@Will McGuire you want to do the Historic Exemption as you mentioned above. Does this property need a renovation or someone is flipping it? If it is the latter, I may be wrong, but I don't think you would qualify for the Historic Exemption. My understanding of it is that since you would be improving the property, and it would be worth more post renovation, that is where you would be saving. For example- Lets say a house is assessed at 100k, you buy it for 100k, and put in 100k. The home is now worth 200k... Instead of paying the full boat of taxes on the 200k, the city will keep the assessed amount at the 100k for the 1st 5 years, then increase 20% per year of the fully assessed value for the remaining 5 years.
If you are buying someones flip, I would assume the taxes would triple. Unless they did the historic tax credit? Im not sure if this can be passed down to a new buyer or not. @Sarah Hooff may know who happens to be an excellent agent should you be in need of one.
