I have a friend out of PA that sets homes in the tri-state region and I can recommend some manufacturers up your way but need to know more particulars of what you're looking for, as in basic ranch, one story/two story, etc...

That basically meets the 1% rule.

My last turn which happened 1.5 years after the last one costed ~$3000 of which the SOW was basically the same as it was the prior year it was turned.

Basically a concrete slab with pillars, hurricane tie downs and skirting with axle removed. 

This amounts to lost opportunity because if you had purchased RE, at the closing it can start producing return. 5) ADUs detract from the existing structure whether this is privacy, a garage, or just yard space. 6) this is related to number 1, but there are many more buyers looking to purchase homes for their family than there are RE investors looking to purchase small unit count properties.

I flip in areas I'm familiar with but even if not, it's not complicated to formulate comps from basic google searches.

Buyer letters were great too until they did away with those. 

I think this was to ensure your buyer can qualify for a loan.

Basically, it talks about the scope, timeline, and payment terms.

You are very detailed about your complaints, but never mention basic important details such as what kind of rental agreement was given to these tenants?
