I was looking at using Bluehost as their price is pretty low ($2.75/month) for their basic package and it looks like it offers everything I need.

We don't always use Lowe's for materials -- sometimes it's a local vender, a contractor, or another big box store like Home Depot or Menards.

The home and land are for sale as a package deal.

Material costs vary minimally between cheap areas and expensive areas.  

I'd like to connect with a lender that can begin the approval process and give me sound advice as to which loan package may be best fit for my needs.

Any guidance or advice from someone that understands not only RED but with a holistic and sustainable approach to the whole process, materials, Net Zero, Passive H design, etc.

The activities of wife with respect to the rental properties included, among other things, cleaning common areas, collecting coins from washing machines, performing repairs at the properties, communicating with tenants, collecting and depositing rent, maintaining insurance policies, purchasing materials for the properties, as needed, paying bills and keeping books and records for tax accounting purposes.

Some may have been sold, but a lot just disappeared from their site.There are a number of other companies doing build to rent here, but they are mostly turnkey and keep the property management piece, which changes the numbers.i have seen that with the one off resales.. but the bigger package deals are really their wheelhouse. 

.  ~$8 per sheet material so I'm looking at ~$53/sheet all in. 

You can track everything in a spreadsheet, or use whatever software package you want.
