Costs of attorney for seller finance contracts

[Marcelino Latina]

Hey BP community! 

I have a property that I can obtain using seller financing. 

- Is it necessary to use an attorney during the process? I do not mind paying for the costs of one if the community says and will protect everyone involved in the traansaction.

- How much is it to typically work with an attorney during the seller finance process?

- I've inquired from a few law firms and costs so far would include initial consultation, drafting purchase and sale agreement, creation Deed of Trust and Note

- Each of the above with their own costs

- So what is necessary and proper to pay for? Are there other costs I should be aware of? Or does the above sound pretty routine and standard?

I appreciate all the help I've received so far and will give back to the community  but I am very much a newbie investor at the moment.
