These deductions can significantly reduce your taxable income.

I've previously found cost segregation studies to be highly beneficial, particularly as a strategy to offset taxable income from both my full-time employment and rental properties.

I don’t know if it would be worth it to do a 1031 after only a year unless you’re buying both properties for much less than their worth assuming 10% in selling costs (which might offfset any tax savings over just selling the contract) if the property goes from $100k to $110k by next year your taxable gain will already be zero after selling costs.if you plan to sell soon anyway  I think I’d lean towards just selling the contract and freeing up the money, saving loan and interest costs.

Any reduction in debt or cash received may be treated as taxable boot, resulting in potential tax liabilities.

No taxable event results, and the assessed value of the property remains unchanged.

With depreciation, taxable profit would be close to zero. 

your properties are showing $27,000 taxable income after all expenses?

I know this interest income is taxable, but my question is whether it is also subject to self-employment tax.

And a refinance is not taxable.
