[DAVES]

In buying or selling a home or any real estate almost everything is subject to negotiation. We all know this to be true. The price for example. The seller thinks Bob got xxxxxx so mine is worth xxxxxx.
I paid xxxxxx it has two mortgages on it and I must get xxxxxxx to simply pay what I owe.
In the real world the question for the buyer to answer is what else is available and for what price. Are you a desirable buyer? Flexible as to when you need or want to move. Subject to the sale of my home or ready willing and able to pay CASH.
The laws are different from state to state. Building codes change. Here the ability to stand up to wind has changed and likely electrical and plumbing codes. Those popcorn ceilings-they used to have asbestos in them. Removing it, PROPERLY, is very expensive. Paint up until the 1960's or so had lead in it.
Our previous home built in 1948 likely had some old lead paint and with real copper plumbing, surely it was lead solder-not supposed to be used today.

In real estate only things in writing are valid The broker, who most likely works not for the buyer but for the seller tells the buyer it is under priced. It means nothing.

Spend a few bucks. Get an atty. If, you are the buyer get an inspector who you pay and so clearly works for you. Consider, getting an appraiser. Surprises can be very expensive.
