Financing a house conversion/built

[TheLordJohn]

Hi all.

Following on from this thread -

https://www.pistonheads.com/gassing/topic.asp?h=0&...

I have a viewing booked next week and would like to start looking at how to finance this.
All (hopefully) details are in the first thread but it's a closed church, which I'd like to turn into a minimum 2 bed.
The floor space is almost 1800 Sq Ft.
Can anyone with authority/knowledge/experience give any pointers please
Bought houses before, but never bought anything that is none residential use, and gone through the inevitable palaver involved.

Thanks in advance, Stuart.
