I rarely see ledger boards secured and flashed properly as one example.

That's the throwing you know what against the wall, and hop0e plan. 

For added security, consider umbrella insurance alongside the LLC. 

Also, added smart-deadbolt locks to each bedroom for extra security in house-hack situation.What was the outcome?

The company I use has patched the issue since then, but security is ongoing, of course.

If interest rates stabilize or your property value has increased, you might secure a better monthly payment.

From a credit perspective, house hacking also helps you build strong cash flow, which can make it easier to secure financing for future deals.Additionally, if you're targeting high-appreciation markets, you could also look into cash-out refinancing down the line to pull equity and fund additional investments.

I know I need to hold the security deposit in an escrow account.  

But after an exchange - sign the purchase documents with one pen and pick up another pen to sign the refi docs :)Another strategy you could consider is reinvesting into multiple properties, where you purchase the first property cash (ensures some security and concentrates the equity) and the second property with a mortgage.

my RE income from my rentals is semi-passive of course... so less active than W2 but more active than dividends or social security.
