It depends on the market you’re in, the list price, what kind of mortgage you, as the potential home buyer, are comfortable with, and many other factors that you should weigh before beginning negotiations.
If you go in with a lowball offer, you could risk offending the sellers—and having them write you off completely. Buying real estate is all about striking the right balance.
So before you make any purchase offer, determine what type of market you’re in. Traditionally, buyer’s markets come with a lot of flexibility on price, because available inventory is high and houses tend to sit on the market for longer. Here, sellers tend to be more willing to negotiate, because offers are few and far between.
