With over six transactions under my belt within the first six months, I was swiftly touted as the rising star in my brokerage, even landing radio advertisements.

Can they send you something in WRITING explaining HOW they will advertise your property, screen applicants and handle maintenance?

This is fraudulent advertising.

@Dhruv Patel, deals are what YOU make of them NOT what is advertised. 1.

So I advertise and screen tenants through Zillow to start then migrate to Avail which is free.

@Henry Hsieh if you advertise for #3 you will have them coming out of the woodwork.

How are you advertising the rental?

., last month's rent free)), and someone starts an application at the old advertised higher rental rate + concession but then completes the application after the change (lower rate and no concession), is there a rule for which you must honor? 

I am working with investors in the area and assist with professional tenant placement services: marketing, advertising, showings, tenant screening, income verification, move-in inspection, and tenant coordination, I cover it all. 

Regardless, you will likely be adjusting the expense base to reflect the tax reassessment (which you can obtain from the local county), insurance (from your insurance broker quote), property management fee, and usual repair/maintenance expenses/admin/advertising/contract services/utilities.
