Looking to tap into it without doing a cash out refi to replace the existing rates with current rates.

That's why we exist.

At the same time, little to no relief exists for rental owners.

There are many duplexes and multi-family existing housing available to choose from. 

New to the BP forum and joined out of curiosity for a hypothetical scenario.I know everyone's situation is different, and everyone has different needs and priorities within Real Estate.So I was curious on one of the many situations one might find themselves in.In this scenario I wanted to ask if a HELOC on either your primary or an existing rental property out of 4 total properties would be a viable strategy for acquiring practically " turn-key " Multi-Family rentals?

To get this amount through a cash-out refinance at 80% LTV, the home value must be at least $453,800 after one year.Based on your report your ARV right after reno is $425,000Add a 8% home appreciation for one year $34,000Estimated Home Value After 1 Year:$459,000Assuming a refinance after 12 months with a property value of $459,000: New Home Value (Post-Appreciation): $459,000 New Mortgage Amount (80% LTV): $367,200 Existing Debt Balance after 12 months: -$360,000 (because you have been paying interest only) Assuming Bank fees on New Mortgage: - $200 Cash Pulled Out: $7,001, allowing you to recover to pay only 7k on your initial investment of $29,790, leaving $ $22,789 in the deal.Many new investors mistakenly believe the BRRRR strategy ends after the cash-out.

Our best use for the property would be to build a couple of large estate home (8k sq' and up) and form a private estate, but, being that we are in the County with no existing zoning requirements, we could also build what we want and potentially turn it into an income generating property.

Regarding renting your existing home, you have to look at it as a business.

You'll likely pay high premiums, face lots of claim denials due to "pre-existing conditions", and deal with service delays.

Fundamentals change neighborhood to neighborhood (i.e. appreciation potential), inventory/absorption issues may exist, rogue city council members and/or registered community organizations can make neighborhoods less appealing with little oversight which impacts value and marketability.
