Advice on financing options

[John Ingallina]

Looking for guidance from this amazing group:

Opportunity to purchase a condo for a STR that will not quite break even from a cash flow metric (obviously depending on financing option), but I'm good with that. Appreciation, tax benefits could make it a sound, long term investment. I have options financing. Here are some details:

- HELOC on my primary, paid off residence (current rate 8.65% could be used to do an all cash offer.

- I have a second home (condo) with no mortgage that I could also take a mortgage or HELOC against, but not for 6+ months as it was just purchased.

- I could go traditional loan, using primary home HELOC as down payment, so effectively carrying two notes (down payment with higher HELOC rate, balance with current mortgage rate).

- credit score is above 800.

Any guidance on above options or ideas on other financing scenarios would be greatly appreciated.

Thanks so much!
