They estimated $98,000 for the job and wrote this, basically saying that it's impossible to fix without also replacing the drywall and insulation, and that chemicals and paint would not be enough:"The odors and residue from the smoking are very apparent and appear to have permeated all areas of the Residence to such a level that these odors and residue, that is oil based, cannot beremoved by means of scrubbing with a detergent solution, application of a deodorizing solution, and application of a stain blocking type paint.

I did try a chemical to remove the paint on a door and man that took a while and it wasn't the cheapest as you have to do it a few times.

It depends.Real Estate Investing is a great strategy for financial freedom but without formal education to get a good job that will allow you to have a substantial downpayment or buying real estate with cash, Investment may not be possible for that individual except you want to start with bird-dog (Wholesaling, Real Estate Investor Apprenticeship, Assistant etc).I have a Bachelor and Master's Degree in Chemical Engineering and I will say (with confidence) that it all worth it.Goodluck man!

I imagine a tenant flushing down chemicals and other things that's is going to ruin the whole system seems like a recipe for disaster. 

Worked with a Local LenderMy thinking at the time: A national lender will have broader reach and economies of scale to give me a lower interest rate and lower closing costs.What I should have done instead: Found a local lender who I can build a relationship with for the long-term.My lender was Chemical Bank, which is a national lender that's been around for a few years.

I've used Chemical Bank...........I've heard they now do loans for as low as $35k Mortgages

Also, you have to check the chemicals every day to make sure everything's cool, but it's about a 2-minute commitment, plus vacuuming once a week.

We have treated twice with chemical treatments and the tenants have been steaming, drying and vacuuming constantly.
