Houses are complex systems where lots of stuff can go wrong and there are lots of opportunities for improvement. 

Are my numbers wrong?

Even if the tenant is 100% wrong and completely bonkers, telling them to pound sand because they are wrong won't likely make the problem go away. 

Then you have to renovate the property and there are sooo many things that can (and do) go wrong with the rehab process.

If so, it's probably just because the appraiser or assessor was wrong originally. 

Both scenarios are great so you can't wrong unless you start negative cash-flowing on a property.

Which is great but to me do the numbers work or not, and what are the levers you can pull if things go wrong.

And on top of everything, I think the last thing about my returns,  it’s absolutely 100% possible because it’s exactly what I’m doing and I’m not trying to sell one piece of property so like the old saying says when you assume you make an *** out of you and me so stop making assumptions if you don’t know have a clue about my intentions which really are exactly as I stated in pure nature and when I get out of it is a group of people I helped and in the future, I hope that comes in handy, and I’d like to prove you wrong so if you wanna direct message me, I’ll give you my email show you everything and show you how much of an idiot you are

Just realize that it requires many specific conditions to be met, and has much greater risk elements that you need to be prepared to potentially go wrong.

The only thing we are a bit confused on is he said you can simply "back out" of the deal if you change our mind...but how would you just "back out" of the contract if there is nothing actually wrong with the home?
