I have no idea where you get the notion that in renting you will do little renovation and get the best dollars compared to other stuff .

We are planning to charge 25-35 dollars per unit to recover the 6-7k a year we pay for water.

@Caroline Gerardo is 100% right on this topic and I can't believe an actual experienced builder/investor would suggest that any of 12 items listed would impact value more than a couple thousand dollar condition adjustment. 

They can assess a property at a smaller amount and tax per dollar value at a higher amount.

I.E. when setting it up, I put in 500 dollars, and it therefore had a $500 limit. 

You tried to do something to save a few dollars and it ended up costing you 100 more. 

There has already been a multimillion dollar townhouse built nearby to property Im looking at and I read alot of money is being poured into community.

1000 dollars each sounds about right. 

You can also hire an appraiser to independently evaluate what the property is worth for a fee, usually several hundred dollars.  

You need a place to live so in this market you'll likely pay top dollar to move unless you downsize significantly.
