Mortgage payment with 25% down is $1,011. 

That brought the monthly mortgage to within range of over $200/month cash flow.

I can look into the assets the notes are attached to, to see if they're in decent shape or even exist if you like...... hope you're able to navigate through this dilemma!

We chose these properties for cash flow opportunity and because they work nicely for house hacking because the unit you are occupying is a percentage of a smaller mortgage payment.  

If your rate is low on the 5 unit, I might consider the possibility of a line of credit for my equity instead of an entire new mortgage.  

Consequently many inexperienced investors make investment decisions based on where they can afford to buy, not necessarily where a good investment thesis may exist. 

Definitely look into HELOC/cash out options, but if those don't work in terms of rates or availability I'd suggest using the existing cashflow from your multi to offset a primary mortgage, and then find a primary with an ADU.

There are several benefits of having cash in the bank/liquid reserves versus an open end mortgage (a.k.a) credit card.

near 0% and 0% options with DPA's exist (down payment assistance) programs.

i wasn't buying this as a start to my real estate career just to help me with the mortgage.
