I'm dealing with three challenges: 1) roach residue in the kitchen cabinets 2) floor under the carpet is kinda gross 3) still not the best smell in the unitI contacted a company about what they would do and they wanted $150 for just an inspection and estimated treating the place (cleaning all surfaces, ozone machine, etc.) would cost thousands. 

He was looking to leave the corporate world in his early 50's using the residual income from his rentals.

If you say you want passive CF (residual income), then flipping and/or wholesaling won’t get you there.

This should pass in short order.However, if the wrong adhesives or prep materials were used during installation, then this may be an issue that will not go away quickly.

powerwasher. that residue is hard to clean. i know because i used to have a small powerwashing business. there are chemicals that are harmless to plants/people, but super effective on that stuff.

And wood expands and contracts at a different rate that vinyl and the adhesive isnt a strong enough bond to hold up.

lol, you are correct though, the tape falls off leaving dried residue that doesnt come off.

On top of that, there is overshoot; residual heat that comes after thermostat is satisfied.

There are quite an amount of adhesive off the floor underneath to get rid off and I was wondering what would be the best way to get rid of all the adhesive on the floor? 

There's always adhesive holding these in place in my areas.
