My buyer has little recourse except to take seller to court.   

I did not have any costs associated with my first few wholesale deals except that I took a contractor with me to get a bid for repairs on the first 4 or 5.

Afterward, grab a drink and food at Denver Central Market to get a flavor of one Denver's many food hall concept. 

Very few real investors  are opposed to wholesaling if the numbers make since except @James Wise ;) he is against it. 

I am actually pretty open to all of  your mentioned criteria, except the the first...1.

The option of selling now and waiting to buy might be a solid option except you will not be able to do a 1031 exchange, which may not be a problem since you have lived in the property for 2 years.

Except for one problem... 

As far as I can tell I've got identical coverage on every property.I talked to my contractor ,who has built houses from scratch, what it would cost to rebuild these in the event of a total loss situation and he said that $200,000 is the max on all of them except the all brick 1750 sqft one...which would be closer to $250,000. 

Washer & Dryer is the exception to the "big" appliances that I provide.

They provide a chart, based on their experience, that gives you per-square-foot costs for each combination (except anything to do with "Custom," since, by definition, it's custom and can't be ballparked).Based on their chart and my (admittedly subjective) ratings of "Standard" finish level and "Remodel" scope-of-work, costs should be roughly $25/sf.
