Converting Two Flats Into One Property

I have recently seen a large increase in the number of clients looking to purchase a flat located above or below a flat they already own in a building, then merging the two into one large flat. 

They do this by typically adding a staircase and then general cosmetic work. Most high street banks won’t, however, lend on this because when the re-mortgage/purchase is complete, they would still be essentially lending against two separate flats.  

We are, however, still able to avoid expensive development finance rates (often 2% lender fee and at least 1% interest pcm) as there isn’t any heavy ‘structural work’ to be carried out. A small handful of Private Banks and Building Societies are happy to cross collateralise across both flats and allow the client to combine the flats into one property, once the mortgage has drawn down.

In some cases where the client has a relatively low mortgage on their current flat, we have been able to raise enough lending secured against this property to cover not only the deposit on the second flat, but the cost of the works as weell. This means they don’t need to use any of their own cash.

The Building Societies are typically the best place to assist with this type of transaction when the lending is below £1m and the Private Banks when the lending is above £1m.

I have given both examples below on two recent transactions:

Purchasing a property - especially one that requires a large mortgage loan - can be stressful. Negotiation, understanding terms, dealing with paperwork and the different parties involved in the process is challenging. For this reason, our role extends beyond getting you the most advantageous mortgage rate and terms. Enness is here to support you throughout all aspects of the property purchasing process; nothing is too much to ask, and no task is too small.
