They don't invest in their business enough.undercapitalization is the #1 reason for business failure, wholesaling is no different.

Imagine, you're meeting with a sheetrock contractor on site and he says it's gonna cost x for the job, and you whistle and exhale and sigh and then say...well that seems like you'll be charging me y per installed board and I know the /board installation rate is closer to z and I have estimated abc number of boards... well it adds a level of professionalism and confidence that can sometimes make the difference between success and failure. 

All roofs have pros and cons and we could definitely debate it all day and all be correct but where EPDM roofs have failure is from shrinkage, seam pops, and puncture resistance.

The notice comes with 0.5% monthly interest and the following threat: "Failure to pay will result in the cost becoming a tax lien against the property or a personal debt turned over to a collection agency."  

Doing volume mitigates the risks by covering the occasional failure with successful deals. 

IRS liens are not always recorded in the deed records with other liens.While the idea of extinguishing all liens on a property upon a tax sale and gaining title free and clear is exciting, the reality is that many of the properties posted for tax sale either (1) do not have any equity (they are not worth what is owed in taxes),  (2) they never actually get to auction because a lender pays the taxes to protect their position (usually failure to pay taxes is default under a deed of trust or mortgage) (3) bidders at the auction bid the property to a wholesale or retail amount thus eliminating the potential profit.  

Failure is not an event.

If you "Run until Failure"  you will likely pay double for the after-hours or expedited service. 

Macro they get, but micro is where true fortunes or true failures are made.

Basically you cant do it for anything other than failure to pay rent or taking the unit off the market permanently.
