Do you have a local credit union?

Initially I would like to find a bank/credit union that lends to small time investors, but any other advice/recommendation is welcome.

I opted for the secured card available through my credit union.

Your best bet is to call around and present your question to local banks, small local credit unions, and the national SFR buy-to-rent finance companies such as B2R, Colony and Firstkey and compare terms, rates and fees.  

You would also find many credit unions to finance your property.  

Are there specific guidelines that allow certain financial entities (ie banks, mortgage brokers/bankers, smaller credit unions) to do this.

If you are at all near Union City I have a real estate proposition for you as well. 

Which are the same exemptions the CFPB recently approved for small creditors i.e. community banks and credit unions that help consumers in underserved areas access homeownership much as seller financing does.

There are numerous banks or credit unions that will do a secured card with pretty horrible credit.

Have you found a community bank, credit union, etc that will cash you out after the purchase?
