I assume some books are more for introduction and inspiration (Rich Dad Poor Dad, etc.) and some are very useful as a reference and tool (Gallinelli's Cashflow and key financial measures book). 

Anything from the last two housing references?

They will be able to advise on the plan requirements, potentially giving you something off the shelf from a previous project or referring you to an affordable draftsman.

Hi BP members,After learning about the BRRRR on bigger pockets I reached out to an investor friendly lender I was referred to and asked him if he had any loans geared towards investors?

References and some due diligence into the marketing materials they provide you with.  

We have worked with quite a few contractors in Gillette, if that is where you're referring to?

They should also be able to refer you to a good lender for what your goals are.A great resource for this is David Greene's book "Long-Distance Real Estate Investing".

Just tell them to refer to their lease, it is on them. 

I am looking for any references for any handyman or contractors in the area.

The agent will also likely be able to refer you to other people who can help you, like lenders, contractors, attorneys and more.
