Saw an interesting job where they coated the old stucco with a spray on cork finish..very impressive.https://buyspraycork.com/

The pest guys come in an spray, they don't do any real prep.

Eventually,  what I did is buy my tenants pest control spray from Home Depot and ask them if they would like me to spray.

Power wash it then decide if it's sound enough to just spray with a good coat of exterior paint, easy spray paint job top to bottom inside & out. .. touch up trim with a accent different color.. it's cute. 

Wall wash with TSP prior to painting if possible,, if the ceilings are flat (not popcorn) wash also, a sponge mop with a towel over it works great and fast..2 buckets one wash one rinse.you wash everything,, doors, trim, floors, cabinets, light fixtures, all windows glass and tracks.Bleach is ok to use but I've found that TSP is best thing to actually REMOVE the nicotine,, you'll be shocked when you see how well it works. 2 Prime, Kilz primer to seal anything your going to paint.3 Remove all blinds, throw them away the plastic retains the odor and they'll be gross anyway.4 Air Ducts if you can reach inside wash out.. then spray Kilz in them as far as you can reach with the system off.  

We first sprayed ~50/50 bleach everywhere to just kill gross bacteria and then went back with odaband (fungicide).  

they are ok thank God.I did a walk thru of the unit yesterday and took them some bug spray trash bags case of water and sprays to just give a helping hand.  

I sprayed the carpet heavily, let it dry, and sprayed one more time.  

Spray knockdown texture on walls?

A neighbor told me that she had been raising manx cats, and both houses reeked of cat spray and urine.
