Bought this first property close to my house.

I've never done it, but it's my understanding that not all lenders offer financing for properties held by an LLC.

Because you have to keep the same taxpayer as owner from the relinquished property to the replacement property I'd worry that the legal protection you'd want for a development TIC won't be there.DSTs have high fee but probably are the best path forward for someone who wants to be fully passive and avoid legal risk.

For small properties such as a duplex I don't bother with making sure the two delivery points are registered with the post office.

It’s going to be hard to get more than the property’s worth.

The land is unbuildable for residences and we build these storage workshops on the properties.  

Through commercial lending as an investment property.

You might find a property that is not even financeable using a conventional loan.

And I have access to value add and multi family properties if you are still looking.

Most credit reporting offered with property management software will include an ID check of some sort also.
