I talked to a modular home company in my area, and he said to build a 4 / 2.5 2200 square foot home would be 215k, and then foundation and utilities would be another 160k.

Is there a possibility of getting utilities to the place?

Replacement homes will be climate hardened, smaller, functional and include consideration for the type of infrastructure, architecture and sustainable/durable materials utilized. 

As noted above, up to 50% of gross rental income normally gets eaten up by expenses (taxes, management fees, utilities, landscaping, repairs, capex, etc).

This property is gonna cash flow over $1000 a month after we're all said and done with utilities mortgage and more.

If the didn't do that then they have converted to LTR or MTR rentals at a steady monthly income and have the tenants take over the utilities which offsets the loss of more income.

Did you have taxable income that could’ve been reduced utilizing tax strategies?

Utilities paid by me or lawn mowing and snow, realtor commission for renting, legal expenses etc.  

Does that include utility service to the house, a driveway, septic and well? 

Specifically, I’d love to hear about best practices for managing shared spaces, screening tenants, and setting up house rules.Additionally, I plan to split the utilities among the tenants—any advice on how to handle this efficiently would be greatly appreciated!
