In one unit the termites are in the walls, in closet shelving, such that when it spray it's dropping every few days, the closets are basically not usable. 

The sprayed loose foam packs down over time and becomes massively less effective; especially if it comes in contact with moisture.

Sometimes you can cheat by spray buffing, but I recommend doing it right.

Other items could have been addressed before hand with a 3 dollar can of spray paint.I made money on this one.

I still hired one (horizon) that costed $200 and sprayed the house, just show my tenant that I am working on it.

This was a finished basement and it sprayed through the wall for 2 hours + I spent that Sunday sucking water out.

We roughed up the fiberglass with sandpaper and then sprayed the paint with an HVLP gun.

i hire a company that comes out and sprays the tiles and tub with special enamel. it's about $250 per tub and around 350 for the shower tiles.they have 5 yr warranty and make it look like new. it's not FLAWLESS, but it's great and cheaper than a new bath.used them about 5 times now.

On our lower end rentals we would just buy unfinished cabinets, and do a light sand and then spray them with polyurethane from rattle cans.

Macy level is the happy medium between profits and expenses.Deal Breakers I have found are LocationCleaniless InternallyCurb appeal (cleanness, landscaping (fancy not required just clean up)No Carpets, tile, laminate, hardwoodFresh paintUpdated (again doesn't have to be perfect but the right paint and flowing can bring anything up to date even with a blue tub) Paint can bring the cabinets into this decadeWorking/Funcitonal/No appearance of issues (cracks, filled in, etc)One step up (garbage disposal, dishwasher, automatic garage door), etcUpdated hardware (kitchen, light fixtures, etc, spray paint can work great)Some bonus if cheap, I would also put in.
