DMP finished - LTV?

Hi there. My partner and I started a DMP on the 1st of September 2014 and we completed June 2017 and have zero debt. We sold our property in summer last year and decided to rent whilst we continued to save and wait for our circumstances to improve, ie be offered a better LTV and for our credit scores get better.

Our financial advisor advised that we would need to wait for around 3 years after the DMP finished before we would be offered a LTV of 90% which would mean next summer, however a property has come up that we really like. I wondered what the chances are of us being able to get a mortgage with a 10% deposit? The property is on sale for £300k and we have £30k in savings.Salary details. Mine is £28k and my partners is £55k.

Could we approach a mortgage broker? And if so, is there a particular type we need to contact.
