The Realtor has the taxes listed at $1276.00 but I am not sure of the source. The millage rate in Madison county is 41.10. At that rate with the current offering price of $399,000 I figure the taxes could be as high as $3279.00 before homestead discount. You may call the county assessor for a more accurate figure. 479-738-2325.
I am not sure about DSL but AT&T has a place online where you can enter the address and see if it is available. I tried to check but could not bring up the exact address. I can tell you that it is not available at 39400 hwy 23, which is the closest address I could search. I would call your DSL provider and give them this address to check.
The water source is not listed on the MLX but I am sure it is most likely Rural. If you would like me to contact the agent on the listing and find out I would be glad to do that.
