Who wants to waste time with a brush when you can spray :D

It will spray out when they bend over to get a drink.

I say preflip because what we do is go into a property and trash it out, spray all walls ceiling and trim eggshell white, spray the outside of the outside with kilz2 with a color tint one color, clean the lawn, cut it and put mulch down.

Repairing walls, spray painting the whole building with maintenance paint and adding 0.29-0.39/sqft laminate flooring throughout could probably be done under 5k. 

They come once every two months, spray something in each unit and charge $110.

(for my mother)Add master bathroom on second floor (would be placed directly above the kitchen and across the hall from another bathroom)All new systems (2 Zone HVAC, Plumbing (copper pipes), and electrical)I intend to use Spray foam insulationThe entire house would use low-mid tier materials with certain splurges(hardwood, kitchen cabinets)This will not be a rental, I'd live here.

According to the realtor the damaged areas were removed, dried out, and mold inhibitor was sprayed throughout. 

Encapsulate everything, open every window, and spray bleach everywhere. 

I also found a company that would spray - reglaze your tub for about $350.

Tell them you spray for bugs for up to 30 days after they move-in and after that you charge them --explaining that they have to keep the TRASH OUT, decent housekeeping is expected.If possible-- maybe market as an all GRAD student condo?
