My concern with the home equity loan strategy is I'd still have the first home mortgage, the equity loan, and a new mortgage (albeit reduced from the down payment).

Meaning any of your Helocs can be closed or reduced at any point if any of your banks feel you are over leveraged, miss a payment, credit score drops, even by mistake it happens all the time.I would get rid of the Helocs and put some cash in your bank so you can use that versus a Heloc. 

Their inflated costs and reduced services make them an unattractive option.

@Bao Vu The purchase price and related expenses from 2023 should be included in the cost basis for the flip sold in 2024, reducing your taxable gain.

do you guys prefer to only invest in newer homes  i.e. built after a certain year to reduce the possibility of having to do a lot of reno on wiring, plumbing, etc. or does it just depend on seeing the house and determining the condition that its in?

If you work a day job in addition to your plans to pursue real estate in this way, then focusing in 1 city/MSA will drastically reduce your time spent focused outside your job, allowing you to keep your income high, your job safe, and your problems simpler.

Recently after some medical issues(I’m all good now) I’ve exhausted all my reserve funds and have 50k in high interest debt.

Using your $100K example, the 6% seller assist is far more valuable to this buyer than merely reducing the purchase price by $6K because the 6% seller assist is a $6,000 reduction in funds required to close whereas reducing the purchase price by $6K equates to less than a $200 savings (2.5% down payment + some incidentals).

I start with market rent or a little less to reduce vacancy.
