Factoring Property Taxes into Comparative Market Analysis

[John Foley]

Hello All! I am a newbie and I am conducting a CMA on a local property for sale and I am going to reach out to the agent responsible for the listing and ask if I can compare my numbers to hers.

Property taxes here on Long Island are upwards of 15-20K a year! I know that the higher the property taxes, the less the buyer will want to pay for the property, but how can I characterize this? How much less will the buyer being willing to pay? I know that the answer is largely dependent on the financing method the buyer chooses.... but does anyone have any advice?

Thank you in advance!
