Bonus Tip: If this quadruplex is out of state, I’d highly recommend building a reliable local team (cleaners, handymen, etc.) and maybe consider hiring a co-host or VA to help with day-to-day tasks, especially if you scale up. 

The other quotes I received were often unreasonably high compared to other properties in my portfolio—sometimes exceeding my current carrier’s increased rate for this property while offering less coverage.

If you get in with a locked in company that's in it for the long haul, your success and being taken care of are gonna be pretty high. 

I paid about $1,500 for the installation of a high-quality 4-security-camera system, which can be monitored by both the tenants (and you!)

We ended up not moving there and decided to sell it.

I did not end up joining.   

This was a highly successful transaction.

Currently, I am looking at Hemlame for local, I tried to use them for an out-of-state investment property, but the cost with an agent would end up far greater than a full-service property manager.The dream option would combine all accounting, bill pay, rent collection, provide eviction services, and maintenance coordination outside of normal hours.

My point is that in my case I believe was a problem of the loan officer who I ended up using once more.

@Ryan Rabbitt Did you end up pulling the trigger?
