@Erhart Asaad there are too many variables that will impact expenses, so it’s hard to give a blanket answer.

HELOCs are based on a variable rate linked to prime rate, which is forecasted to go up this year.

We purchased during the pandemic and there were so many variables that shifted that could have tanked us. 

The rate is higher and usually variable, but the money just sits there ready to go and you don't pay interest on it until you use it.

I understand it's important to evaluate offers from multiple lenders before selecting one but apart from simply comparing interest rates and variable vs. fixed I'm not sure what makes one offer better than another.Any advice would be greatly appreciated!

There are a lot of variables.

There are some variables that would help determine my course of action. 

One mistake I made was not realizing the mortgage was only fixed for 3 years, then variable.

And... we know nothing about the mortgages again.I had commercial mortgages that were callable, adjustable, variable and bothered me for my financials every year.   

As the Airbnb laws/rules change and with the fluid of the market you really need to stand out, the thing about long term is it's a lower cashflow but there are not as many variables with the investments as there are with STRs.
