There are multiple benefits of using a POA to list the property rather than getting a purchase agreement e-signed with a "listing clause" in it.

Most look at a Certificate of Insurance and confirm coverage limits but best practices are to (1) become added as additional insured under contractors policy and (2) understand coverage exclusions which are not going to be detailed on an insurance certificate.

So I saved an additional $2500 in taxes after the fact.

Both properties have a substantial amount of equity that’s essentially sitting idle.Would it be a good idea to tap into this equity (through a HELOC, cash-out refinance, etc.) to fund future fix-and-flip projects or purchase additional rental properties?

Additionally, I would suggest you run some financial calculations such as cash on cash return as well as any appreciation from the asset if/when you sell.

I have added new electric service, all new plumbing, an additional bathroom, remodeled Kitchen all the way down to the studs, new carpet on the second floor, and new LVP on the first floor.

However, you really have to analyze the costs and benefits to see if it's worth the trouble.

These are professionals with additional training and a stricter code of ethics.

I’d recommend a consultation with an attorney specializing in these, in addition to an accountant.

There are some benefits to having an LLC on reduced liability, but there are more expenses.
