Rates too high to buy more houses

[Jack B.]

I bought four more houses last year. I was going to buy 2 more this year but 6% rates for an investment property make that cash flow negative and not worth it.

That said, what to do with cash on hand? 1.2 mil liquid. Paying off houses that are 3.65% rates makes no sense. 

I usually lose money in the stock market so far. Cash is losing money to inflation. So what to do with the money? Buy paid off houses out of state for 4K a month cash flow after all expenses?
