If the economy continues to improve as anticipated, rates will keep inching up. Freddie Mac expects the 30-year to reach 4.7% by the end of 2014. IHS Global Insight forecasts that rates won't hit 6% until 2017.
2. The refi window is starting to close
The rate bump is already cooling off refis, but most homeowners with the equity and stellar credit to refinance have already done so.
If you didn't have enough equity to qualify, check again -- rising prices pushed 850,000 homes into the black in the first quarter, according to CoreLogic. Plus, the recovery may lead lenders to loosen up.
The average credit score for an approved mortgage has been 761, says the National Association of Realtors, up from the normal 720.
3. Higher rates won't scuttle the housing recovery
At worst, this turnaround will only dampen the pace of growth, says IHS U.S. economist Patrick Newport. A healthier economy is what's boosting prices. Rates would have to rise sharply to make a mark. "Going up three percentage points would be a major wet blanket," says Bob Walters, chief economist of Quicken Loans.
4. Once you're ready to buy, lock in
To avoid any short-term spikes, Washington, D.C., mortgage banker Frank Donnelly recommends locking in as soon as you can (typically when you sign a contract).
Most lenders won't charge for a 45-or 60-day rate lock. Pay for a 90- or 120-day lock only if deals close slowly where you live (ask your lender); the typical cost is a quarter of a point per 30 days. With a float-down option, you'll pay less when rates fall at least a quarter point. Skip that add-on unless it's free.
5. Fixed loans usually beat adjustables
You may be eyeing adjustables, which are up less than fixed loans. An ARM is the better call only if you plan to own your home for a short time.
