We don't want to work in the US and do have home in Canada

However we want to stay in the US longer then six months we have property and live off the incomes so we have the finances to take care of ourselves without working any suggestions on what the best way is to go about this

if you don't care about Cdn healthcare (you lose it after 6 months, or 7 months for OHIP, outside canada within any 12 month period), you can simply go back to Canada for one day every 5-6 months and come back. Carry iron-clad proof of your maintaining home in Canada, your income, and your dates of departure from US.

Then, it will be up to border officer to allow you to enter or not.

You should also be prerpared to be declared a tax resident of US, and CRA will declare you departed from canada, subject to departure tax, etc.

That might work once or twice.

we have property and live off the income

Where the properties are is also important. If they're US properties then effectively you are operating a US business, you cannot do it from inside the US as a visitor. Some caselaw I remember reading some time ago where someone got into trouble doing that. You are effectively engaged in a business, not the same as having a vacation home that you rent out when you're not there.

If you keep leaving and entering every six months, CBP will eventually deny you entry as they won't believe you have non-immigrant intent anymore based on your duration of stay. If you move your tax home to the US then you can't really effectively claim you're just a visitor.
