All of the rooms should have locks on them (and they shouldn't unlock unless the correct code is entered) and if one of them picks a lock to go in a vacant room, that should be automatic lease violation and eviction. 

By August 2023, I packed up my introverted self, moved to paradise, and two months later—BOOM—homeowner status unlocked.

In addition to this, I've had 2 clients this past year tell me they used Airdna in '22 and '23 to see projected and estimated income and was drastically different than actual income made with very comparable properties. 

Compare that to the performance of a new property (with that equity unlocked but also with a different interest rate as @Katie Ripp said).

You might be surprised with the amount of "trapped" equity you have in your current properties that you might be able to "unlock" to finance your next property. 

I know in residential lending you can get a HELOC to borrow a down payment to buy another property. Does this exist in the commercial realm? Current value of paid off property is roughly 350k , looking to borrow 75k-1...

So you just need to look at that additional $2000 - $3000 of interest each year as really being 1000 - $2000 of total new expense to your after the tax deduction.3.  

@Colleen F. unfortunately, AFAIK, there is no other resource than go to small claims court and go after her, which will take me $2-3K in additional legal fees.

You opened the front door by unlocking it and then pulling a rope that lifted a lever inside.   

There's a decent chance that if you have good credit and improve your DTI over the next year, you can put a Heloc on the property while it's still your primary to unlock some of that equity if needed.
