Questions for SBA experts- HELOC primary residence vs rental property

Hello, Background: I am hoping to get advice from SBA experts on best course of action for me. I own my primary home and I also own one rental property. I have owned both for long time and have significant equity in both houses. I am in early stages of searching and getting my finances in order and completing preparations for an acquisition early in 2027. Questions: 1. Should I get HELOC in place now given there is sufficient time between now and applying for SBA loan? 2. What is the best option for HELOC. Do HELOC on primary residence or on Rental property or on both? 3. If I did HELOC should I draw money from it? Will open HELOC with no money drawn will be treated differently from the one with money drawn on it? 4. Can I use money from HELOC for equity? Specially if I did HELOC against rental property and if repayment is supported by rental income? 5. Is HELOC better option or Home equity loan a better option? Is there a difference in how they are treated by SBA? 6. How does this affect personal guarantee situation? Appreciate any guidance on these questions. Thanks Rajesh
