Large Mortgages – What are the two biggest mistakes you’ll make when financing/refinancing your property purchase?

Large mortgages are easy to find.

There are literally thousands of mortgage products available.

Unfortunately, many of the best options are not advertised on the internet… and even if you do have total access, how do you know which is the right one for you?

Do you need:

1. The lowest rate?

2. A high Loan to Value (LTV)?

3. A large loan (high street banks may not lend the amount you require)?

4. An FX loan?

5. A mixed mortgage, e.g. part repayment/part interest only?

6. A drawdown capability?

7. A Lombard loan?

8. A mortgage despite being based overseas?

And this is only scratching the surface. Basically, there are an astonishing number of options and many private banks will also be able to create sophisticated solutions for your specific requirements (depending on the size of the loan and your finances).

Unfortunately, most buyers/owners throw away money needlessly (not to mention waste their time and suffer unnecessary stress).

It’s not always about the rate or loan to value

Aside from the loan itself, what you mustn’t forget is speed. Sometimes this won’t be important, but there will be times when you want to move swiftly to secure the lowest price on the property possible or simply secure it ahead of other buyers – even cash buyers. Yes, you read that right.

I always recommend that you speak to good advisers before even starting to look for property to fully understand what your options are including what you can borrow; the top mortgage experts will know who offers the best combination of low rates and speed of execution.

This ranges from giving you a quick decision on whether they will lend to you at all, booking a survey quickly (the lender will insist on a valuation survey that they will arrange) and then speed of not only agreeing to lend but providing the necessary paperwork to your solicitor to allow you to exchange contracts.

You will miss out on your ideal home or that great investment opportunity if this is not handled correctly. Is that a risk worth taking for the sake of spending 15 minutes speaking to the right person?

“Jeremy introduced us to first rate solicitors, mortgage brokers and insurers. Another example of an insider’s black book that we did not have but value greatly, making our lives so much easier and no doubt saving us money in the end”. Mr & Mrs Christias

Whether you are planning to acquire a property or simply want to remortgage/find alternative finance, would it be a bad idea to have access to the best options?

Please do not underestimate the importance of this. One phone call to a really good mortgage broker or private banker will save you a huge amount of wasted time, money and stress.
