Loan Servicing Questions

[Robere Istatia]

Hello All,

I am interested in buying a performing note. I have been looking into investing in notes but I am a little hesitant because 

1. What is the pay structure (How much I need to pay them and how frequent) and the services that Loan Servicing companies offer 
2. Is there a certain amount of minimum loans that they will service
3. In the case of a delinquency how would I go about the foreclosure process

If you can provide any feedback on these questions of mine or provide targeted links for me to do some more personal research whether it be on BP or an external source.

Thanks in advance :)
