Where Kaison Gets Tax Data
Where Tax Data Comes From
When you add a property in a covered area, Kaison automatically pulls the assessed value, annual property tax, and parcel information from the county's public records. You do not need to visit the county assessor's website or copy numbers by hand.
If the property is outside a covered area, nothing breaks — you enter the tax data manually. The analysis works the same either way.
How Kaison uses this
Tax data feeds directly into holding cost calculations. The annual tax divided by 12 becomes a monthly carry cost during rehab and lease-up. It also becomes an operating expense in your cashflow projection once the property is rented.
Current Coverage
| Region | Data Available |
|---|---|
| Greene County, MO | Assessed value, tax rate, mill rate, parcel ID |
| Christian County, MO | Assessed value, tax rate, mill rate, parcel ID |
| Texas (statewide) | Assessed value, market value, annual tax |
Coverage is expanding. If you invest in a market not listed here, you can still use every feature in Kaison — just enter the property tax amount manually from your county assessor's website.
Why Accurate Tax Data Matters
Property taxes are one of the most commonly miscalculated holding costs. Investors often use rough estimates — "about 1% of value" — that can be off by hundreds of dollars per year. The actual rate varies by county, school district, and special assessment districts.
Getting the number wrong affects three parts of your analysis:
Holding costs. Monthly taxes are a carry cost during rehab and lease-up. Underestimate them and your total cost basis is wrong.
Cashflow. Annual taxes are an operating expense. Underestimate them and your NOI projection is too optimistic.
Post-rehab reassessment. After a major renovation, the county may reassess the property at a higher value. A property you bought for $118,500 and renovated to $250,000 ARV will likely see its tax bill increase at the next reassessment cycle.
Pro tip
Factor the post-rehab tax rate into your long-term cashflow, not just the current one. Your tax bill before renovation is not the tax bill you will pay once the property is worth twice as much.
