(actually these "excuses" all go back to "lack of knowledge")9 - Listen to others (such as the famous "everybody"...as in "everybody knows...") telling them "it can't be done"...and uttering those famous words of all failures..."

I always recommend to my landlords to put in the lease a clause saying something like the tenant is required to carry and show proof of renters insurance and that their failure to get renters insurance nor your failure to inspect for renters insurance relieves them of the duty to carry it.

The statistical probability of failure with business within the first 1, 5 and 10 years is so high, that few of those who started will last.

So she called the landlord who had evicted her 8 years prior (for failure to pay rent), apologized, paid back all she owed and put down an extra security deposit to be able to rent our place.

For those more experienced, do you just do things and assume you'll lose money  (maybe or maybe not) and get over the fear of failure?

There are too many swirling tornadoes of vague fear and failure that go on in this business and too many smug self-congratulatory types who never get tired of patting themselves on the back or putting you down, and preferably (for them) both.I know the jargon at the auction can be overwhelming.

Excerpt from our rental criteria:RESIDENCE/RENTAL HISTORY1.We will examine the most recent five years of residence history and all legal history.2.Home ownership will be verified through the tax assessors office and/or credit report.3.Rental history will be verified through the property owner and/or rental agent. 4.Rental history reflecting any unpaid past due rent, damages or fees will result in denial.5.Rental history showing excessive property damage, excessive noise, or unruly behavior will result in denial.6.Three or more notices for failure to pay rent and/or to comply with the terms of the rental agreement, within a 12 month period, will result in denial.7.A person with an eviction or unlawful detainer on their record may be approved if full restitution has been made.

In many places, you can not evict for a tenants not having paid late fees, utilities, etc - you can only evict for failure to pay RENT. 

However, I am unsure if I should post another notice on the door to failure to pay rent?

As I stated, I am just trying to get my foot in the door and want to make sure I am not setting myself up for failure.
