Hi biggerpockets and all investors in Philly

Currently renovating my SF property for rental in Philly. I heard that there might be a sale tax exemption program when purchasing renovation materials and etc. I am not really sure whether this thing exists. Just want to verify this info with you all local professional investors.

In addition, are there any property tax discount programs created by the city or state available to incentivize investors to invest in philly, just curious to know as well. Thank you All !
