[Dante Campbell]

Hello everybody my names Dante and im 22 years old im in the process of buying my first rental property through tax sales in my county my question is after i get the deed and the house is in my possession do i get the appraisal then or after i would fix it up to be rent ready? If i wait on appraisal until property is rent ready how do i know what banks and possible buyers will value it at? Thanks in advance
