Whether permitted or not, the slab likely has little to no footing and it's not likely it includes a vapor barrier, plus the span on the 24" on center ceiling joists is likely too far, and when you sheath and shingle it will get worse...assuming there is even a world where it would be viable to insulate sufficiently and pass Title 24 etc. 

Flooring has a 10 year life span. 1000*$6=$6000. $6000/10 year life span/12 months in a year=$50 per month budget for flooring.

My capex budget includes roof 25 year life span, floors 10 years, hvac, 20 years, appliances and hot water heater 12 years, bath and kitchen remodel 20 years, etc.

The tree spans over my house and partially over the neighbor's house.

I did this over the span of 2.5 year sand went from zero to twelve doors. 

I have worked with multiple investors who have set up their properties this way, but it's a very small percentage (a fraction of 1% of all those I have worked with spanning a wide range of overall property net worth sizes).Another potential negative is currently the 2017 title examination standards for Oklahoma say that the series' are only an "attribute" of the same LLC, not truly a subsidiary capable of acquiring, holding, and conveying real property in its own name.  

Geographically it is strategically positioned reaching 34 million people.... 40% greater reach than the I-4 corridor which spans from Tampa, through Lake Land, Orlando and then ending in Daytona (coast to coast).

If carpet has a life span of ten years and it has to be replaced after five years, you should only charge the tenant 50% of the cost because that's the remaining life span.

DC requires a bedroom to be 70 square feet, and at least 7 feet across on the narrower span.

This would probably lead to an accelerated depreciation of fixed assets and machinery and short life span for expensive equipment.
