@Patrick Philip Most realtors opinions are **** and they cannot be held accountable legally when you make financial decisions based on their advice. Our realtor used comps from a historic district a few blocks over for our purchase which over estimated the ARV by 100k. She made her commission, we were stuck with the massive loss. You have got to learn to do your own CMA before you start doing this. My two large losses this year happened because of bad, fluffed CMA's that we went by because we bought before we had access to comps ourselves and had a general knowledge of the neighborhoods.
Like you, we were looking for an easy button. Push it, and out comes an accurate ARV and rehab estimate. We never found one. Its a skill developed by the investor.
We have never found a wholesaler who could source a good deal. If youre going to use one, find and meet in person three people who have used them first. This simple step would have saved me months of my life and thousands of dollars. Do not be in a rush to get started! It will color your judgement.
