I am planning to buy a house in California Area.
Thinking of taking a loan from a bank or any loan provider

Is it a good idea?
1. How can i manage to get a loan with less interest? I have a good credit history
2. Reaching out to real state agent for buying a house, is it a good idea?
Is there any other way than reaching out to real estate agent for this?

I have no knowledge on this sort of thing.
starting from sajha. :)
Any appropriate suggestion will be highly appreciated.
