Church financing and mortgage

Our church model is very outdated as it was built many many years ago. It needs to be remodeled, renovated and it would be more good if it can be rebuilt.But it needs a lot of money and our church is not in that state to finance all the cost by itself.So it needs Church financing or church mortgage loan whatever is suitable for it. We need loan but at fair charges. Griffin's Church Loans is a very well reputed firm for Church financing and mortgage. So we are thinking of borrowing from there.
