GOT CASH COW MULTI UNIT

Hi,

I found two cash cow multi unit apartments in New Brunswick Canada for a total of $150,000. All of the 11 units are rented and yield a gross annual rent revenues of $70,000, after expenses net income is around $40,000 and this leaves a lot of room for mortgage payment
I want to close a commercial mortgage deal for a max of %10 downpayment but TD Canada only bank I contacted so far asked for %25. How do I find a mortgage based on the rent revenues - appreciate any suggestions.

Thanks

Murat
