Hi Camille, I must warn you about online home valuation. They are typically incorrect because they pull from town records that are usually out of date. The online systems also don't take into consideration updates and condition unless that information is manually inputted. The best way to get the most accurate information is to have an agent do a comparative market analysis. They will use the data from the MLS along with there professional opinion. As a buyers agent I provide this service to my clients anytime they want to make an offer.
I always encourage making an educated offer based on recent sold data within the subject homes immediate area (if possible) and what you the buyer feels the home is worth after seeing others in your price range. This way you can show the seller you have done your homework, it strengthens your negotiating position. One last factor to consider is supply and demand. There may not be enough sold data in an area to help you determine a fair offer, you then have to think about the appraisal. If the home doesn't appraise for the number needed to get your loan you will have to decide if it's worth putting down a little more cash to offset the difference. This is done quite often when a buyer really wants a home. Hope this helps!
