when can i use 1031 exchange -need advice

[Bo Qosja]

hi - purchased my property in January 28th and just sold it and signed the contract on 10/21.  Just spoke to a 1031 exchange lawyer and he said that this is not a good scenario and I cant do a 1031 exchange, that i did not hold the property for long enough time and i would surely be audited by the irs if i did this.  Does anyone have any advice? how do you guys do it? the profit is around $100k so the tax hit would be huge. I am planing on purchasing another property right away.  Not sure what to do here. Any advice would be appreciated.
