Do I need to eat the costs then start an eviction hoping that I can at least get the missing rent from the front tenant?

You need to get these people out and get control of the situation before it eats your lunch.

If they stay great if they leave I eat the cost of a turn over and get a good tenant that can afford the rent.

I refuse to eat cleaning and actual damages as the "cost of doing business." 

What are the big-ticket expenses that are eating your lunch and stagnating your growth? 

Taking a never ending vacation eating purple ube ice cream on some Pacific Island with my dog, the Duke of Wake.Joking aside. 

Foundation repairs would eat up all of my reserves and I can only pull the trigger once since this is all of my savings. 

It allows your QI to form a holding entity called the Exchange Accommodating Title Holder (EAT) that takes title to the new property and holds it for you until the old property sells.   

Notice I made no mention of a dining room to eat in. 

Last time I rented it was 100% for location, being near the freeway and being near awesome places to eat and socialize.These are just things to ponder.
