Ground up requires solar panels and usually appraise better, but modular homes are cheaper, require less on-site construction (usually 2-3 weeks only), don't appraise as high, and tenants cannot tell the difference.

Thanks Allan,I'm going to look into panelized construction, with the thought that I could have some control and customization of design, but would benefit from the economies and efficiencies of offsight building. 

I installed all new electric, majority new plumbing, split the utilities for both units, new panels, updated the exterior, etc.

I personally got my electrician to check it out and found that my control panel was not getting enough power.

The downside is there is only one electric meter/panel for the whole house and there would be one bill for both units which includes heating/Central AC/electricity and so forth.

NEW kitchen with NEW white Shaker cabinets AND quartz countertops, NEW wood laminate flooring, UPDATED bathrooms with NEW matching white Shaker cabinets, NEW plumbing, NEW bathtub, shower and tiled floors, All NEW drywall, NEW electrical panel, NEW electrical wiring, NEW siding, NEW windows, NEW roof, FRESH landscaping front side and back. ...

One of my tenants works for company that installs solar panels.

I have only used pemb with my builds with traditional metal panels.

We have a panel of Home Inspectors who will be discussing Inspections, as well as answering any questions the audience has.

Before I commit I will see if the windows panels are in good enough shape for me to buy the glass to insert.
