Personally, if they hav a voucher I apply all my same criteria except the income component.  

My first deal was one of those perfect alignments of stars.

Also I would go with 10% for CapEx until I have the property inspected and know the condition and expected useful life of all major components.  

Your logic doesn't not align with the Bank's logic and as eloquent as your position has been stated, I can tell you that it's not the bottom line above all else that matters for the vast majority of banks out there.

Have the property inspected to determine the condition and usable life expectancy of all major components and appliances.  

Freedom from payments sooner aligns with that nicely.

After a two-month decline, consumer sentiment in the state rose 2.1 points in June as four out of five components moved higher. 

And if prices soften more, you will be well aligned to make your next move. 3- the value of an SFH with an ADU in YOUR SPECIFIC CITY AND NEIGHBORHOOD is an Important question for you to understand.

Once you determine the current condition of the property via the inspection you might need to alter that price.Also use the inspection report to determine the current condition and usable life expectancy of major components and appliances on the property.  

@Austin Underwood at your building value level, a cost Seg study will provide only a marginal benefit over what you could be doing for free:Since you are building these homes, I'd assume you have all the cost data of every component, no?
