Associated costs with first vacant land investment

[Benji Crapo]

I am looking at starting to investing in vacant land. My thought is to start in tax deed states near high growth areas and targeting municipalities or builders in the area since those seem like the largest buyers. I am trying to research all the costs associated with the purchase. I am looking to make offers on properties behind on taxes and take off the tax burden from the current owner. Besides the up front cost of the offered purchase price, title insurance, the tax bill, and annual property taxes, what other potentials costs should I be aware of (also mention any negatives to be aware of). Thanks in advance.
