If it's hit or miss or not common then I probably would just do basic cosmetic updates (paint, refinish *not replace* the counter tops and tub if needed, professionally clean the grout, etc). 

They'll be "investor friendly," but likely nobody I've used in the past.For the most part, this is what we'll be doing to both of them (with estimated budgets):-  Lead inspections/clean-out/permits:  $1000-  New plumbing (and new fixtures):  $6000-  Upgraded electrical (and new fixtures):  $5000-  Install forced air heating/AC (ductwork and units):  $7000-  About 50% new sheetrock and paint:  $5000-  Flooring: $2000-  Cabinets/countertops:  $4000-  Replace doors/trim as needed:  $2000-  Appliances:  $1000-  Exterior repairs as needed (doors/windows/etc): $3000-  Misc:  $1000TOTAL:  $37,000 +/-I've done literally a 50-100 rehabs of this exact scope, though I've never done one for a rental unit. 

I was approached about a 4-plex in a decent area that's been redone (nothing crazy, new carpet and countertops)But the rent comps and the price are just terrible ROI. 

The seller had already installed new laminate floors and granite countertops.  

Also, you can imagine that people are not looking for vinyl floors and marble countertops. 

But it needs new carpet updated fixtures in the kitchen including sink, floor, cabinets and counter tops and possibly fresh paint throughout.   

You look like you have a very nice counter top and sink fixture but it's not really being showcased.

People are getting the idea it takes 20 or 30 K for new cabinets and counter tops!

Some of the things that we don't typically do that we could for relatively low cost are (keep in mind that these are houses below median price in my area - so granite counters and the like are not really necessary, but might be an option) installing fancy tile backsplashes, tile granite counter tops, under cabinet lights, recessed lighting, wainscoting/chair rails, spending more on curb appeal, outdoor living areas (large custom decks etc) and other things that can get rather expensive.I'm not wanting to spend a lot but am willing to add something extra if it will help sell houses faster.

Maybe put new laminate in a living room instead of carpeting and then do a nice tile backsplash with new countertops in the kitchen.
