The sphere of influence is the first thing every agency pushes because it is truly your best shot of getting clients.  

These factors will heavily influence the tenant class that your property will be attracting.

“A change in any one of these market factors influences the others.”

Anyways, one day I hope I get big enough I have influence over the local government and fire all of them cause that's simply what they deserve. and yes I am not afraid of spouting this in public, because as mentioned, Many many people HATE working with this municipality.

Bring in a 3rd party that has influence over them.

You will need to move to a conventional transaction to avoid the appraiser being influenced by this appraisal.Good luck. 

the greatest book I ever read was the one I put down and went and found a deal-that book was how to win friends and influence people before that book I had read everything I could on the deals and the ways and the thiss and the that'sone Saturday I told myself I am going to look at and make a offer on a house and I did- I didn't get it or was able to buy the first six I made offers on but that is were my confidence came into place- I was learning how to make deals- that you cannot learn from a book-I hope this finds you with great confidence you will find the deal you will be successful it is a great journey enjoy it

The quality and condition of the property are going to have a great influence.

Using the money, you can either reinvest into other properties or just diversify into other asset classes.I recently wrote a BP article about rising interest rates and its influence on the housing market and real estate strategies across the country.

Also, the condition and location of the building could also influence the class you categorize a specific property.And lastly, are you surprised that a broker would categorize a property one class higher than it might really be?
