I am partnering with a seasoned broker who has successfully sourced several flips for me this year so he has earned trust and credibility.  

This would be at a local community bank so I may not even have to wait the full 6 months seasoning.

Everyone there is always willing to help in any way they can (which I've heard from seasoned brokers, that is not normally the case).

It's a personal goal actually.When a seasoned investor holds out for 2% in a good neighborhood and eventually gets a property every now and again I don't see how it will keep rents from rising or property values from appreciating.   

Your rehab may take longer than you think and more importantly you may find lenders require 6 months of seasoning before they are willing to do a refinance.

And since we only buy under value, we can (usually) get them to appraise high enough once the property has seasoned (usually a year) that we can refinance out our entire loan with a bank on the back end and substantially reduce our cost of funds.But with buy and hold (as with most real estate), finding capital is the hardest part.

Have I already missed the busy season?

I'm doing rate/term refi's with the local banks today and they're requiring no seasoning.

 ^ Please a seasoned pro correct me if I am mistaken but that is my understanding. 

The interest rate will be a little higher and for a cash out refinance, they will require a seasoning period usually, probably about a year.
