How detailed should one be in predicting CapEx(expense side) and neighborhood/local trends (income side)?

But you can't predict those things.In my part of L.A., a decrease in home prices wouldn't affect the rents very much, but that's very case-by-case, market-by-market.

When a borrower is current on the 1st they're behavior becomes more predictable.

Deff have taken these aspects into consideration when trying to predict the assessed value post rehab.

So now there are some serious El Nino predictions officially coming in.

My personal prediction is that this complex, which is already under valued, will just increase dramatically once the revitalization is complete and the light rail station goes in.  

UCLA who predicted last bubble, well they say no.

No one can predict what this market will do, but Medina is an awesome neighborhood.

We can't predict the  future but we can plan for it.  

Furthermore, if the 2 investments had the same cash flow at the same time, from the time of investment until the time of sale, then they shall have the same IRR.However, of course, as I cannot predict the future and since I also cannot even predict taxes, I thought of estimating IRR without taxes, hoping it will not be that different from an alternate stock market investment.
