Taxes on sale of property

[Grant Hwang]

Tax experts, please provide replies. Don't worry I won't sue you, I am still going to go to an accountant of course. Just want to be prepared with a list of questions.

Commercial property is possibly being sold for 1.5 million.
There is a loan on this property for about 500k.
So if I sold this property for 1.5 million and paid off lender I am left with 1 million, of course there are closing costs etc.

Can you use that 1 million to pay off other loans on other properties under section 1031(right section?) and defer capital gain and sales tax? FYI I am in WA state if that matters.

If it doesn't qualify for section 1031 I probably won't go through with it.
