I own 3 houses and one of homes was appraised by 100% in just one year... My house value for 2017 was $29,000 and this yr is $61.430. We lived in the house for 8-9 years before purchasing another home. All last yr I had renters living in my other home. We did not remolded the house did absolutely nothing to it. I am behind on paying taxes from last yr I do owe half ($500). My question is how did my home get appraised $30,000 more in one year??? 2018 property/building homesite value: $52,700/ 1,360.00sqft. Land homesite value $8,730 0.5041 acres
