Hi all thank you in advance
looking for buy to let advice. we have excellent credit rating and good income.

we currently have a property paid for worth 150,000 GBP (sorry foreign laptop)
a one bed flat tenanted at 400 gbp per month (this has a residential mortgage with 13,000 outstanding) can cancel pay off or swap when ever.
we have just sold a one bed flat and this will give us 30,000 capital for deposit

financial advisor is steering us down the buy to let mortgage route but we are wondering if there is a better option?
perhaps release equity in property or residential mortgage then convert to a buy to let later? (first pay off mortgage on flat) any help or advice gratefully received
