@Mario Niccolini There's quite a few asset types and strategies that fall between SFH's and 20+ apartment buildings.

I guess they are the same Taxes so it makes it easier.

Certainly more areas with lower property taxes.

Here's a good breakdown of your options for tax collecting starting Feb 1 based on the new regulations.

Is it as simple as getting the site designed and engineered for the footprint, cleared and graded (all of which I am comfortable with), and then hiring a GC to build the building?

There was a news reporter at the sale and they interviewed the high bidder, who admitted that they had not seen the property, but were certain that they would be building their family home there. 

Self-Directed IRAs (SDIRA) or Solo 401(k)s allow tax-deferred or tax-free real estate investing, though they come with IRS restrictions.

Hi Chris, I've never met any one in the Atlanta area that builds to rent large scale.  

Do you know how I should go about to find  a trustworthy and fair GC for ADU build in North Hollywood?
