Not a lot of people know this, but two veterans can actually merge their VA entitlements and purchase up to a 6 unit with a 0 down VA loan which is cool. 

Cool story too.

While this is a lot of money, most any mid-career professional likely has that available to invest (maybe not liquid today, but in general).  

I truly believe you are wasting your time putting it in those FB groups.I haven’t ever bought real estate on Facebook but I have bought some cool things on Facebook😊 

It would be a cool place.

I dont do them often but did one up in Washington state and it was 50% LTV on the primary and then cross collateral on a really cool Ranch in North Central Washington that was free and clear so I got a first on that as a cross.. and I would have loved to own that property :)  @Beth Johnson does a lot of seconds from what I see and like me she knows how to juice the equity portion of the deal..

If you need the cash liquid, that changes the decision 

Also, even on a fixed 30Y with no extra payments, you’re still paying down SOME principal (maybe like 5k in Y1 in this scenario).Although it’s nice to have the liquidity of 1L the heloc, I believe 2nd liens are still pretty cheap and fast to close.

I have had good luck finding cool unique pieces in local stores to the property.

It's all fun and games until there's a liquidity crisis.
