When my residual income from real estate matches my annual salary, I will then be out of the "Rat Race".

The tar/residue was so thick on the vinyl window frames it had to be scrapped off then scrubbed.

Additionally, the residue that's left behind can cause some paints to literally slide off the wall, much like you see with heavy nicotine staining, but much, much worse.  

The solution for the residual odor was to spray every square inch of the interior in the fire area with two coats of Zinser BIN Shellac using an airless sprayer, forcing the BIN into every crack and crevice.

Boric acid is what you want for residual roach killer. 

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.

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.

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