You can refinance a mortgage typically under the following conditions:

• Conventional loans: Often require a six-month waiting period called a “seasoning period” after closing before refinancing with the same lender. However, refinancing with a different lender may be possible immediately.
• FHA loans: Have waiting periods ranging from 210 days to 12 months depending on the type of refinance.
• VA loans: Require at least 210 days or six on-time monthly payments after the original loan closing.
• USDA loans: Usually require 12 months of on-time payments before refinancing.
• Jumbo loans: Have no set federal waiting period but may be subject to individual lender policies.

There is no legal limit on how often you can refinance, but lenders commonly require a six-month interval between refinances. Refinancing usually makes sense when interest rates drop significantly or your financial situation improves (e.g., higher credit score or increased home equity). In general, the earliest you can refinance is after the waiting periods specific to your loan type, often around six months after your original mortgage closing. Also, refinancing takes 30 to 60 days to complete. Keep in mind that refinancing involves closing costs, so it’s best to ensure savings from refinancing outweigh those expenses.
