days, such as options with similar expiration dates or strike prices.

If we do cost segregation how much would we reduce our taxes by?

The state laws (do not quote me) appear to not let these companies increase rates (or its not easy) to pick up the losses.

Ok, if it's still sounding do-able, the next issue is that section 179 can't be used to create a business loss, so it would only reduce your taxes for the year if your rentals are operating as a taxable gain (but rentals are often at a tax loss thanks to depreciation).  

If you are on cash accounting, yes you could do that.On the other hand, you are ignoring carry-forward losses. 

I just can't accept such a constant ever increasing loss, even if I can afford it. 

Here's a breakdown of the situation:Current Occupancy: 80% (16/20 units occupied).Current Gross Rent Roll: $14,265/month.Market Rent Potential: $17,665/month (100% occupancy).Renovation Needs: 15 units require full renovation ($10K/unit), 4 units are 75% renovated ($2.5K/unit), totaling $160K in renovation costs.Vacancy Loss: $41,820/year in lost income due to current vacancies.Cap Rate AnalysisThe seller lists the cap rate as 9.59%, but this is based on the projected NOI of $119,858 (assuming full occupancy and market rents).

And you now have to file three tax returns:- partnership tax return- your individual tax return reporting 1/2 of the partnership losses- your partner's individual tax return reporting their 1/2 of the partnership lossesAnd while partnership return can be DIY-ed, it probably should not be.

When you pay cash for a $400,000 home and rent it out, your rate of return will likely be less than 6%.You could invest in stocks and earn 7% or better.You could put the money in a high-interest savings account and earn up to 5%.I don't understand why anyone would pay cash for real estate, erasing many benefits that increase the rate of return, while exposing themselves to the risk of loss (turnover costs, bad tenants, capex, etc.). 

If your portfolio is large enough, 5% is better.Now, some people believe that this diversification reduces the chances for a large gain.
