Any websites to find out property`s sqft in NJ?

I am getting pretty frustrated because every offer I have put on a property with the intention of renovating has not been accepted and when I find out how much it ended up going for my offer is always significantly lower even though most of the time I go in above asking price.

Hello guys...anybody aware of any form needs to be signed by the buyer when selling in AS IS condition beside the contract...I heard there should be a final walk through before the closing and the buyer needs to sign acceptance form of AS IS...anybody know how to get that form if exist?

I plugged a phone number into a search engine and came up with nothing.BTW I found it odd that this website didn't alert me to the presence of these two responses.

-Go to a website like bankrate.com and use a mortgage calculator to see the total cost for each scenario, and how each amortizes over time.  

Why do brokers only put properties on their own websites and pre-offer them only to a few select clients?

Check out the websites in the signatures of the people who respond to this and similar posts.

I thought it would be worth it.I got home and started searching for the guys name on BP and other websites.

Could I accept the $800 and still file for eviction due to her not paying her part ($300)?   

I have attached photos of what I would consider pertinent parts of my purchase and sale contract regarding realtor liability and mediation, as well as the part on risk of loss/insurance that reads something like if there is damage that is returned to it's former condition prior to sale, the Purchaser can accept that or has the option to terminate the contract... as I was not made aware of the damage taking place, I never had the option to terminate the contract, or accept if the condition was returned to it's original form.I emailed my closing attorney and I'm waiting to hear back, as well as waiting to hear back from my realtor as they were going to contact the seller's realtor to discuss this.Is this damage something I definitely should have been informed of?
