Offer denied, now what?

[Abraham Anderson]

I made an offer on a multi family property; the asking price was $795K, however the tax appraisal is only about $480K. so I put in a offer at $550K. The property has been listed for almost 2 years

I don't have a RE agent, I went directly to the selling agent and made the offer. She came back today saying "the purchase price needs to be much closer to the asking price". No counter-offer was submitted.

I thought about waiting a couple days to reply (so as not to seem eager), I'm a little annoyed they didn't even counter. Now what?
