There is no hard rule of thumb answer to your question. What you need to do is study what other comparable properties have sold for , and that should help guide you in your opening bid.
Length of time on market and all price reductions. I have been in involved in sales that have closed at list price, and others that have sold 100,000 below list. Carefully examine the history and the market to achieve the answer on a case by case basis.
1) History- How long has this property been on the market & at what price.
2) How much did the owner pay for the property? Are they up-side-down?
Motivation is the key!!! I good agent can help you!
There is no "typical" offer price. What is most important is what the most recent comparable home sold for. If a house is well priced, as compared to recent sales, buyers see the value and make initial offers close to the asking price. In some instances, (2 in the last 3 mos. for me) buyers paid full price and above asking price on properly priced homes. If you truly like the house, and the comparable sales are there, make a strong initial offer. Well priced homes sell fast and often at asking price.
1) Days on market at current price
2) Days on the market as a whole
3) Seller's personal situation- every seller's motivation is unique (i.e. Divorce, Short-Sale, Unemployment)
We were just talking about the home prices in Rockland. There are areas such as New City ,Nanuet, due to the excessive number of inventory, the homes stay in the market longer and sells about 8% below asking. Remember, agents price homes to sell these days due to market condition and bank restrictions. Rivertown community is holding the prices pretty strong.
Please let me know if you have any more questions.
As stated before it all depends on the home and it's desirability. You can offer anything and these days you won't insult anyone but to be fully informed and protected having a buyer-broker/agent on your side is the way to go.. (usually there should not be any added cost to the sales price or to you as the seller pays the commission that is agreed to prior to listing but definitely ask as a few agents do charge a fee.
