Regarding FHA loans, I wouldn't worry too much about them. Afterall, they are guaranteed by the US gov't to the lender. A couple of drawbacks are -- you may pay a *slightly* higher interest rate over a conventional loan, you will have to pay PMI insurance typically until the remaining-principle-to-appraised-value ratio hits 80% or until a certain amount of time passes(look at the contract to see which). Otherwise, they are a good option for new home buyers with no or little money down with good credit.
KLS said something about FHA interest rates climbing as the loan timeframe went on. That would only happen with an ARM or interest-only loan(the interest rate changes when the Fed changes). If you plan on flipping the house in a little over a year or two, sure, go ahead and get one of these - especially if you happen to live in Vegas or somewhere else where the market is climbing at a 30-40% clip year over year. Otherwise, settle yourself into a fixed 15 or 30 year loan. The interest rate will NEVER change with these types of loans, no matter what happens in the marketplace/gov't.
