I pass this on to my investor clients so they can very quickly assess the max.
BTL mortgage achievable on a known monthly rental. It is not rocket science just as few button presses as poss. I thought it would be useful. Call me if you need clarification -
To work out how much you can borrow on an interest only
BTL loan if you know the monthly rental being achieved by a property.
Then you just need to know
A. Interest rate % of the proposed mortgage (e.g. 5.59%)
and
B. Rental cover needed by lender
(e.g. 125% of monthly mortgage for Mortgage Express)
So for your example where you achieve £500
pcm rental and the interest is 5.59% (if we use 125% rental cover) then -
• The monthly allowance the mortgage co. allow in the calculation in this case is 1 divided by 125% rental cover = 0.8
[1 / 125 %]
£500 per month rent x 0.8 = £400 per month rental mortgage allowance
• So if you have an allowance of £400
pcm (x 12 = £4,800 per year.)
Then all you need to do is divide this annual ‘allowance’ by the interest rate of the proposed loan e.g. 5.59% (You need a calculator with a % button)
£4,800 divided by 5.59% = £85,867 is how much they will lend.
(Provided it does not exceed their maximum stated
LTV e.g.85%)
[4800 / 5.59 %]
This is normally the actual amount they will lend as they usually allow arrangement fees to be added on top (even over and above the stated
LTV maximum of 85% or 90%)
--------------------------------------------------------------------
If the rental cover required by the mortgage co. was 110% of pay rate then
£500 per month rent x 0.91 = £455 per month mortgage allowance
(1 divided by 110% rental cover = 0.91)
So if you are paying £455 per month x 12 = £5,460 per year.
Divided by 5.59% interest rate = £97,674 loan on offer.
