I don't know what they are but unless there's something in the city that requires that kind of notice, it sounds excessive to me.

You either have verified income and meet the other requirements, or don't. 

If you ask the manager to justify a fee and he starts hemming and hawing, move on or require them to remove the fee.

I am looking at different loan options but to break even (not having to put any money of my own in the house after the initial down payment) the current down payment required is that much. 

One of the biggest challenges for everyone involved is being on the same page about the actual time required for maintenance.DIY landlords rarely properly track their time when it comes to property management in general - tracking their true time invested in maintenance is where they perform the worst.Investors that hire PMCs are rarely any better at understanding the true amount of time maintenance takes.

For example, a $200,000 property might require $2,000–$4,000 per year.

Another option that requires more legwork is to call the servicer/ producer of the inverter.

The underwriting process is certainly more arduous than most acquisitions but through my personal experiences some of the lenders are far more knowledgeable about the requirements and make for a far easier process for both seller and buyer.

I'm being required to pay another application fee and then $600 application fee to hopefully get this approved by the Board to allow me to continue running the STR that they approved 6+ months ago. 

The claims of 1hr to collect rent, produce receipts, and deposit checks also seems like a reasonable claim if done physically and not electronically.
