offer, counter offer, counter offer, counter offer, counter offer

here is the situation.

we fell in love with a house. it was priced too high. we made an offer for considerably less than the asking price.

they counter-offered. for more than what we want to pay. but they came down quite a bit.

we have driven by the house obsessively, picturing our unborn children playing on the porch. we took mercy over there and she peed in the yard (she likes it). don't worry, the house is vacant. today, we see that they have added furniture to the sun porch, flowers on the deck, and art on the mantle. they are trying to SELL the fucker!

so do we counter offer again? risking that someone will make another offer in the meantime and we lose the house? and knowing that they might not come down any more? or do we just say fuck it and pay a little more (we're talking about 2.5% more) than what we said we would be willing to pay?

dear universe, please advise me.
