I also noticed the area where I am looking to invest the rents seem to be dropping. 

Then I discovered RHAwa.org which for $110 a year you get access to their attorney created lease agreements along with several addendums (bed bugs, crime free addenda, smoke free addenda, notices).

If there’s a noticeable drop in bookings due to the higher cleaning fee, it’s time to revisit pricing.

I do notice I got charged a Loan Origination fee twice, each for $855, I'm feeling that shouldn't be the case.

We are noticing the same here in Florida.

You'll also want to ensure you have a good property manager to look after the upkeep of the property if you are not there to notice anything deteriorating or which may need attention.Creating an LLC in California could cost you a minimum tax of $800 every year.

The second year, they all of a sudden at renewal sent a notice that I'd be required to have carbon monoxide detectors in each bedroom. 

I specialize in renting to Section 8 (BRHP) in nicer areas of Baltimore County and noticing significantly deteriorated tenant quality.

I notice you mention updated wiring and plumbing. 

There’s not much else it can be unless it’s in really bad physical condition, which the PM would also notice right away.
