First flip short salsme - how best to estimate renovation costs?

[Devon Dobson]

Interested in taking on our first real estate project and have our eye on a short sale that needs A LOT of work. WIthout prior experience flipping, what are the best ways to estImate and strategize how much rehab wIll cost up front (resources, professIonals, etc?)? The house has good bones, but has “toxic mold”, an old septIc, broken well pump, etc etc. Any advice greatly appreciated.
