I am not sure what you mean by a "wholesale" offer. The 70% rule = ARV (after-repair value) x 70% - Repair Cost. If you intend to wholesale it to an investor who uses this 70% rule, you would want to sell it even lower to account for the profit you want to make (i.e., $10K). The ARV is determined from sales comps. If you need help with sales comps, send a DM.
