What stage to get an attorney involved

[Dave G.]

Hi. I am working on my first deal. I'm making unsolicited offers on houses that are distressed in my area. I'm trying to understand the timeline of events and who to include and when. 

1st Hurdle: Get them to read the letter.

2nd Hurdle: Get them to show me the house. (with Contractor or Inspector)

3rd Hurdle: Make offer. (Do I need to consult with an attorney before making an offer?)

4th Hurdle: Signed purchase agreement (The attorney will draft a purchase agreement)

5th Hurdle: Closing (How long before closing should I have the the Title company picked out and hired?)
