So far when I put the counter-top depth fridge (normally $1699) in the cart and check out online I am getting $1363 + 109 tax for a total of $1473.Is there something I'm missing?

Typically the plumbing will have some issues, door and window frames may shift, cabinets and countertops may shift, cracks may develop in walls, etc, etc, etc. 

While searching for properties I personally always take into account my BAH rate to ensure my mortgage is well below that, what would the property rent for today if I had to move short notice (or deploy), and what value can I add to it over time (electric garage, upgrade kitchen appliances and countertop, new flooring, improve landscaping, new paint).

Quality paint, stains, cabinet and counter top resurfacing all dirt cheap. 

But again, the $/sqft metric doesn’t account for that.The ConditionIf a house has a brand new roof and a completely high end remodeled kitchen with granite counter tops and stainless steel appliances, would you expect to pay the same amount as you would for a dated, 1950s rancher?

The second floor (3/1) and third floor (2/1) were light turns consisting of all new windows, countertops, updated bathrooms, paint, refinished HW floors, and new electric and plumbing fixtures.

The second major salvage operation was the removal of the kitchen cabinetry and countertops.

When people downgrade they move from the shiniest new countertops to a classic unit priced $100s less.

We just replaced the kitchen cabinets and countertops in one unit- we went from plywood cabinets with laminate doors that were falling apart to the Project Source brand unfinished cabinets from Lowes which have solid wood doors.  

Or you can give it the appearance of being attached by unitizing it with flashing, siding and trim details.Both are available with the same array of flooring, wall & window covering, counter top, appliance and fixture choices throughout.Both can be prepped for tile, shake, composite, or any of the same roofing choices that site built homes use.Both can be sided with anything the designer chooses including stucco albeit the sections are shipped stucco ready and the stucco is applied on site.Both are available with drywall interiors.
