I currently have 100K in the bank doing absolutely nothing and I want to get the best bang for my buck in terms of properties/investment.I figured that if I am able to invest 100K outside my state, I would be able to buy several properties and put them to work for me compared to just buying one here in NY. 

Now, we have enough for a DP, closing costs, and taxes so we aren't banking off a high appraisal.

Also $10k in savings bank cash. 

Use personal bank loans, mortgage lenders, or private equity investors to finance deals.3.

If you are looking for a 100% risk-less & predictable place to park your money I'd suggest a CD at your local bank.

100% financing is tough...even for private lenders, unless there are compensating factors (great track record, proven successes, strong reserves, great credit score...maybe even good job/w2 income (usually not a factor for non-bank investment property lenders, but may be for a private individual)). 

Is there certain criteria for portfolio loans and are they mostly acquired through local banks?

etc..You can try to go conventional, to a community bank/portfolio lender, or to a non-bank lender for the above. 

We ending up putting 25% down on a commercial loan with a local bank.

Is there any typical reasons why the bank as not listed them for sale?
