I have about $60k in liquid assets, and hopefully, I'll be reaching the $100k mark by fall.

Syndications are extremely risky investments where one has no control over their investment, no ability to liquidate their investment, no control, no title, and no way of verifying the investment promoter's claims. 

The closes I could come to answering this question was "30 Year US Treasure Bonds".1) Low risk2) Decent return (Currently)3) Nobody involved besides me and the best economy in the world (The US).4) And no work other than monitoring the economic climate sporadically.Now, the bigger question is "How to get to $10m in liquidity?"

And lastly we get into LIQUIDATION stage.

So banks can just say they hold for investment - which equates now to $517B in unrealized losses because of this accounting trickThe moment banks have to move these to their liabilities on the books that will suck a lot of liquidity out of the market due to fractional lending…. https://dailyhodl-com.cdn.ampproject.org/v/s/dailyhodl.com/2024/06/02/517000000000-in-unrealized-losses-hit-us-banking-system-as-fdic-warns-63-lenders-on-brink-of-insolvency/amp/?

I came across an existing note for sale from a private lender liquidating their portfolio.  

Hi guys, I am self employed with no proof of W2s, i make a living buying cars at dealer auctions and leaving them on a local used car lot on consignment, I have $30k liquid and around $90k tied up in my current vehicles, usually my  vehicle inventory is sub 11, I want to get into the real estate game but in my situation im guessing its hard to get a good deal in getting a loan, I am single, no debt or responsibilities , ideally i would like to start with a single family home but in the current market so high i would even consider condos/town homes.

If you have LTR experience you could push for an exception with compensating factors (credit, liquidity, time owning other real estate,).

Not a total answer but it's often a liquidity issue.

I do this but mostly as a way to float liquidity between investments.Its mostly for investors over 500k net worth as those with less should focus all liquidity to actual investing.
