The internal rate of return (IRR) is a rate of return used in capital budgeting to measure and compare the profitability of investments.The term internal refers to the fact that its calculation does not incorporate environmental factors (e.g., the interest rate or inflation).

That could mean the secondary structures are not allowed to be re-built or that any re-build must be on identical foundation (or footprint) in exact same location on the parcel.

That would involve sources in the common hallways, common mechanical chase, at the elevators, near windows at the end of the hallway, etc.I agree with Steven that the owner above or a neighbor to the side would be liable if the mold was caused by something that occurred in their spaces.As for saleability of the condo, I'd say that so long as you remove it in a safe manner and have some kind of documentation that it was done by professionals who stand by their work (and carry general liability and environmental liability insurance) then the fact that mold was there at one time should NOT be an issue affecting the sales price.Good luck.Travis W.

I use the following:MLS (need an agent, many areas are not well updated)Craigslist (probably the best easy option)Rent o meter.com (often not very accurate, but a good tool)Call rent signs (not very useful for markets outside of your footprint)Hope that helps

Environmental: As a corollary to point 2 above, when Tenants pay their own way, they use MUCH less.

Beyond understanding the financials, seasonal issues and markets, you need to understand environmental issues, the liabilities that may arise.

Federal law puts any deeded owner on the hook for any environmental damage and cleanup even before your ownership.

I am not a writer, a poet, or a prude.Chapter One " What was I thinking" January 2014I started the process by assessing/evaluating which credit tenant I wanted to focus on, and settled with the Dollar type national credit tenants.I then looked at markets within 90 miles of Tallahassee, and studied the footprint of the three major Dollar tenants looking for gaps in the foot print and assessing why there were gaps.

I've seen on the tax sale list and people bought them: side of a cliff land at bottom of man made lake land on Army bombing range House torn down in 1972 on lease land, only the house was for sale land under railroad tracks sliver of land too small to do anything with environmental problems even super fund site, if you don't know what the super fund is look it up, its not good and certainly not super.

In California we have very strict environmental standards that, depending on the location of the property, can add time to projects getting the necessary approvals, etc.
