Thinking of selling my home how long due I have before buying another one.

You posted in a community for using ProSeries programs.

You seem to be lost on the internet.

You’ve come to a Peer User community for Intuit Tax Preparation products supporting tax preparation professionals using ProSeries, Proconnect and Lacerte , and you may be looking for support as an individual taxpayer. Please visit the TurboTax Help site for support.

Thanks.

I see you indicate you Prepare tax returns. You need to learn to use the IRS resources for your profession.

You can buy and sell as many homes as you want whenever you want.

Read the IRS regulation for Tax impacts:

And for Personal tax questions, Intuit's TurboTax resources are well organized by appropriate and specific topic. As are the IRS resources you should always reference.

I have seen some questions on here that surprised me, 

but this question from someone who is  a supposed tax preparer which indicates that they are unaware of a significant portion of tax law passed over 20 years ago boggles the mind.
