“I wrote kind of a low offer, but the seller accepted another offer without even responding to mine. I would have come up but they never gave me the chance. Why wouldn’t they respond?”
Imagine you’re the seller and you have two offers. One is low, but the other is at a good price with terms you’re happy with.
Many homesellers don’t want to risk losing the good offer by making a “multiple counter offer” or putting the “good” buyer on hold while they explore the low offer.
That’s probably what happened in your case.
The moral of the story is that if you really want a home, don’t make a low offer, especially if there are other offers on it.
