You might have experienced that due to the current bank closures clients can’t always get an appointment to proceed with the purchase. Note that I do remain open to advise all clients who are in need of a mortgage and happy to proceed with an online consultation. Advising clients online has been my specialty over the past years.

Please feel free to contact me whenever you have questions.
