Get Hard money loan to pay off debts while I get HELOC either on Free and Clear2a. or the primary 3.

A more likely scenario is you will be a landlord with a tenant, and you will be responsible for the upkeep on the rental as well as your own unit Then when your renter moves out or you evict the renter for non payment of rent you will need to pay to have the unit turned unless you can do this type of work yourself.

Increased rents during due diligence, negotiated longer term leases during due diligence, will occupy the space and pay market rents on top floor starting February 2025

A HELOC is probably the most reasonable option other than selling to make some equity available since you would have control over how much and when its used and only pay interest on how much you actually use and when.

CHA even pays more for "targeted" areas.
