Instead this one property has allowed me to put about $3MILLION back into the economy in repairs, purchases, remodeling and capital improvement in 4 states.  

So, the quote to do the mold repair is $3500.

But, the one person who does want to sell, saves $20,000 in real estate agent fees along with $10,000 in repairs and saves the uncertainty of how long it will take to sell on the MLS.He then fixes up the property and sells it and makes maybe $30,000 and sends out another mailer that costs $1 a piece to send out.
