The success or failure of your flip will have very little to do with your design decisions.

The 30 day mark has passed and from her 1250 deposit I deducted $50 for failure to remove trash and $210 for failure to maintain landscaping.  

We're willing to pull the trigger despite the shadow giants of fear and failure hovering over us and reaching into us to clench their mighty fists around our hearts, as they do to every person starting out in real estate investing.What did you do right starting out?

I have seen evictions thrown out of court for failure to follow legally prescribed methods of service.

Even if you're shot down right away in the phone call you're learning to take on failure and how to communicate on the investment/management level.

I won't accept the rent without it, and if they refuse, then I follow suite with a failure to pay eviction. 

I also tell them that I believe them and know that they will pay me, BUT I am going to give them a 5-day notice to vacate for failure to pay rent. 

In theory it works but there is a single point of failure with not being boots on the ground.

Expansive clay soil and if the structure was not properly designed and constructed, the result can be complete failure of the structure.

The main take away here being don't push your estimates to the top of the limit in order to make the investment work, at that point you're setting yourself up for failure.
