Salary multiple on buy to let mortgage

I have been inquiring about buy to let mortgages. I have plenty equity on my first house but cannot get approval to released this equity as the total money borrowed is way above my salary multiple of 4-5 times. Is there another way of getting into the property investments?

I had to move this from Mortgages and Home Buying.

Consider your experience of refusal a blessing in disguise. The buy to let marrket if finished.
