I've had people who don't care about saving money or investing and just want to go as green as possible no matter the cost.And yes, creating panels, batteries, wires, the shipping and eventual disposal still takes a toll on the planet.

Because you can do both , you should take the tools and advantages at your disposal and use them. 

100k is a nice chunk of change to have at your disposal.

We assist investors in locating, acquiring, operating, and disposing of income-producing properties in the residential to commercial asset classes.

I am typically on the road most of the year so that hinders my real estate investment, but it also allows me the disposable income needed for most real estate investments.

I disposed of a 4 unit building original purchase price was $262,000 Sales price $502,000.00 total proceeds to 1031 intermediary was $240k.

CCA is calculated differently for different asset classes and, for buildings, differently than how depreciation is calculated in the U.S.A. for taxes.If you do claim CCA on an asset (property), when you dispose of that asset, there will be a recapture which may result in taxes due.After all that, you should consult with your accountant when deciding to claim CCA or not.

@Vinh Huynh you should dispose of this property.

If its not about the money meaning if he can afford to have a living situation without renters and doesn't care about investing or saving up money or having more disposable income.
