They were decent solid wood cabinets and just needed some refreshing.

Assuming our reasoning is correct, how much of a premium should we ask? 

By leaving these areas saturated, any wood structure or metal framing is subject to deterioration, and, depending on your locale, will also attract wood destroying insects.IF your rental agreement addresses responsibility for the lawn care, AND, again, you have proof of the damage in the form of "move in condition" documents and photos, I would insist that be restored prior to them vacating.

Laminate wood flooring can be purchased at any box store with price ranges from $1 pSF to $3pSF.

Very basic 2 story 3 bedroom 1 bathroom units (2 mini houses on 1 parcel of land) so the main things to update were paint, counters to granite, made the cabinets look better with wood work and paint.

Anyway, I'm in your neck of the woods.

These houses will have 2 washers, 2 dryers, 2 fridges, plus entertainment like a streaming Blu Ray player, HDTV, kegorator, fire ring with fire wood outside, ping pong, darts, exercise equipment and free weights, etc. 

Don't buy anything numismatic or with a premium,imo.

Here's a checklist I would use for a Dayton duplex that's good for cashflow.Rental neighborhood, no warzones.Rent ready or closeNo upcoming large expenses (roof, windows, furnace, etc)Double pane windows (pref) or single pane with storms (acceptable)No wood siding.Tenants pay all utilitiesMonthly rent 800-900 for a two bedroom, 1000-1200 for a 3 bedroom.2% rule. $800 gross rent = 40K max priceReduce price by major expenses, and to correct items above.There's some variation depending on the submarket, but this list would get someone started right.

I working out of the detroit harper woods areas also but if you DIY-er you can save some cash and just pay for labor.
