Understanding my local tax records

[Keith Belzner]

Using the following tax assessment what is this house currently worth / assessed at, $322,500?  What is "land" and what is "improvements"?  I can figure out most of the record. Im curios to know so that when I talk to a seller I have a better idea of what its worth based on these numbers and area comps.

Base value

land: 128,200      improvements: 161,500     total: 289,700

value as of 1/1/15

land: 128,200     improvements: 259,900     total: 388,100

Phase-in Assessments:

as of 7/1/14     total: 289,700

as of 7/1/15     total: 322,500

also under the transfer information:

seller: bob

type:  (one of the following) NON-ARMS LENGTH OTHER       ARMS LENGTH IMPROVED       ARMS LENGTH MULTIPLE  

I am not sure what these mean regarding the property.

Thanks
