And I STILL have a ways to go to get my first social security check at 62.  ;-)  I have 8 SFR, all in A- to A areas.  

I dont allow tenants to move in without first month rent and security deposit paid by cashier check .

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

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

For added security, consider umbrella insurance alongside the LLC. 

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.

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

It took alot of calling and emailing but I secured a place.                                                     

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.
