Should I sell my recently purchased property?

[Carly M.]

I purchased a 6 unit in June of 2020 for $385k and currently have $85k in equity. Since then, I have spent $25k in renovations. The monthly rent went from $4,410 to $5,450 ($5,600 is the projected rent once additional updates are made). However, since acquiring the property, the taxes went up by 32% and expenses (which I pay) such as electric, gas and water/sewer have increased significantly (perhaps due to COVID). These operational expenses are eating away at the projected cash-flow.

My strategy was initially long-term by and hold, but after looking at 2-3 units selling for nearly the same price and a 4 unit listed for $575k, selling it seems tempting. I am also considering a HELOC.
What would you do (keep, sell, HELOC, something else)?
