Need help finding Software to do Market / Time Adjustments

[Tom D]

To the poster, i absolutely agree with grant. But i would rather have a spark program that has a linear line or 4 other non linear line to pick one from. I'm not spending more that a couple minutes trying to figure out, even each quarter. I don't have that patience, since now a days the market line can be interpreted different ways. But grant is doing it the cost effective way for him. And it gets a passing grade. I look at time productivity, not cost of program, including aggravation as being part of cost.

This is one of sparks old time charts, which i use.

This is a linear time lime from their new program. Put a nice page in the report, and puts the numbers in the grid. It also has a quarterly chart. Now that's productivity.

A linear , which is not always a straight line in one direction. can also be broken down into quarterly or six-month segments ( bolstered by other evidence ) to make rising market condition adjustments for the first half of the year and none for the stable second half of the year ( for example )

I reject the idea of monthly different adjustments except in extreme cases, because that is about price and not about value, there is no measurable trend found in one mere month, and any one month can show lower or higher prices than the other months and one or two sales can influence that.

You know you can't talk about [market] value without price. Price, coupled with property feature measurements, is your evidence of value. Yes, you could pull in the Cost and Income Approaches to test the reasonableness of your value conclusion by the SCP. Of course, you can guess as well. But price - that is going to be your foundation for MV.

Sale Price typically changes over time for a variety of reasons. And, there can be many reasons such as: (1) Changing interest rates, (2) Changing employment conditions which can be local or covering broader areas, (3) Changing industrial and service industries, (4) Changing economic conditions such as recession, strong growth, etc., (5) Changing demographics, and so on.

You have made a mistake here by thinking that the "real" value is necessarily independent of price. You can think that, but it will never be more than your own opinion. You have to convince an impartial jury of what the market value is with evidence, and arguments about the so-called "real" value of a property are just arguments. The jury wants objective evidence.

Don't fall into the trap of giving "real value" priority over sale price data. Someday, maybe it will become a dream come true. But, we haven't reached that point
