Talk to them when you renew the leases and be prepared for vacancies if you change a lot of things or aren't flexible (ie on how they pay rent). 

But it happens in the bond market too, and bonds are more similar to homes than stocks, they trade in large blocks, some aren’t super liquid, but still, bonds don’t have leaky roofs and you can buy and sell them way faster than you can buy and sell a home.

Smart locks are good for this, until they aren't : ) But if the tenant has wifi you can do smartlocks and give codes to contractors that are good for X hours then expire.  

I've been searching for short term leases/month-to-month options that aren't crazy expensive but to no avail.

If you aren't an investor yourself then that is the next best thing.The role of the Investor Friendly agent, at least where it differs from a Retail agent, is that the commissions are generally smaller and there is more competition for the few deals that are out there - sounds great right!?

And who said there aren't any BRRRR deals?!?!!? 

Have your broker (not your agent) call his broker.It’s off-market, so MLS and Bright aren’t going to have a say.Whether we call it an “office listing” or “pocket listing”, we don’t know whether the seller has specifically stated to not put it in the MLS.

AND you aren't limited to the size of a property based on your liquid capital.

Why aren't you interviewing with other companies? 

Your entire financial structure here seems pretty complicated and it doesn't need to be.HELOCs hurt your DTI and may be part of the reason you aren't qualifying.
