Appraisal before flip? CPA advice

[Joe Atkins]

We are currently in the process of purchasing our first investment property, (cash purchase). It is an old farm house on 9 acres. We are dividing it into 3 acre tracts and keeping the house and 3 acres for a rental. Our CPA has advised us to get an appraisal of all 3 parcels, including the house which needs a ton of work. She says she needs this to offset the capital gains if we sell the land immediately. I haven't read of anyone getting an appraisal on the front end of a cash deal? Does this sound like good advice?
