There is a lot of headache and the section 8 process is management intensive.

@Scott Trench I do think you could get the costs down by doing some labor - the process is labor intensive - digging the hole alongside the house and removing the concrete are the biggest items, everything else is relatively easy - with exception to cutting the hole - that is pretty important to be accurate!

In other words, I need help estimating by intensively looking  (from photos and/or video) at what cost I can ballpark.

Some of the regulations include providing a bathroom on every floor that contains a bedroom and installing new insulation.All rental properties must be put on a list and are subject to an intense inspection every two years to be paid for by the landlords.Landlords who fail to comply could face fines or other legal action.But the council believes the changes will reduce blight and crime in the city."

Wasn't sure where to place this, but I have over 1000 sq. ft of old basketball court flooring available for your projects.

Flipping a house, even if Dennis does 2-3 a year, still takes months to complete plus if he has a home office in which he runs the flips from and researches for new property all while taking the tax deduction for it, is all running a business and i would be very careful playing that gameAgreed, this is a highly subjective fact intensive determination and border line cases are notoriously difficult to predict, with selected outcomes at times being contrary to what one would expect.

The tiling in the bathroom alone is labor intensive and extensive because it needs to be prepped for a wet and humid location. 

It is labor intensive requiring a lot of man hours.

I guess I look at investing a little like playing basketball.

Snohomish county’s TDR program seeks to use market forces to discourage residential development of important natural resource lands, considered “sending” sites, and redirect this development to more suitable lands, typically within urban growth areas, considered “receiving” sites, that are appropriate for more intense residential use."
