I grew up in Browns Valley, and it was/is lovely. As with any area, sellers in general are slower to accept price declines than the buyers who are embracing them. Put yourself in their position and I'm sure you can see the "human nature" aspect of this conundrum. Perhaps the properties you are making offers on are already at or near market price, which could be one reason you find them appealing. Maybe that is why the sellers are unwilling to budge too much. How long have these particular homes been on the market at this price? If they've been on the market for months with no price adjustment, then, yes, the sellers are probably unrealistic and/or unmotivated. However, if the homes are relatively new to the market, or the sellers have recently lowered their price, then they probably believe they can get their asking price, and they may be right! Best of luck to you.
For some real numbers, I grabbed all the home sales since June of this year that are within a half mile of the contingent-in-five-days home I mentioned above. Here are the percentage price reductions, not from the listing price, but from the original price which often starts out unrealistically high and is then lowered to a listing price that brings offers:
91% 86% 99% 89% 91% 97% 94% 99% 96% 100% 90% 89% 94% 79%
Only one home went for 100%, but there were several at 99%. The lowest number at 79% was for a home with an unrealistically large original listing price in the $1.5 million range, so even at a 79% discount it was well over a million dollars. On that seller's behalf, the depth of the decline in prices was not yet apparent, so they were pricing based on recent trends.
That being said, now would be a good time for you to start aggressively pursuing the houses you want in the neighborhoods you want to be in. Work with your buyer's agent to start turning up people who aren't actively selling but who know the value of a live buyer. I never hesitate to send home owners letters on behalf of my buyers asking them if they would entertain an offer.
It's a numbers game. When you are persistent and embark on a campaign to find a home you will succeed.
