it took me about 4 months to find the home i really wanted and then another 5 weeks to move in. i didn't want to deal with all the renovations so i moved into one that will need minor updates. i recommend buying a house with a mortgage payment that won't be more than one weeks take home pay. it really depends on where you live to know the market. in my town they have inspectors that are strict and ensure you are 100% up to code before you can sell and if you aren't and the buyer is okay with that - they have to put $$ in escrow for everything that's wrong. do your budget and find out what's really important to you. for me it was location, nice yard AND an attached garage!! i put down more than 20% so i didn't have to pay mortgage insurance.
for your budget:
mortgage
home owners insruance
property taxes
Heat
light
cable
cell phones
internet
tithing
food
gas
savings
fun
anything left over?

? then it's the house for you!
