When do you start to engage with Real estate services?

[Antonio Boone]

Hello BP members,

I am looking to buy my first house in 2015. I would like to close in June or July. I do not have all the money for closing cost and down payment yet. I hope to have this after tax returns in February. 

When should i start talking to Realtors, Lenders, and Real estate Attorneys?

Thanks!
