After you approach Natwest, the lender will conduct a thorough credit check and assess your income and spending. Your bank will look for any changes in your financial circumstances since you got your existing mortgage.

If Natwest is happy with your income assessment and after satisfactory valuation of new property, bank they will issue a mortgage offer.

FAQs:

 

Is there a penalty for porting a NatWest mortgage?

While mortgage porting often helps you avoid Early Repayment Charges (ERCs), it’s not always entirely free of costs or “penalties.”

Some of the main situations where you might still face penalties when porting NatWest mortgage:

Partial mortgage porting: If your new mortgage is smaller than your old one, you might pay an ERC on the difference which is not ported.

For example, the property value is £300,000 with an existing mortgage loan of £200,000.

The new property purchase price is £150,000. Your deposit is £50000 so the remaining £100,000 of the existing mortgage is ported to the new property. This means that the mortgage is reduced to £100,000 which will be refunded to NatWest as it is no longer needed and is subject to an Early Repayment Charge.

Non-Simultaneous Completion:  If you sell your old home before buying the new one, you’ll likely pay the ERC upfront. Like most lenders NatWest will refund this if you complete your new mortgage with them within a set timeframe, usually it is 3-6 months from sell of property.

 

What Are the Costs Involved In NatWest Mortgage Porting?

Home movers may save on early repayment charges while moving home but standard moving costs are still payable like property valuation and conveyancing costs, regardless of porting. On some occasion product fees are payable too.

 

Who Is Eligible For A NatWest Mortgage Porting?

You’re eligible for a NatWest porting mortgage if:

Your current NatWest mortgage product is portable to new property. This can be check with NatWest or it is on the mortgage offer from NatWest.

You still meet NatWest affordability and lending criteria. This means NatWest will re-check your credit scoring, income, outgoing, and the new property’s value, just like a new mortgage application.

In essence, NatWest mortgage porting should not be a problem if your financial situation does not change since last mortgage application.

 

How Long Does It Take to Port A NatWest Mortgage to New Property?

NatWest mortgage porting usually takes 4 to 8 weeks. The timeline includes checks on affordability, property valuation, underwriting and then issue a new mortgage offer.  This can be longer due to missing documents required for mortgage, additional borrowing, or property issues.
