Are you in California? If so, let me do the financing for you.

If you are planning on buying and want to sell for profit at some point in the future, avoid 1st time home buyer programs
if they limit your profit margin.
Get the seller to pay the closing cost and refund you for any repairs that need to be made (ie. carpeting or paint)
Ask your realtor to find out everything about the property that they can (such as, crime statistics, what was the land zoned as before the house was built<if new>, etc etc.)
DO NOT purchase a house where the payment is more that you can afford comfortably. There are tricks to paying a home of quicker, but I have to goto work right now, so I'll tell them later if you want to hear.
use the next few months of hunting to really clean up your credit as good as possible(it takes 3-6 months) so your FICO score is as high as possible <--IMPORTANT
thats all I can think of off the top of my head, but happy hunting for that perfect home at the perfect price.
