(Sidebar: this same builder decided to create a long cantilevered overhang with laughable/dangerously short back span that has also failed and violates all current codes, but I might create a separate thread for that.)With a little 20lb demolition hammer and a pointy bit, took only 45 mins per room to bust it all up.  

I use 10 years as life span for floors except carpet then only 5 years.

The cash flow improves with time, but your 10 year span to pay off $300k via cash flow would require an average of $2500/month of cash flow.  

So $6000/10 year life span/12 months in a year=$50 per month on something new. 

Everything has a life span.

The backup from these evictions is going to span months whenever the ban is lifted.

With the "limited time span" people seem to have for reading ads, I'd rather they focus on the benefits and pertinent details of the property, ie rent amount/number of bedrooms/area. 

I think it might even be nationwide. anyways the point being its life span is approx 50 years and it can cause thousands of dollars of damage and cost thousands of dollars to fix so a sewer eval is a must.

In my situation, my bank does a loan that spans multiple properties. 

As indicated, I believe in 15 years, even with a correction in that span, the property will be worth substantially more than today in inflation adjusted dollars.
