Calculating ARV on SFH in the Milwaukee area.

[Daniel Wendorf]

Hello, my name is Daniel Wendorf.i have been looking to get into SFH but i guess im having a hard time finding out the ARV for some of these homes based on local comparisons. it seems that there is a big fluctuation is the cost of these homes. one will sell for 120k with 4b 2bath, but a couple blocks away they will sell for 50k. how do i go about getting a more accurate number?
