The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

Keep in mind many get investigated not all get charged or anything happens..

For example: Landlord will pay for electric, water and sewer charges up to $100 per month.

Property Management will charge $140 per month+$20 supervision fees.

I am in PA and yes, it is legal to charge late fees to your tenant regardless of Section 8 subsidies or not, provided the tenant's lease allows for them.

No charge for inspections my Banker does the inspections then we have lunch LOL..

They usually have a step down on that penalty like 3% year one, 2% year two, 1% year three and so on and so forth.So if you are buying a deal with the intention of rapidly increasing it's value in less than 24 months in order to refinance it and pull your cash out, you might want to go with a credit union for the acquisition financing because FCUs are barred from charging pre payment penalties.I could talk about this for hours about all the nuances but my fingers don't type that fast lol

For a large landlord, they can charge top dollar rent and evict quickly without caring about what's going on with tenants. 

Our process server charges $40 within the city limits.

They all think they charge too much and don't do enough.
