*the 10yr treasury is roughly 1.35% as I write this (7/7/21), even if it triples (3x wow!)

Lenders base fixed rate conventional (15 and 30 year) mortgages off the 10-year treasury.

With banks, CDs, annuities, treasuries, and most bonds paying under 2%...I say an IRR of 10%+ is a decent play.

We diversify our treasury so as the world progresses we are looking forward to integrating more of our treasury with our active RE operations. 

In lieu of huge down payments that only protect one side I would suggest buying a US Treasury.

It can only exist until the voters discover that they can vote themselves largesse from the public treasury.

In late March 2020, everyone in Congress, at the Fed, and at the Treasury Department, were reciting the exact same thing, in unison, over and over again, like a religious incantation, when they came up with the policy-set that is mostly still in effect:"2008, never again. 2008, never again. 2008, never again."

Also if you know the census tract # of the property, then there is an IRS or US Treasury web site which has a list of all the OZ census tracts - it's downloadable into a spreadsheet. 

The treasury is running out of money and unless they raise the debt ceiling, the party is over.
