Real Estate Agent vs. Real Estate Attorney

[Stephanie Knox]

Hey everyone! I'm looking to get  my first investment property - so far I sat down with a few credit unions and 1 corporate bank just to see what each one has to offer and just get pre-qualified; based on my 3 credit reports that were looked at, they're saying that I'm a sure approval (for how much I'm not sure yet.) But I was thinking it would be a good idea to get a team together so that when I get an official approval I already know who I want to work with and not waste any time. 

My question: is it necessary to hire a real estate attorney during the buying process to look over documents or should I just go to them after buying and it's time to draw up leases? and what are some things that a attorney will be able to do during the buying process that a real estate agent can't? Thanks for any help.
