Quite the Quandary.. What Would You Do?

So this one is interesting.

I have one rental property, valued at $500k, $300k remaining on the loan @ 3%. I collect $2900/month, with PITI of $1700. So I am collecting $1200 per month, less capex etc. This home is in an area I’m confident is going to continue to improve. It’s within walking distance to a popular part of Charlotte NC, so won’t be selling any time soon, if ever.

I have a home in living in, worth ~$600k. I owe $365k @ 5.75%. I have someone interested in renting it out, fully furnished. I would make $3800/mo, PITI of $2600. So I would make another $1200 per month, less capex etc. This home is also in a great neighborhood with long term growth potential. Would like to hold as well.

I have $150k in VOO, which I may sell out of soon, as I’m quite bearish with the current admin’s policies & inflation possibilities. I also have $65k in a HYSA earning 4%.

I found a home for $375k that I think I could turn into a rental property eventually, after living in it for some time/fixing it up. I would have to bring ~$85k to the table for 20% down, to get my payment down to $2,000/month. I’ve always been a fan of putting 20% down to avoid mortgage insurance. I think I could get at least $2750 per month for this one once fixed. This home is also 5 houses down the street from my $500k rental property, so I know how much I could charge in rent (ballpark)

I have the option of getting a HELOC on my primary residence @ 7.5%, out to $80k, 20 year term.

Obviously I enjoy the growth potential & cash flow properties provide, but I also want to stay balanced in the stock market.

I should also note that I make $120k, and have $100k in my 401k.

What would you do?
