A Heloc can never be used as a PITI reserve, or an asset instead its a debt burden and an additional trade line on credit.A Heloc carries a higher risk when it comes to security meaning if you miss a payment even by mistake or for any reason, your scores drop, or your balances start to change your DTI or usage percentage.

Extensions may be granted for valid reasons, like needing more time to secure financing or complete due diligence.

I personally collect a security deposit and get the damage protection waiver for added protection.

You can be sure your guests are not throwing a wild party in the back yard pissing off the neighbors.  

You know your goal isn't to leave the 9-to-5, you have a great job with good scale and security.

While you may need to sift through less serious inquiries, I’ve successfully secured some strong deals and valuable connections through these platforms.

If you are talking about just throwing offers out there and nothing is sticking, that's a whole different issue.

More secure and stable than an STR (also less competition) but you aren't in the red like you'd be with an LTR. 

However, excessive shifting could indicate that the opener isn’t secured tightly or aligned correctly.

Do you have a way to secure more off-market deals?
