* buy a less $$$ house than the bank will approve you for
* get mortgage preapproval
* Once you are pre-approved, cancel all discretionary spending until after house is bought. No new cars, furntiure, vacations, etc. Consumer debt of any kind can affect your mortgage approval.
* in today's "soft" housing market, try to make low offers. Comps from 12 months ago will not cut it, prices are falling!
* look at the school/property takes on the house before making offer. This may vary between school systems. We pay LOTS in property taxes!
* look for houses with "fixable" defects - clutter, ugly carpet (over hardwood), bad paint jobs, cigarette smoke smell, overgrown bushes, etc. You can make these houses nicer through sweat equity. Also, avoid houses with non-fixable defects - concrete slab in cold climate, busy road, flood-prone low-lying ground, etc.
* test for radon
* To avoid heartbreak, fall in love AFTER you buy the house, not before.
* Expect to spend lots of money in the first few months you own the home. small repairs, curtains, small furnishings, cleaning, etc. Thousands of dollars!
