Hey @Charles Evans, I would make sure to reference their lease and the new owners.

But you have to purchase new investment property of at least as much as your net sale to avoid tax.

Remember some organizations develop solar for their image and the feel good aspect, not the financial profit.This statement can be applied to any form of new energy development.

Nice job getting a good return either way!

Possibly also on lost opportunity costs of using ones HELOC to buy a one time gain (interest avoided) vs a lifetime of appreciation and cash flow.Just my thinking;   the best use for me of my HELOC is to buy rentals, rinse and repeat.   

Personally, If I could pull out a HELOC, I would use it to fix and flip which will typically make sense as you shouldnt be keeping the money out for that long and you can recycle it or pay it back and build off the capital that you got from. the flip.

Sell our house (~$700k) and purchase a new one in the Seattle area.

Could happen but very rare. #4 See everything you plan to buy in person.
