Credit scores are a reflection of someone's ability to learning and understanding the rules of the game and haveing the discipline to play by them.If you already have good credit, already pay everything on time (autopay), then increaseing your limits will probably help you the most, because it gets your utilization down, ideally under 10%.Higher hanging fruits are average credit and account age (just have to wait for that I guess) and inquiries, which are sometimes unavoidable as real estate investors.  

Ideally tho it good to have at least 6 months of reserves in terms of overall mortgage payments.

You can always tap into HELOC for a safety net in the short term (not ideal) but there if you need it!

Quote from @Rod Merriweather: Thanks everyone, Ideally I’d just like a LOC & to use my property for collateral.

Any "strategies" to invest quicker than having the money to invest aren't going to be ideal for you.

Ideally avoiding capital gains tax, we've owned it for more than 5 yrs & lived there the whole time.  

That's not ideal but it's manageable with travel nurses and other MTR tenants we'll be targetting.Thanks for the data @Eric Fernwood.

Private money lending is ideal for investors prioritizing speed and flexibility, especially for time-sensitive projects like fix-and-flips or rentals.

For minimizing upfront costs, FHA is better; for liability protection, conventional with an LLC is ideal.

Ensure that the new DSCR is higher than 1 and ideally improves your financial position compared to your current DSCR.7.
