I am not suggesting that the seller didn't do anything wrong but I am saying that you as the buyer are responsible for confirming all of the details of the transaction are correct before you close.Now if the seller straight lied to you that is a different story but if you neglected to confirm this then I would say you excepted this situation by closing. 

The key lies in the business plan and intended execution.

On the tax statement there is an “assessed value” which the assessor gives your property.

I will plan on contacting the county assessor and see if I can gather some owners' information otherwise I could try the walk-around and speak to neighbors approach too.

I won't lie, it can be frustrating at times to work together and be together especially running 2 companies with 30+ employees, in a very competitive field, having/trying to be the best nationwide at what we do, getting known for it, dealing with 300+ clients...We compliment each other and we cancel each other out.

@Dean Colias if I told you yes without seeing an actual loan application and numbers in front of me, i’d be lying to you.

You can also call the county's tax assessor where the property is located because that's considered to be public info. 

I pull assessor data (with a direct link) of the type of properties in the areas I want and send ALL the property owners an offer.

As for whether or not a realtor can lie about the sales price- I suppose if it's verbal, they can say whatever they want and consider it a negotiation tactic- it's unethical, but they could.

So I would not automatically assume they are lying, but I would be diligent in following up on both sides.
