I wanted to help you out by giving you a the summary of the Cupertino area.
There are currently 37 active homes on MLS that match your criteria, excluding price. Setting a max price of $800K reduces that number to 4, of which the cheapest is an excellent fixer opportunity for $698K.
To go one step further, since everyone knows how little inventory there is in Cupertino right now, I pulled all of the sales for the past year (matching your criteria) to see what has sold before the inventory crunch of 2012.
There were 485 sales all together (if we exclude price) over the past 12 months.
If we set $800K as the max, there have been 48 sales.
If we set $700K as the max, there have been 19 sales.
If we set $600K as the max, there have been 4 sales.
And finally if we set $500K as the max, there have been 0 sales.
Of course, these are MLS transactions, not private sales, so perhaps the private sale statistics can be adjusted by 7%... which would not change the results in any significant way.
Prices today are higher than they were last year, and the market is more competitive than ever because sellers are greedier than ever. It's a rare seller today that doesn't want to list their home and have buyers bidding up the price vs selling it as a private sale and not getting top dollar.
My goal is not to discourage you, but to help you set realistic expectations if you are expecting to buy a Cupertino home for under $500K.
That being said, if you raise your price to at least $700K, I know I can help you find the fixer upper you're looking for... even in this ultra competitive market. As you can see I'm very familiar with the Cupertino area, prices, and inventories, having worked with many buyers in the area.
Hope this saves you some time, since after all, time is money :-)
Let me know if there's anything I can do to help!
