I would start with local banks that should be more motivated to loan on revitalization projects in your area.

We have never had such a combination of problems, exacerbated by the Australian owned banks.   

Does anyone know of any portfolio lenders and/or small banks that offer non-conforming investment property mortgages with 30-year terms?

I have not any luck with hubzu in NJ but in PA I got lucky on property. your competing with others and possibly the bank representative who bids with you (a hunch).

Lots of banks are closing down lower performing branches these days.

@Jessica RogersIf your looking at basing a lending decision on the project itself commercial bank financing does that.  

@William D Banks IIHey William, why not do a hard money loan?

That would put the bank at a lower LTV and they might lighten up on their requirements.

2) If the Canadian banks such as RBC see that I have a 700k mortgage already will they even let me borrow one?

So glad you've already plugged into the Bigger Pockets podcast - that was a huge source of education for me when I first started.If you haven't already, I would recommend finding a real estate agent that you trust, and also start talking to lenders (banks, mortgage brokers, credit unions, etc.)
