Hello @Hector De la Canal - Your question is a little too broad, so I'll give a broad answer. 

Hey Christian, I'm very familiar with the area Elmwood st Delaware park, in which you speak of  I'm Currently in NC. 

@Paul Kennedy  You.should be able to find the Inbox under Notifications and the create a message there.Currently, I have one rental in DE.

I think a lot of solar proponents miss some key elements when thinking about how solar can impact value.  

So I am taking it that the main issue is the front-end load for a Delaware Statutory Trust meant to defray capital gains taxes before the time runs out? 

Just inside PA on the DE border.

@Dan ShelhamerLook into DST's (Delaware Statutory Trust)

@Willson GuimontYou can exchange into a Delaware Statutory Trust or a Tenant In Common, but not a REIT. 

I know there are some filing fees with the recorder of deeds (Delaware), but what other fees are there?

@Connor HeimMost small dollar units of property that you mention can be expensed under the 'de minimis safe harbor' by making an election on your return.A competent CPA will ask for a ledger or detail of the supplies account and fixed assets accounts to make sure everything is where it needs to be for tax efficiency.
