This should be clarified, this home you are buying as a primary, are you planning on living there for more than 5 years? Or are you planning on selling it in 2 years for massive profits? Those are two very different situations. If you are looking into the latter then yes, maybe you should put a pause on the search. However if you are buying a home to raise a family in for the next decade, they go out and find the best home you can afford. You may lose a few dozen offer, but when you eventually win, I'd be willing to bet in 10 years the home you felt you just overpaid for today is going to be worth much more then.
You buy a house on payments not price. I've stated this before, a 3% rate on a 400k mortgage is the same as a 4% rate on a 350k mortgage. Rates were 4% a year and a half ago. This is one of the main factors for the increase in prices. House costs more but the payments remain the same.
Let me ask you this, if you buy a home for 500k now, do you think it will drop to 400k in 3 years? Well, rent on a 500k house is conservatively 2500 a month. In 3 years that's 90k in rent, more if the landlord raises rents each year (which I do). Yes there is maintenance in owning, but if you buy a relatively turn key home, maintenance should be minimal over a 3 year span.
So sitting on the sidelines gets you what? another year of paying off someone else's mortgage. Don't get me wrong, its tough as heck out there to buy, I'd be discouraged too and definitely more selective on the homes I choose to look at, but I'd still be looking. Your home could pop up any day.
In answer to the OP's post. I'm always looking and at the start of the year, I bought a new primary house; Bidding war, escalation clause, all cash, 30 day close, as-is etc. It's a fixer and we are getting closer to having it move in ready. In the meantime, I'm about 30 days away from putting my current primary on the market, and I plan to make a killing when I sell it:)
