By the time you are 35 you could be financially independent and wealthy.Too many Americans, particularly young Americans, want everything now.

Debt is rarely a factor in their issue. the ultra wealthy I know  with a few exceptions have very limited debt.. to no debt. 

Selling gets a tax free gain and allows you to be more liquid; keeping it allows you to have once in a lifetime cheap debt and have that leverage on an appreciating asset. 

Using HELOCs or IBC to pay off debt (simple vs amortized debt) method is effective, yet investing in assets such as rental properties or syndications might be a more strategic use of available funds than debt repayment.

Debt will get paid down, rents historically will go up, and values historically will appreciate. 

Can you do side hustles, cut down costs to get rid of these debts?

You'll likely also reduce your cost of living by moving to a stabilized apartment.Depending on the cashflow and debt paydown, you can use this strategy until you've built enough equity to reinvest.On the other hand, getting into a multi-family after refinancing will also help you build substantial equity to rinse and repeat in the coming years.

Now it's an out of control machine with a lot of financially incestuous relationships in the tupperware farm.

Prioritize your financial stability.

Just make sure the numbers work for repayment and your overall financial goals.
