I'd try to find something closer to turnkey, but make your space comfortable.

I purchased it to live on and to be a long term investment.

That seems weird to me and would raise red flags for auditors and I want to persue this in the best knowledgeable way possible.  

I'm going to reach out to the broker but don't want to sound too much like the noob I am so I'm curious that since these are being sold together, will I have to look at two separate loans/closing cost or is there a way to do a package loan?

To me it does not make much sense to refinance personally.

I'd be interested to hear any insight that cash flow investors can share about Casper.

I’m currently working on 58 unit BTR development project and seeking one or two private debt investors to help fund it.

Has anybody used BP business membership to generate leads for their business?

Simple, connect with those that " handle it all" YES that simple :) I know many from around the world that do absolutely nothing but close, everything handled for them Good luck 

Those are the biggest things that will protect while you are getting started on this project
